Home Air Conditioning Services for Your Ease


Air conditioning has to be functional and efficient. However, maintaining efficient air conditioning in a hot place is no easy task. With the sweltering heat that comes with summer, you need home air conditioning services that can service and sustain your air conditioning units so that it can take you through the summer months.

Some places are known for their outdoor beaches and beauty. However when you need to be indoors, air conditioning should be cool and inviting increasing the place's desirability.

Summertime is really rough on air conditioners, which is why home air conditioning services are absolutely coveted during the sweltering months. Due to all the strain on air conditioners, the moving parts inside the system tend to wear out, which is why owners often end up resorting towards air conditioner replacement when it is too late to repair and maintain the air conditioner.

When you call a home air conditioning services company, you always make sure that they offer the most basic services. One of the simplest methods of A/C servicing is listed below:

Always Check For Clogged Up Drains

When you call home AC services, they have a few standard procedures to follow when they are doing standard maintenance for air conditioning units. One of these processes includes checking for clogs in condensate drains.

A condensate drain is the drain, which opens on the furnace, starting from the cooling coil drain, it runs all the way down to the floor drain.

The primary cause for clogged up drains is the presence of bacterial slime in water. When your air conditioner is running, the servicemen will check the spot where the line drains into the floor drain just to check if the water is actually getting drained.

If the water is not being drained then the presence of a blockage is confirmed. Once this is confirmed, the servicemen turn to check out the drain hooks and the drain pan on the surface. To start off with, they turn the air conditioners off and then go about unclogging the drain.

There are several ways of unclogging drains. Servicemen usually do not use chemicals to unclog them but use mechanisms like 'drain snakes' that go through the drain till they find the clog and remove it. Other methods include using plumbing wrenches, or using baking soda and vinegar with hot water to unclog the pipe. It is usually better to opt for professional services as far as your HVAC system is concerned.

Air Conditioning Filter: Essential Part of Heating and Air Conditioning


The air conditioning filter is one of the most important air conditioning parts in the air conditioning system. Without it, your air conditioning system would be dirty and the air you breathe would be filled with pollutants. All air conditioning parts, from the ductwork to the air conditioning refrigerant, need the air conditioning filter to be clean and replaced to ensure you're getting the very best in central air conditioning.

If an air conditioning filter is left dirty, over time, it can lead to higher energy costs and short
equipment life due to all the air conditioning parts relying on each other. One can not work without the other. Overall, your heating and cooling will not be as effective and you will need to invest in more air conditioning repair and air conditioning maintenance.

An air conditioning filter should be changed every month or every two months for home air conditioning systems and every couple of weeks for certain commercial or industrial air conditioning since it's running almost 24 hours a day, 7 days a week. Doing this as a routine in your monthly chores and not waiting until you see dust matted on the air conditioning filter will ensure you and your family the very best health as well as a smooth running air conditioning system . Dust particles can not always be seen so even if you see a little dust on the air filter , clean it as you normally would.

Since there are a variety of air conditioning filters , how quickly one gets blocked versus another depends on the brand - most air conditioning filters are sized 1 ½ to 2 square feet for each ton of capacity for a home or commercial property.

You can judge a filter's ability to clean by using MERV ratings - Minimum Efficiency Reporting Value - which is a rating of how efficient an air conditioning filter is from 1-12. The higher the rating, the more effective it is at removing particles such as animal dander, pollen, dust, mold and other allergens, and the better the protection for your air conditioning equipment . Most air conditioning filters screen out particles measuring from 3 to 10 microns in size.

The common types of air conditioning filters are:

Conventional fiberglass disposable filters (1" and 2"): These are common in most homes and small industrial air conditioners and commercial air conditioning systems. Since they are disposable and have an adhesive coating that traps the dust, you should not clean the filters . This may damage the filter's ability to remove particles by damaging the adhesive coating and/or the underlying mesh work. They are both not as effective as other types of filters even though they are lower in cost.

Pleated fiberglass disposable filters (1" and 2"): The 1" are generally used in many residential and commercial settings and are made of materials that can vary in the effectiveness. Usually, they are more densely woven to increase the efficiency of removing dirt. These have a larger surface area to lead to increased trapping of particles as compared to conventional filters. They must be specified for your air conditioning system or this can lead to increased demand on your air conditioning components. Thereby, a mismatch can be counterproductive on the health of the air conditioning system and possibly lead to higher air conditioning maintenance and service cost. You should check with the air conditioning manufacturer as to the appropriate type of pleated filter for your system. A filter spray can also be applied after the cleaning and drying of the air conditioning air filter .

Electrostatic filters: Different in design and performance, since there are so many varieties, it is rather difficult to determine which is the most efficient. They are commonly advertised as allergy-free air conditioning filters. These filters also come in the 1" and 2" sizes. Air that moves through the filter creates a static charge that collects any dust in the filter. They may require more cleaning and more blower power.

Electronic filters : Connected to an electrical power source and usually wall mounted, electronic filters come with a pre-filter that can collect larger particles and only need to be cleaned every six months.

Carbon filters : These filters contain carbon that can control any odor problems you might have within the air conditioning system . They can also be useful in homes with pets.
Air Conditioning Filter Installation

When placing the appropriate air conditioning filter in to the system, the filter should be placed in the correct direction as indicated by the arrow located on the side or face of the filter. Air should flow in the proper direction which is in the same direction as the arrows. This allows the filter to work appropriately, as the air exits the filter in the most reinforced part of the filter.

The air conditioning filter should fit tightly. A perfect seal is necessary to prevent unfiltered air from entering and damaging your air conditioning system. Without a perfect seal and appropriate sizing, the filter is useless. Additionally, the non-conventional filters may have a higher efficiency and may not fit your system. This should be checked with an air conditioning company, contractor, or air conditioning supply company.

Indoor Airflow From Your Central Air Unit


Most people have a central air conditioning system. We all know the air comes out of vents that are in different rooms in a house. Most of us know that there's an air filter somewhere in the house that needs to be changed once in awhile. There are some other things about the airflow in a central air system that may be of interest to people. Did you know the air conditioning vents are located in precise places? Did you wonder why the thermostat is located in that hallway, or why two story houses usually have two air conditioning units? These questions and others are easily answered, and can empower people with some of the basic knowledge necessary to maximize the life of their central air unit.

The vents located in each room of a house are usually placed where they are for a reason - to maximize airflow in the room and to keep the air circulating throughout the entire room. These vents have baffles, or fins, on them that direct airflow in certain directions. If you look around your home, you may notice that some of the vents are one-directional, while others are multi-directional. The object of the multi-directional vents is to cover as much area as possible in a room and to keep a room from having 'hot spots'.

The thermostat in your home is probably located in a hallway. This is the spot where the temperature most resembles that of the rest of the house. In other words, the temperature where the thermostat is located is the average temperature of the home. For this reason, the thermostat is usually located in a central point in the home. After all, you don't want the air conditioner or heater to kick on when part of the house is freezing, while another part is just right.

Air circulation is critical in a home air system. As each vent, or register, discharges a certain amount of air, there needs to be someplace for that air to go. If there were nowhere for the air to go, it would cause positive pressure to build up in the home. The efficiency of the unit would be drastically reduced too, as it struggles to force more air into a positively pressured environment. The good thing about positive pressure in your home would be that no airborne particles would be able to enter your home since they would be forced away by the pressure escaping the dwelling. The cost outweighs the benefit though, as the high electric bill and shortened life of the unit will cost substantial money in the long run.

To make sure the unit works as efficiently as possible, there is a return air grill, which usually houses the air filter. This return air grill is located in a place where all the circulating air of the home is able to be cycled through it. The air is then cleaned, cycled through the evaporator coil located in the air handler, and redistributed throughout the house. As this is done repeatedly, cooler air is recycled, so that the unit brings the temperature to its desired setting quicker, and the change in temperature from air going into the return and coming out of the return gets smaller. This allows the unit to maintain the temperature of the home by running for relatively short cycles periodically. Then we can enjoy our lower electric bill.

Larger houses typically have different zones fed by more than one air system. When a house is on a horizontal plane, as a single story dwelling is, it's easier to regulate the temperature throughout the home. There's typically a problem with two story and taller dwellings though, which makes it harder for the temperature to be regulated. In warmer seasons, the air conditioner is used. In colder seasons, the heater is used. As we all know, heat rises, so in the winter, the heat all goes upstairs. But in the summer, the colder air all goes downstairs. It's a tough problem to solve. This can be done if you block off the two zones. This can be done by closing the doors to each bedroom. Another way to do it is to close the vents downstairs in the summer and upstairs in the winter. Neither option is very effective, so most people just live with the discomfort.

As you can see, your central air system has a little more to it than random airholes in the ceilings. Not all contractors are trained to design systems, so extra care should be taken to hire an experienced HVAC contractor to perform your new construction design... or while you are having your plans drawn up, have a mechanical engineer design the air conditioning system. It may cost a little more, but it's well worth it to keep your house as comfortable as possible.

Equipment Breakdown Coverage For Property Owners


Many property owners have the misconception that their property policies include coverage for equipment that is installed in their buildings. While the standard property policy can provide coverage for the structure, contents, and potential loss of revenue in the event of a loss, equipment breakdown is excluded. In order to avoid a coverage gap, property owners also need an Equipment Breakdown policy, which is tailored to cover the loss exposures for equipment and systems installed in their buildings.

Equipment Breakdown was formerly known as Boiler and Machinery coverage, but was rebranded to more accurately describe the expanded range of covered equipment. Equipment Breakdown includes coverage for electrical systems, air conditioning and refrigeration, boiler & pressure vessels, electronic technology systems, and mechanical equipment. Without an Equipment Breakdown policy, owners are self-insuring substantial loss exposures to their property.

ELECTRICAL SYSTEMS

Electrical systems, which can be a significant investment in the overall building value, are critical for the normal operations of all businesses. A breakdown can impact both building owners and tenants. Since transformers, panels, and electrical systems are typically interconnected, a short circuit can quickly spread and destroy large sections of the system. The costs most often associated with this type of loss include system repairs, generator rental, relocation of tenants (when required due to extensive damage), and loss of revenue caused by building inaccessibility.

AIR CONDITIONING AND REFRIGERATION

Air conditioning and refrigeration breakdown can result in business closures, spoilage issues, and revenue loss for both property owners and tenants. This equipment seems to break down at the most inconvenient times and repairs can be very expensive. HVAC units are often located on the roof of the building and so replacement can require rental of a crane or helicopter. Breakdown during a heat wave could require taking actions that result in additional expenses and loss of revenue, such as closing a restaurant, moving hotel guests to another location, or sending employees home and shutting down operations until repairs are completed.

BOILER AND MACHINERY

Boilers and pressure vessels are subject to explosion, cracking, collapse, and bulging. Any of these can result in loss of hot water or heat for a building, and would require that the owner arrange for necessary temporary equipment, as well as take care of the permanent equipment repairs or replacement. An attractive perk to the Equipment Breakdown policy is that the insurance carrier performs annual inspections of insured boilers to ascertain that they meet jurisdictional requirements.

ELECTRONIC TECHNOLOGY SYSTEMS

The Equipment Breakdown policy covers damage to sensitive electronic equipment caused by a power surge. In addition to the obvious electrical equipment described above, a surge can impact phone systems, computers, satellite systems, retail systems, security and fire alarms, and other equipment that relies upon electronic technology. Frequently, the surge protection systems in place are inadequate, providing protection only for computers and not the other items that can also be affected by a power surge.

MECHANICAL EQUIPMENT

Mechanical equipment includes water pumps, ventilation fans, elevators, escalators, motors, engines, and most other mechanical equipment used to run your building. A breakdown can instantly place a building owner or tenants in a serious situation. For example, water pump failure can result in extensive water damage to owner's and tenants' property. In the event of an elevator system breakdown in a high rise building, tenants may be inconvenienced or trapped, and look to the building owner for compensation.

EQUIPMENT BREAKDOWN COVERAGE

The Equipment Breakdown policy covers damage to insured equipment and resulting loss of revenue (Business Income) while the equipment is being repaired or replaced. It does not pay for normal wear and tear. The policy can be endorsed to include Contingent Business Income, which responds if a key vender or supplier can't meet their obligations to the insured due to a mechanical breakdown of their own. Primary causes of loss include power surges, short circuits, and mechanical breakdown.

Equipment Breakdown coverage can be obtained through your property carrier or as a stand-alone coverage. Not all property insurers write this Equipment Breakdown coverage, but the important point is that this cost effective coverage is available. If Equipment Breakdown is not already included in your current property insurance program, we will be happy to discuss coverage options with you.

Air Conditioning - The History of Air Conditioning


Just like a long summer day, the history of air conditioning spans over centuries in time. Many people do not think about how this modern day convenience has evolved over time. Their main concern is that when they turn on the thermostat, the system provides immediate relief and comfort from the heat outdoors. But, just like most of today's technology, the cooling industry has come a long way. And, one can venture to say that it has more advances just waiting to be explored and developed. So, the next time you turn on the AC, you will be grateful to all those who came before you to provide this service.

The process of air conditioning involves dehumidifying indoor air to the thermal comfort set by the thermostat. Broadly, the term refers to any form of cooling, heating and ventilation that is supposed to modify the condition of the air. As far back as ancient Rome, this concept has served mankind. Back then, the wealthy Romans had aqueduct water that was circulated throughout the walls to provide cooling temperatures. Following Rome, medieval Persia used cisterns and wind towers that cooled houses and building during the hot summer season. A Chinese inventor, Ding Huan, of the Han Dynasty, invented a rotary fan during the 2nd century. This device had seven wheels and was powered manually.

By the 8th century, the Cool Hall was built in the imperial palace, and included water powered fan wheels used for air conditioning. Rising jet streams of water from fountains were also used. Egyptians invented ventilators which were used in Cairo during the middle ages. This system was not just for the rich; nearly every household in Cairo had a ventilator.

Benjamin Franklin and John Hadley, a chemist, were involved in an experiment in 1758 involving the principle of evaporation to rapidly cool object. The experiment confirmed the theory. Using highly volatile liquids could decrease the temperature of an object past freezing. More than 60 years later, a British scientist and inventor named Michael Faraday made another discovery. Compressing and liquefying ammonia would chill the air when the ammonia evaporated.

During the 19th century, advances in chemistry have given us the modern systems of air conditioning with which we are most familiar. Willis Havilland Carrier invented the first large scale electrical system in 1902. These are but a few honorary mentions who have contributed to our present day enjoyment of cool air. So as you can see, we have many societies and individuals to thank.

Air Conditioning Service Tips to Keep Your AC System Running As Powerful and Efficient As Possible


Many homeowners don't consider maintaining and servicing their AC unit until they have a cooling problem. This is what often leads to inefficient airflow, higher utility costs and replacement parts.

Air conditioning systems may be the most expensive appliances homeowners ever have to purchase. The good news, however, is that they can be maintained and serviced relatively inexpensively. Below you will find some air conditioning service tips that will help to maximize the life of your air conditioner, while saving you money on cooling costs and repair bills.

Do It Yourself: Air Conditioning Service Tips That Can be Done In An Afternoon

While not every person is skilled enough to replace worn parts inside their condenser unit, there are plenty of things you can still do to keep your air conditioner running in tip-top shape.

We'll start with the most common cause of air conditioning inefficiencies, and go ahead and suggest that you change your filter, and change it now. Chances are, the filter that is sitting inside your machine is the exact same filter that was there last year, and possibly the year before that. Filters get clogged with dirt and debris, which impedes the airflow your machine needs to run properly. A dirty filter can also cause another, more expensive, side effect. It can cause the evaporator to freeze up, and in the event that it does happen you will find yourself calling a service technician on a sweltering summer day. Filter changes are recommended at least every 30 days in the summer months, and the price of new filters is easily offset by the efficiency of your machine.

If you happen to have covered the top or the sides of the condenser with lattice, plants or any other aesthetically pleasing cover, now is the time to remove your beautiful structure or garden. Covering the condenser unit restricts airflow and all plants or other covering materials should kept a minimum of 24" away from the sides of the unit, with nothing covering the top.

Hiring An Air Conditioning Technician To Perform Routine Maintenance

You shouldn't wait until you have odd sounds or smells coming from your machine to have it checked out. Having an air conditioning technician perform maintenance on your unit once a year can save you plenty of money in the long run, not to mention the complete discomfort you may experience if your machine decides to break-down on the hottest day of the year.

Consider having an AC repair technician perform a tune-up on your unit in the spring, before the weather warms up. This will give you peace of mind for the coming summer months, and give you ample time to save for a repair that may be needed. During a tune-up, technicians will inspect your condenser for leaks and check electrical components and controls to ensure they are in good working order, as well as deep cleaning the evaporator and condenser coils. Technicians will clean the AC drain, and this can be crucial for your home. Any backed up water will be cleared out, saving the structure of your home from potential water damage, which can also lead to a full-blown mold remediation if it goes undetected. They will also oil the motor if it is necessary, check the filters and the condenser itself to spot any minor problems before they turn into a more expensive situation.

Discover The Benefits of Computer Room Air Conditioning


With the large number of computers and technical equipment that is contained within the typical server room, there are several things that must be considered when it comes to the room's environment. Computer room air conditioning is one of the most important pieces of equipment within the server room that should not be overlooked. When a complete room air conditioning system is installed, there are many benefits to be found.

The computer equipment that is typically put to use within a server room is often running all day, every day. The constant running of all equipment generates a substantial amount of heat that needs to be cooled with computer room air conditioning in order to keep the equipment running. If the heat is too intense in the room, more problems can occur, including breakdowns of the computers and servers, as well as slow performance. By keeping the air within the room cool with a computer room air conditioner, breakdowns are less likely to occur.

All equipment in the room also needs to have the correct humidity level in order to function at it's best. The server room air conditioning will not only control the temperature level, but it will also control the humidity level as well. If the humidity level rises above 55%, damage to the computers can occur. While this may not be a factor in all locations, many areas located around the United States need the humidity control so that malfunctions do not occur. Any moisture that builds up within the equipment due to increased levels of humidity will likely destroy the equipment, making replacement a necessity.

Computer cooling is necessary for the overall performance of the computer equipment as well. Servers can run much faster if the temperature and humidity levels are kept at the optimal level. Another benefit to having computer room ac is that the overall cost of operating is much lower because less breakage occurs. While the computer room air conditioning unit may add a substantial cost to running the business, there will be no need to hire technicians to repair the equipment during off hours and downtime due to equipment malfunctions will not occur.

What Is the Average Price for New Furnace-Air Conditioner?


Many people purchase their very first furnace-air conditioner without even knowing about it. Usually when they buy their home, the HVAC system is already installed. Even when people purchase their next HVAC system they often open the contact book and call the foremost HVAC contractor mentioned on the list. This strategy will help to keep the house warm but can lead to spending an amount which is more than necessary.

There are many ways by which one can minimize the cost of buying and installing a new furnace-air conditioner. First contact several HVAC contractors to request a bid. Keep in mind that the decision an individual makes should not just depend upon the cost of the equipment alone. Choose a reputable contractor as it is very important in identifying the overall price and satisfaction. Various private and public entities provides financing and rebate incentives for buying a new HVAC system.

One of the best ways to raise the value of the house is by upgrading the home with new furnace-air conditioner. One of the great reasons for updating is to conserve energy. Preserving the energy which is used each month can substantially help to lower the utility bills. Helping to save the homeowner money on utility bills and enhancing the upfront market value of the house are just two of the benefits of installing a new HVAC system.

Many houses presently have older HVAC systems that use a refrigerant known as R22 refrigeration and this is used to chill out the air passing in the room. R22 is known for depleting the ozone layer. In order to ban all R22 refrigerants from further depleting the ozone, the government passed new laws which were made mandatory for all the new air conditioners that were being installed to use only a new refrigerant named R-410A. This R-410A refrigerant is costlier but is effective in not harming the ozone.

Houses are generally operating at around a 70-80% rate of efficiency which implies that 70-80% of the energy is used to run the furnace in the house and the rest 20-30% is wasted. At present times most of the furnaces that are being installed are 90% better or more efficient which implies that 90% of the energy is consumed, which in turn can help to save large amount of money over the entire lifetime of the home furnace due to less waste.

Updating the equipment is a good method to improve a home but it does require upfront cost. First there is the cost of the new HVAC system. This cost can range between $750 -$3000 depending on the brand, size and the model. The average cost for a new furnace is approximately $1,400 for the unit and includes no other elements costs which are used for installing the furnace. The price of a new air conditioner is between $600-$3,000 which depends upon the brand, model and size. The average cost for a new air conditioner for a 2 bedroom / 1 bath house is approximately $1,200 which is just for the unit and does not include any installation costs. The coil of the new furnace costs around $300- $600 and that of a new air conditioner costs approximately $400.

When it's time to get a new HVAC system, price is always an issue. It's important to do your homework, ask lots of questions and get at least three quotes from reputable HVAC contractors.

Forced Air HVAC Systems and Older Homes


Although a forced air HVAC system has long been a staple of modern construction practices, a significant number of older homes are without a forced air HVAC system. In some cases, older homes lack forced air as a matter of negligence. In inner cities, once grand homes have sometimes been chopped up into gritty apartments after an area of town went from riches to rags. But in other cases, well cared for older homes lack forced air systems because their owners are dedicated to preserving their homes' historical splendor. If you own an older home that lacks forced air and you prefer to keep it that way rather than tarnish its historical integrity, your position is understandable. But it's also worth considering the benefits that can come with retrofitting an older home with a new HVAC system, and can come without compromising your home's original aesthetic.

The Aesthetic and the Ugly

Even in new homes, HVAC elements are often implemented in such a way that they look like a necessary evil of modern living. Dull air vents peer up from floors and out from walls, basement ceilings have clinical ductwork that runs their expanse and antiseptic air vents cling to walls. So, why should you introduce these elements into a beautiful home that was built in a time when home builders cared more about quality than quantity? You shouldn't, and you don't have to; at least, not when you consult with a heating and cooling company that has experience retrofitting older homes with forced air systems. Far from having to implement unsightly air grates, ductwork and thermostats, the right HVAC company also provide you with aesthetic solutions the preserve the look of your home. For example, air vents can be placed in inconspicuous locations, thermostats can be placed in closets and you can also opt for ductless air delivery.

Cost Effectiveness

While you might be showing your home love by not submitting it to modern heating and cooling installations, it won't return that love in the summer when you have to cool it with window units. Instead, you'll be paying electric bills that are far higher than you would if you implemented forced air components. Despite the historical beauty of older homes, most of them were designed at time when concerns about energy efficiency were in the far off future, meaning that their windows and doors were designed to let in light and keep out the roughest aspects of the elements, and that's it. Therefore, installing an highly energy efficient central air conditioning system can allow you to keep your beautiful doors and windows and still not pay excessive electric bills. In addition, implementing a forced air system that respects your home's aesthetics can actually improve its aesthetics, as it allows you to do away with unsightly window units.

The Basics of Heating and Air Conditioning


Heating and air conditioning are two things that many modern homeowners can't do without, but what many homeowners don't spend much time thinking about is how this complex system keeps them warm in the winter months and cool in the summer months.

When talking about home heating or anything related to air conditioning, you could be referring to any device that provides your home with either hot or cold air in a given situation. In recent years, there has been a rise in the devices available to homeowners to not only keep them comfortable, but be more efficient while doing it.

This increased efficiency is a good thing to have simply because they deliver the same level of either hot or cold air into the home while, at the same time, using less power. This lowered power consumption means that your utility bills will be lower because you aren't using as much gas or electricity in order to keep these devices operational.

The heating side of heating and air conditioning deals with devices like gas or electric based hot air furnaces, electric heating systems and boilers in order to keep a family's home warm when the temperature outside drops.

No matter what kind of system your home uses to provide warm air, it's important to keep the system running at all times. By resorting to preventative maintenance, you not only dramatically lower the chance that some unforeseen issue will happen, causing your home's heating to die out just when you need it, but you can prolong the life of the system as well.

Regularly scheduled maintenance on your home's heating system can include performing tasks like checking the compressors and coils for leaks, cleaning the coils if necessary and replacing air filters. Beyond these things, you can also increase the life of your heating system by making sure that all motors and fans are working properly.

Another important aspect of heating and air conditioning maintenance is to make sure that all wiring and controls are functioning properly. Those that aren't could short out and damage the whole system. Heat pumps and exchangers are two other important components of your heating system that should be checked and maintained regularly in order to assure that the system is working at maximum efficiency.

Many of the same rules that you would follow in heating maintenance apply to air conditioning maintenance as well.

Components like humidifiers, air cleaning systems, programmable thermostats and outdoor condensers make up the cooling half of heating and air conditioning and their job is to see to it that you don't have to suffer through the months of summer when temperatures outside rise.

Because some parts of the air conditioning system, like the condenser, are outside of the house, maintenance involves protecting your system from the elements. In that respect, part of your preventative maintenance routine should involve checking the unit for things like branches and leaves that can fall into it.

While there are a number of different things that you, as a homeowner, can do to make sure that your heating and air conditioning systems run as they should, never hesitate to get in touch with a professional if there's any aspect of maintenance that you think might be too difficult for you to handle.

Installing a New Air Conditioning Unit


Are you tired of the summer heat? Are you having a difficult time sleeping because your home is too hot? Is your electric bill too high because of all of the fans that are running? If so, then it might be time for you to consider installing a new air conditioning unit. There are a few things that you can do to make sure that the installation of your new unit goes smoothly. The first thing that you should do is to prepare your home for your new unit. Then, you should do everything you can to make sure that the installment day goes smoothly. Finally, you should sit back and enjoy your new, comfortable home.

Prepare Your Home

The first thing that you can do to make your air conditioning installation go as smoothly as possible is to prepare your home for the new unit. The best way to do this is to make sure that you check your home's insulation. It is important that your home is well insulated, as this will help your new A/C unit to run as efficiently as possible. The last thing that you want to do is to spend money on a new unit only to have the cold air leave your home due to lack of insulation.

Installation Day

After you have prepared your home for the new air conditioning unit, you should begin preparing for the installment day. If you are installing the unit yourself, then you should make sure that you have read all of the instructions and turned off the relevant utilities. You should also take care to ensure that you have all of the tools necessary. If, on the other hand, you are having a professional install the unit, then you should make sure that you have cleared the area around the site so that the technicians will be able to have adequate access to everything that they need.

Enjoying Your New Unit

Finally, after you have prepared your home and installed your new unit, all that is left to do is to sit back and enjoy your new air conditioning system. Air conditioning can make a hot, steamy summer much easier to tolerate. When installing a new unit it is important that you prepare your home for the new system and stay well prepared for the installation day. This will help you to be able to enjoy your new unit and the comfort that it brings.

Ducted Air Conditioning is an Efficient Way of Heating Or Cooling Your Home


Ducted air conditioning is one of the most efficient ways to heat or cool your whole home however it is not the cheapest, when considering air conditioning for your home, cost is always an important consideration we all like to save money were ever possible. There are several different types of ducted air conditioning below I will give a brief summary of each. The choice of which type best suits your needs really depends on where you live and your life style.

Ducted evaporative cooling is well suited to a hot dry climate like Australia or south Africa and is very efficient at cooling your home. A basic description of how evaporative cooling works is, the hot outside air passes through the wet filter pads of your evaporative air conditioning unit which is mounted on a metal dropper located in a central position with in your home. The dropper has several lengths of flexible ducting connected to it which distributes the air through out your home and into each room which has a outlet. One of the disadvantages of ducted evaporative cooling is it does not heat your home.

Ducted Heating is great for the colder climates and is an efficient way of heating your home in places like USA,Canada and the east coast of Australia. A basic description of how ducted heating works is the cold air is drawn through the heat exchanger of a gas furnace unit which is mounted in a central position with in your home. The gas furnace has lengths of flexible ducting connected to it which distributes the warm air through out your home and into each room which has a outlet. the unit will then recirculate the warm air and repeat the process. One of the disadvantages of ducted heating is it does not cool your home.

Ducted reverse cycle air conditioning would be one of the most popular systems as it heat and cools your home. Like the other two systems it has flexible ducting running through out your home to various outlets, depending on the size of your home and the design you can heat or cool the parts of the home you are using.

Energy Efficiency - Easy Ways To Reduce Your Air Conditioning Use And Save Money


Did you know that 14% of the energy produced in the United States is used to air condition buildings and 10% of the energy produced is used to air condition homes? What is the total cost to consumers? Over 15 billion dollars a year. To put that into perspective the American Council for an Energy-Efficient Economy (ACEEE) equates that to an astounding 140 million tons of CO2.

Energy efficiency refers to the reduction of energy used by specific end-use devices and systems, such as air conditioners, typically without affecting the quality of the services provided. Energy efficiency can be achieved many ways. In the case of your air conditioning one simple way to achieve this efficiency is by reducing your air conditioning needs.

Reducing Your Air Conditioning Needs

Depending upon where you live you may feel very dependent on your air conditioner. You may even be thinking about upgrading to a newer air conditioner with higher improved SEER (Seasonal Energy Efficiency Ratio) but before you do consider the following - the easiest way to save money and energy on cooling is to reduce your air conditioning needs in the first place.

While some of my solutions may seem initially costly - in the long run you will enjoy a monthly energy savings, in some cases you may appreciate the value of your home, and you will always feel good knowing that you are doing your part to fight global warming.

Strategies for Reducing Your Air Conditioning Needs



  • Invest in alternate forms of in-house cooling such as ceiling fans or house fans. Unless you live in a very humid climate than ceiling fans, which can provide cooling by creating a low- level "wind chill" effect, are a good and relatively inexpensive choice. Ceiling fans are also rated by Energy Star so it's easy to find energy efficient models. House fans are usually large fans in your top-floor ceiling. They cool by expelling hot air out and in-turn creating a vacuum that sucks cooler air in. Unfortunately house fans are not covered by Energy Star. In either case fan use substantially less energy then air conditioning systems and can go a long way in reducing your dependence on your air conditioner.


  • Replace older single pane windows with newer more energy efficient double pane or even triple pane windows. More energy efficiency windows can reduce your air conditioning needs but depending upon the number of windows involved it may get expensive. If expense becomes a concern you can always opt to use drapes or window coverings that block out the sunlight effectively. While drapes and window coverings will help, for the best results when justified, I recommend replacing the framing and glass. In some cases replacing your windows can improve their energy efficiency by up to 41% in the summer - when your air conditioning is used most.


  • Consider shade gardening. If replacing your windows is expensive but you have room for gardening consider planting shade trees on the sunny side of your home. The less direct sunlight that gets into your house, the less heat. Shade trees also have the added benefits of reducing local area CO2 pollution. You can expect a full grown shade tree to gradually remove about 10 lbs of CO2 a year, native trees are always good choice because they are easier to maintain.


  • Replace non-programmable thermostats with programmable versions. You can save as much as 10% a year on your cooling bills by using a programmable thermostat to adjust the temperature automatically while you regularly sleeping or out of the house. When you shop for a programmable thermostat, be sure to look for the Energy Star versions.


  • Install energy efficient roofing. Energy Star offers a number of different Reflective Roof Products that can reduce your peak air conditioning demand by as much as 10-15%.


  • Use light-colored or "cool" sidings or paints with a high Light Reflective Value (LRV). Most major paint manufacturers can tell you the LRV of any color paint chip. The higher the LRV the more the paint will reflect away heat instead of absorbing it. Keeping your house cooler by reflecting away heat will reduce your air conditioning needs.


  • Replace your older/inefficient appliances such as old or secondary refrigerator or, replace incandescent light bulbs with LEDs. The less heat your appliances and inefficient lighting give off the less your air conditioner will have to compensate.


  • Unplug large consumer electronics when you aren't using them. Lots of newer electronics have a "sleep mode" that keeps them ready for action. This "sleep mode" uses electricity and because the device is running at some level it will still be creating heat. When not in use,don't forget to unplug chargers for your smaller devices, too


  • Properly insulate your home. If you have a home that isn't properly insulated you can waste a lot of electricity when the cool air created by your air conditioner escapes. Why? Your air conditioner will simply keep working harder to maintain a stable temperature regardless of continuous air leaks. The harder your air conditioner works the more electricity is uses and the more expensive it becomes. If your home has an attic it is very common for air leaks to occur between your living space and the attic space.

An easy way to save money on air conditioning which is often overlooked is through the simple reduction of its use. While enjoying the cool benefits of air conditioning it is easy to overlook its expensive nature, due to the electricity required one has to also consider it's environmental cost. While being green isn't always easy, in this case, being green will save you money - by reducing your energy usage.

Heating And Air Conditioning Efficiency


Heating and air conditioning efficiency is all about getting your heater and air conditioner to run less. Not only will it save you money on your utility bills, but it will also make the equipment last longer and cost less to maintain, saving you even more money. In addition to the monetary benefits, heating and air conditioning efficiency is also good for the environment. The less you let the heat and air conditioning unit run, the less energy you use. By using less energy, less energy has to be produced, which means less carbon emissions. Carbon emissions are what destroy the ozone layer and lead to huge problems like warming of the earth. So we know that using your heater and air conditioning less is a good idea, now its time to find out how to accomplish this goal.

The first way to make your HVAC systems run less is simple and free. It's simply to set your thermostat based on the season. Most energy experts say that it's best to set your thermostat on 78 in the summer and 69 in the winter. This means your system will run less because the temperature you set is closer to the outside temperature. This method is free, but if you're like most people, you'll forget to change the setting regularly. So an inexpensive option is to buy a programmable thermostat. For around twenty dollars, you can get one and easily install it yourself. You can even program it higher while you are away, saving you even more money.

The next best way to improve your heating and air conditioning efficiency is to install and replace insulating materials in your home. It's always a good idea to upgrade your insulation or change it if it's old. Not only will you save more money, but as an added bonus you can actually get a nice tax credit for making the switch. Another great thing to do is caulk the windows and doors. Replacing worn caulk or adding new caulk is like shutting an average size window in your home. You can also install window film on your windows. Window film blocks sunlight out and keeps the temperature in your home lower in the summer. All of these things combined can add up to a nice savings as well as a substantial tax credit.

The last thing you can do to improve the efficiency of your heating and air conditioning system is to have them regularly maintained and "tuned up." Keeping your system properly maintained helps it to run easier and kick on less. Not only does this help you save on your power bill, but again, it allows you to save money by not having to replace the system components as frequently.

With a little bit of money and some planning you can drastically reduce your heating and air condition expenses. It's good for you and the environment.

Air Conditioning or Evaporative Cooling?


If your home or office is too hot then it's very important that you use some kind of air cooling device in order to reduce the temperature and to allow you to continue to work and play without feeling too hot and without being distracted by oppressive heat. At the same time this can help to increase your alertness and energy levels and it can help to prevent problems such as dry skin and headaches.

But if you decide to implement a new cooling device you will find that you have multiple options, and specifically you will be able to choose between air conditioning and evaporative cooling. Here we will look at what the difference is and what evaporative cooling actually means.

What is an Evaporative Cooler?

An evaporative cooler is also something called a swamp cooler or a desert cooler, and it works (as the name might suggest) via the evaporation of water in order to cool the air. This will then work by transitioning liquid into water vapour and releasing it into the air, and the main benefit of this is that it takes significantly less energy in order to accomplish when compared to refrigeration - particularly in very hot climates which makes it highly suitable for very hot and dry rooms.

At the same time evaporative coolers have the added benefit of course of increasing the amount of moisture in the air. This can be very good for occupants, not only helping breathing and preventing skin problems, but also improving their comfort. Of course this requires a water source in order to operate.

The downside of an evaporative cooler however is of course that it can sometimes create too much moisture if the environment is already quite moist. For instance if you should be in a property that has problems with mold and with leaking, then using an evaporative cooler may in fact worsen this problem resulting in dank and wet air - which can also cause various health problems.

Air Conditioning

Air conditioning can use multiple methods such as vapour-compression or an absorption refrigeration cycle. The latter is more common, and this works by sucking the air in using a slight vacuum, then moving it around a cool area before dispelling it once again. This process then cools the air without increasing moisture, and normally the air will be taken through a filter and possibly treated in other ways. This has the big advantage of not altering the moisture levels in the air, and at the same time it is also useful in that it can be used to clean the air of various unwanted particles and bacteria thus helping to prevent the spread of disease, and also helping to keep the air and the property much cleaner.

The downside to air conditioning is of course that it uses up a lot of energy comparatively as a lot of energy is needed to cool the air that much. Furthermore, if your property is very dry, this can actually increase the dryness in the air and cause problems as a result.

Fixing Common Thermostat Problems


Most homeowners have little HVAC knowledge beyond using the thermostat. If your thermostat fails, many people end up calling a Denver HVAC company thinking there is something wrong with their air conditioning equipment when in reality, there is something wrong with the thermostat. When the AC refuses to turn on, it can be hard for someone who is not an HVAC expert to determine if the problem is in the equipment or in the thermostat.

However, before you call a Denver HVAC company, try and follow this troubleshooting guide to see if you can get to the root of the problem. Even more advanced digital and zone-control thermostats really just function as thermometers that switch the HVAC system on and off depending on the temperature. As an electronic switch, the thermostat needs to be hooked up to power in order for it to work and communicate with the heating and air conditioning equipment.

Usually the power for the thermostat comes from the air conditioning unit itself. So any break along this line could cause the thermostat to turn off. You can check the circuit breaker in the air handler or heating split system to see if it has flipped off. Sometimes the handling unit also has a power switch outside the unit that looks like a light switch. Some digital thermostats have two different power sources: battery and wired from the external unit. The batteries power the display, so if the batteries go out, the display stops working but the ac unit does not stop cooling. You can save yourself a lot on calling a Denver air conditioning repair company by simply replacing the batteries. The batteries are there to maintain your programmed thermostat settings in case the power goes out.

If the problem with the thermostat is not the power, it could be the location the thermostat is installed. Except in very advanced models with multiple temperature sensors over the building, most thermostats have the thermometer built in. That means if the thermostat was built into an area that does not represent the air temperature in your home then it will give false readings.

Thermostats with mercury bulbs need to be level to give accurate temperature readings. Heating anticipatory can also get out of whack when not properly calibrated. The anticipatory needs an amp meter in mechanical thermostats to adjust to make sure it properly keeps the blower running past the burner time to get excess hot air out of the ducts.

The Keys On How To Successfully Promote Healthy Hair Growth


The key to hair growth is hair follicle stimulation. Increasing blood flow to the scalp and making sure that your hair is healthy should encourage strong, shiny and thick growth. Various vitamins and minerals promote hair growth by adding nutrients and stimulating the follicles. Some of these vitamins can be ingested and some can be sprayed on the hair. Vitamin B, for example, is said to be extremely effective for improving the quality and quantity of hair -- maybe as much growth as twice the normal rate! It is a simple treatment that can give you the healthiest, shiniest hair you have ever had!

Sometimes a dermatologist may recommend special medicated or herbal shampoos that help with hair growth. Either should be safe for your hair, but it should be assumed that medicated treatments are to be used with special care. Whenever medications are concerned, it is important to carefully follow directions indicated on the label. These types of shampoos vigorously stimulate the scalp to promote quick hair growth. Ask a doctor or dermatologist if you are interested in this more aggressive hair growth treatment.

Everyone should use a good hair conditioner as well. This will help protect the hair by preventing breakage due to styling, dry air and other harsh conditions. Conditioners also help keep the skin on your scalp healthy and prevent irritation that might interfere with healthy hair growth. A conditioner will also help the hair itself feel good and look nice and shiny. Hair that has been conditioned is easier to comb and easier to style.

Perhaps the most important thing you can do to promote healthy hair growth is to eat right and drink plenty of water. In addition, make sure that you have a balanced diet that includes lots of fruits and vegetables as well as at least one good source of protein every day. This will make your whole body feel good and it will do amazing things for your hair!

How Does Air Conditioning Work?


How often do you drive past a home or other building and notice the air conditioner? Probably never, unless it is a window air conditioner that looks like it doesn't belong there. True air conditioning means not only controlling the temperature, but reducing the humidity and purifying the air. Air-cooling is simply forcing cool or cold air into a room, space or building. For the purpose of this article, the terms will be interchangeable. The simplest way to describe it works is the same way your refrigerator keeps food cold.

That would be a fair enough explanation, if you know how a refrigerator keeps things cool. You do know that almost everyone has a refrigerator. You know they make a very quiet noise every few minutes. You know things stay cold and fresh longer. The refrigerator isn't that complex. It circulates a refrigerant through a system of coils. The noise you hear is a compressor. The compressor compresses the gas refrigerant into a liquid. The liquid then moves through the coils and absorbs heat. We will go into greater detail shortly.

Many homes have air conditioner units in the back or side yard. Some have the window air conditioner, which is effective for cooling a smaller area. Office buildings and other larger buildings have the units on the roof or in large metal structures containing a system.

No matter what the size or the shape, most all air conditioners function the same way. As we said, it works essentially the same as your refrigerator. The principal is evaporation. Both the refrigerator and the air conditioner unit use a refrigerant that, in its normal state, is a gas. The gas may be one of several types or composition, but it is commonly referred to as Freon. The process of cooling the inside of a refrigerator, or for an air conditioner to cool a building space, is a cycle.

The first piece of the air conditioning system is the compressor. The compressor does just that, it compresses the refrigerant gas. The process makes the refrigerant become hot and, of course, under pressure. The now hot gas circulates through coils on the outside of the refrigerator or building and dissipates the heat. The heat dissipating cools the refrigerant gas back into a liquid. After the refrigerant becomes a liquid it goes through another piece of the system called an expansion valve. Running through the expansion valve produces evaporation and the refrigerant becomes cold and at low pressure. The cold gas continues through the interior of the refrigerator or building via coils. The cold, low-pressure refrigerant attracts and absorbs heat inside a refrigerator. In an air conditioner, a fan propels the cold air throughout the area or building. The cycle starts then all over again.

There is little doubt that most people look at air conditioning and air cooling as a welcome miracle. It is a simple process of converting a refrigerant gas to a hot liquid under pressure, then changing it to a low pressure-cooling agent to absorb heat; keeping us and our food cool.

Ductless Air Conditioning Systems


There are several different kinds of air conditioners on the market today. For instance, a ductless air conditioning system is one that has been around for several years. They are most common in larger homes as you would not need this type of two part system for a smaller home, or just in a single room.

When summer hits you will see a lot of people setting up their small conditioners in windows, or on ledges. An conditioner is a wonderful household appliance that has been around for over 70 years. These incredible inventions do so much more than just keep the house cooled during the hot, steamy days of June, July, and August. When the temperatures get high, the humidity (or the amount of moisture that is in the air) also rises. This makes the heat feel like a sauna. You sweat more. You have a hard time doing activities. And people with respiratory problems can have serious side effects because of it. An conditioner keeps the temperature comfortable, but also decreases the humidity in your home.

Ductless air conditioning systems are a great alternative to small portable air conditioners, and even central air and heating systems. A duct less air conditioner is really a mini split system that has two separate parts connected by tubes of refrigerant. This type of conditioner is great for a smaller home with not a lot of square footage. A ductless system should not be confused with the window type small portable air conditioners. Think of this type of air conditioning system like what you would see in a hotel room or school building.

The main system is the part that sits outside the wall. This unit houses the condensers and refrigeration where the air is cooled through the fins and the blower. It sits on the ground in a level area. Connected to this part of the system is the part that looks like through the wall air conditioners. They can sit on a window, but they are much better situated through the wall itself. They have more stability and are not to be moved after they are installed.

Keeping your home cooled down, and the humidity at a comfortable level, the ductless system is much more efficient that a window type conditioner. This type of system works with a thermostat that you can control from either the control panel on the conditioner face, or through wall mounted thermostat. Ductless air conditioners are great for creating an environment that is not cold, but a constant cool level. Instead of just one room that is colder than the rest, you have several rooms that are all kept at a comfortable temperature.

The main advantage of a ductless air conditioning system, however, is that you do not have to worry about storing it in the winter. You simply cover it up for the winter months and seal it off from the elements. This saves a lot of work trying to lift a system up into the window. When you are thinking about a way to keep your home cooled with next summer season, look into the ductless system.

How Do Air Source Electric Heat Pumps Work?


Air source electric heat pumps are usually heaters that are used in moderate temperatures, as opposed to freezing cold. These are also heaters best used for homes where there are fewer cold days and milder winter weather in general. As you can tell by the name, these types of pumps do use a heavy amount of electricity. The advantages of air source electric heat pumps lie in this technology's energy efficiency. Energy efficiency means that you as a consumer pay less per month than other technologies such as dual-fuel heat pumps or geothermal heat pumps.

The major disadvantage with this type of technology is that it has a relatively high cost at first due to equipment you have to purchase. However, in the long run these pumps tend to be the least expensive to maintain. Besides price, another drawback to be aware of with air source electric pumps is that they cannot function in all types of weather, as effectively as the two other technologies can.

The heat produced by this technology of system can be compromised whenever the temperature outside reaches -90C. In addition, high winds can sometimes affect performance. Usually, experts recommend that you keep a backup system ready just in case you get inclement weather that disturbs the air source electric pums system.

Nevertheless, these pump systems do offer reversal systems with air conditioning. Therefore, they are popular for mainstream homeowners. These systems use the difference between outdoor air temperatures as well as indoor temperatures. Historically, these systems are easy to learn and install for the average consumer. Their limitations are intrinsic to the design. They use the outside air as a heat source. Therefore, the higher temperature differential (thanks to extremes in temperature) will lead to a lower quality performance.

Top manufacturers of air source electric pump systems include Amana, Carrier, Goodman, Rheem Classic/Prestige and Ruud. For example, one of the products (the Aire-Flo 13 SEER Heat Pump) comes with a corrosion-resistant cabinet with drain holes and a quiet running compressor. The system has a 30-60-90 adjustable time defrost feature. It has a capacity of one and one half tons to five tons.

Another air source electric pump system to mention is the Friedrich M09YF, a unique product and one less expensive than others because it is made ductless. Other options include a wireless remote and 24-hour timer.

You can find supplies for these air source electric heat pumps online for a low price.

How to Service an Air Compressor by Excel Compressors


Compressors are expensive units and such an investment must be kept in excellent working condition. Air compressor servicing should be part of all maintenance schedules. As an owner of an air compressing unit, it is essential to start off on the right foot. One should invest in a properly working compressor. The apparatus needs to be of the correct standard. Units should have an ASME (American Society of Mechanical Engineers) certification. This certificate proves that the right materials and workmanship is used during the construction of the unit.

Once this is properly secured, it is time to move on to servicing of the unit. Avoiding a problem has always been a recommended cause of action, as opposed to treating the problem. Servicing the unit will see to this. When using an compressor, make sure that the right air pressure is maintained in the cylinder. This can be achieved by cleaning the clogs to avoid corrosion and clogging within the compressor engine.

Another area that requires keen attention during the servicing of an air compressor is the gauges. These keep track of vital functions of the compressor. If one of them is faulty, chances are that eventually, the unit will give up. In extreme cases, bodily harm can be caused by faulty air compressors-when excess pressure builds up and results in an explosion. When servicing the unit, the oil levels of the gauges, accuracy levels of the cylinder pressure gauges and the pressure regulator should be checked out. All of them should run properly to ensure not only the sustainability of the compressor, but also the safety of people operating the unit.

Oil levels are the next step when servicing compressor units. The right oil levels are required to ensure proper lubrication of its engine. This can easily be done with the right apparatus. However, professional air compressor repair crews should be consulted here. Checking oil levels is a delicate procedure that requires in-depth know how combined with a high level of experience.

The filters are another component that needs checking. Running water should be used on these air filters to remove any dirt. Before attaching the filters back on, they should be dried thoroughly to ensure they function properly. It is not uncommon for people to try compressor servicing by them to save on money. However, it is always wise to contact an expert before you get a solid grip on the whole procedure.

Air Conditioning Inspections and Energy Use


Air conditioning inspections are a vital part of business planning for building owners or managers. Air conditioning inspections aren't just a legal requirement, but they are also an important element of your ethical responsibilities.

We all know that the environment is suffering from the impact that humans have made - by having a TM44 report carried out on your systems, not only will you keep trading standards at bay, but, more importantly, these reports can also help you to keep a check on the energy performance of your air con systems. This makes this type of inspections crucial if you want to reduce your carbon emissions and, in turn, do your bit for the environment.

TM44 reports are the only way to check how your air con systems are performing from an efficiency point of view. Without a report, you will have no idea if your systems are eating their way through a disproportionate amount of energy. Every unnecessary unit of energy that your air conditioning systems are using is a unit of energy that is wasted and ultimately has a detrimental effect on the world around us.

Air Conditioning Inspections and Your Corporate and Social Responsibility

With the potential environmental crisis featuring more regularly in the news with every passing week, the need for these inspections becomes ever more apparent. Every single one of us has a vested interest in reducing our carbon footprint, and for businesses, this interest is magnified - it is important that you can demonstrate to both your staff and your customers that you are taking your corporate and social responsibility seriously and air conditioning inspections are one way to evidence this.

Corporate social responsibility is becoming more and more important to businesses - while your corporate social responsibilities cover many different factors, carbon emissions and the fight to save the environment should fall somewhere near the top of the list. The need to reduce carbon emissions applies more strongly to businesses than individuals - what one person can save energy-wise with a little bit of planning and effort can be multiplied several fold for big businesses and companies - while every company is bound by the same laws regarding these inspections, the bigger your business premises, the more energy use, your TM44 inspections can help you save.

How Air Conditioning Inspections Can Help

These reports must be carried out by a qualified assessor, according to TM44 guidelines. They will help to identify any areas for improvement and to make sure that your systems are running at their most efficient. These reports will show your energy use and provide recommendations for improved efficiency.

As well helping you to stay on the right side of the law and meet your corporate social responsibilities, these inspections can save you money in two ways. By having a report carried out, you ensure that you are not at risk of a fine for non-compliance and, as air conditioning inspections and reports show you how you can reduce your energy use, you will be able to save money by not using energy unnecessarily.

The Importance of Air Conditioning Maintenance


If you own a central air conditioning unit, it is important to perform regular maintenance on it. This is something many homeowners neglect to do, often resulting in high repair bills. Many people see repairs as useless or a waste of money. In fact, the complete opposite is true; if you perform regular maintenance, you might be able to save money on future repair bills.

Higher Utility Bills

When your air conditioner does not run efficiently, you will have much higher utility bills than is necessary. The harder your unit has to work, the harder it is on the air conditioner and on your utility bills. If you start to notice your utility bills are higher than normal, this could be a sign your AC needs maintenance or repair.

Filters

The air filter is often a major culprit in an inefficient air conditioner. If you do not regularly change your filter, it has to work harder to get through the dirt and debris that has collected on the filter. Most filters need to be replaced every one or two months unless you purchase a higher quality filter or one that filters out special allergens. If this is the case, you should follow the directions of the manufacturer to ensure your unit runs properly.

Clear the Area Outdoors

Periodically check the area around your air conditioning unit. Any large weeds or collection of leaves can obstruct the air flow coming from your AC unit. Take extra care to determine no leaves or weeds are stuck in the coil because this is what causes the air to run inefficiently. Once you are sure the area is clear, you can also clean the air outlet on the front of the unit to ensure air flows freely.

Check for Rust

An air conditioning unit that is full of rust will not work as efficiently as it should either. Sometimes you can take care of the rust on your own with a steel paint. If the rust spots are large or you feel the rust is affecting how your unit runs, it is best to call for professional service to ensure your unit is still safe to use.

Regular maintenance on your air conditioning unit is important to its effectiveness and longevity. It only takes a short amount of time to change the filter, inspect the unit, both inside and outside, and clear away any debris. These simple actions could save you hundreds of dollars in the long run.

Why Air Conditioner Service Is So Important


The best way to keep an air conditioner running at peak performance is to have it serviced regularly. Many people do not realize the importance of air conditioner servicing until it is too late. Servicing an air conditioner does not take a great deal of time or money, so it is something that everyone should have done, whether they have a window air conditioner or a big central air unit. With regular maintenance, an air conditioning unit can keep its owners comfortable even on the hottest day. There are many other benefits of regular maintenance too.

One great benefit of regular air conditioning servicing is saving money. When an air conditioning unit is running at its best, it does not use as much energy. In the long run, this can save hundreds of dollars a year on cooling costs. The money saved will outweigh the service charges, so it is definitely something that should be done at least once per year. Servicing also saves consumers money because it makes their air conditioning unit last longer, meaning it will not have to be replaced as often. Not to mention the fact that it also prevents other expensive damages.

Regular air conditioning servicing also provides safety benefits to those dwelling inside the building. It prevents many hazardous conditions from occurring. It also reduces the amount of dust and bacteria in the air. Most service technicians will also test for carbon monoxide in the air, which is a very dangerous chemical. If any carbon monoxide is found, they will be able to stop it quickly, making a home or place of business much safer to be inside.

In addition to the money saving and safety benefits of air conditioner servicing, there is also the benefit of saving time. People who have their air conditioners serviced the way that they should do not have to spend time looking for contractors. They are also far less likely to have to sit in the heat while they wait for expensive repairs to be done. All of these benefits are reason enough for anyone to have their air conditioner serviced on a regular basis.

Reliance Home Comfort Heat Exchanger Review


Heat exchangers are an essential part of any furnace. Put simply, they work by heating and transferring warm air from your furnace to your home. They're typically made out of some type of metal, and work by separating the air from the heat source in the furnace.

Sometimes they will crack, either because they have been installed improperly, damaged during shipping or from running the furnace at higher temperatures than it can handle.

A cracked heat exchanger in a gas furnace can be extremely dangerous and should be fixed immediately. The main risk is carbon monoxide, which can get into the air in your furnace and can be pumped throughout your home. Colourless and odourless, carbon monoxide is a poisonous gas that can be a silent killer.

You should have your gas furnace inspected regularly. Homeowners should also watch for any changes in the colour or activity of the flame in your furnace's blower. If it changes colour or flickers unusually it could be an indication that there is a crack in your heat exchanger.

In choosing a furnace, you should consider the type of heat exchanger as there are several brands to choose from.

The most well-known are Goodman, Rheem, Amana and Carrier.

Owned by United Technologies Corp., which also owns Pratt & Whitney and Sikorsky, Carrier is the largest manufacturer of heating and air conditioning systems in the world.

Carrier furnaces use both stainless steel and aluminized steel heat exchangers, which are covered by a limited lifetime warranty, and have an Annual Fuel Utilization Efficiency (AFUE) Rating of up to 96 per cent and above.

The AFUE rating tells you how much energy in your furnace is actually being converted into heat. So an AFUE rating of 96 means 96 per cent of the money you spend running your furnace goes to heating your home, while the rest escapes as exhaust. The industry minimum standard is 78 per cent.

The second-largest manufacturer of HVAC systems is Goodman, based out of Houston, Texas. The company boasts a lifetime warranty on its dual-diameter tubular heat exchangers and an AFUE rating of up to 95 per cent.

Goodman also manufactures Amana brand furnaces after acquiring the company several years ago. Amana furnaces offer a similar dual-diameter tubular heat exchanger and lifetime warranty, along with 95 per cent AFUE rating.

Owned by Paloma Industries of Nagoya, Japan, Rheem's most advanced gas furnace uses two heat exchanges to capture hot vent gasses and use them to pre-heat household air. Its furnaces come with an AFUE rating up to 95 per cent and a limited lifetime warranty on heat exchangers.

Whatever brand you choose, make sure you use a qualified company to install the system, as installation is a key component to ensuring your HVAC system works properly and doesn't cost you money in lost energy. A system that has been improperly installed is one of the main reasons why your heat exchanger may crack.

Heat Pump Ratings: What Are SEER, HSPF and AFUE?


When checking out heat pump ratings, most people encounter words like SEER and HSPF. Most say that the higher they are, the better would it be for the user, but how exactly does this work? Considering that SEER and HSPF are basically unknown quantities to the buyer, most individuals don't really think of this as a big factor when making their purchase. However, this is a very wrong thing to do since these rating codes factor very largely in the efficiency of the model.

That being said, following are the explanations behind ratings and how buyers can choose a model while referring to these numbers.

Seasonal Energy Efficiency Ratio or SEER

This rating basically refers to the cooling capacity of the equipment. This is the amount of cooling output a unit produces for every watt of energy it consumes. Hence, the goal here is to have the highest cooling output possible while eating up as little energy as possible. Currently, the standard rate for SEER to be considered energy efficient is around 13 but anything higher than that is considered better. The good news is that new models all have SEER heat pump ratings higher than the prescribed amount. As for those who are using older product versions, it might be best to recheck their SEER capacity as a low one would mean a huge amount of energy wasted.

Heating Seasonal Performance Factor or HSPF

The opposite of SEER, the HSPF refers to the warming capacity of the pump. Just like SEER, it refers to the overall output of warmth by the unit divided by the total amount of energy it eats up during a certain period of time. The best models are those with the whopping HSPF rating of 10 although most models today boast of around 7.7 HSPF. Hence, be very wary of the purchase and try to find a model between 8 and 10 heat pump ratings. Just like SEER, higher means better. For those with models that were made prior to 2005, it might be best to change their heat pumps now as their ratings are bound to be lower than the standard 7.7 which was enforced the same year.

Average Fuel Utilization Efficiency or AFUE

As the name suggests, it's the amount of fuel the unit uses in order to heat up a home. The fuel heat pumps rating is basically provided in term of percentage with higher amounts considered better. It's actually pretty simple to see how it works out. For example, a unit with a 70% AFUE rating basically means that 70% of the fuel is used for heating and the other 30% is wasted fuel. Hence, those who have AFUE's of around 60% should start thinking about changing their particular unit since they're practically letting their cash be burned off.

Currently, there are heat pump ratings for AFUE that go as high as 90% or more. With this type of AFUE ratings, one will find that their utility bills would greatly decrease over the next years of its use.

Hospital Air Conditioning


Retrofitting a Hospital Air Conditioning System

Hospital HVAC design is a complex matter to begin with. When you attempt to retrofit a hospital air conditioning system while a hospital continues to operate it becomes increasingly complicated. Special attention needs to be paid to areas where construction and renovation are taking place to ensure the health and safety of patients is not put at risk.

The new hospital design should account for potential disruptions to power and water during construction. It should also account for the presence of dust and air born contaminants that are invariably part of any renovation. Efforts need to be taken to minimize the presence of infectious contaminants that could threaten the health of patients.

Taking Proper Hospital HVAC Design Precautions

Retrofitting a new hospital air conditioning system can involve the demolition of walls or other internal structures that can pose particular dangers. If not properly coordinated it can lead to the disruption of critical hospital functions. The demolition and removal of an existing hospital air conditioning system can also introduce contaminants into the air. Your HVAC hospital design team needs to work closely with the hospitals infection control unit to minimize the impact of the renovation. Together they can create a hospital design than incorporates contaminant barrier and control techniques. Barrier precautions include:

• Separating construction areas from other areas with temporary partitions that prevent the spread of dust
• Closing off areas to foot traffic where renovations are taking place
• Isolating ducts that connect construction areas with patients
• Installing supplemental HEPA filtration units into the hospital air conditioning and filtration system

Hospital HVAC design must also account for the possibility of accidental disruptions to hospital services during the renovations and take measures to minimize that possibility. The hospital design team should be well versed in the existing building systems and make an evaluation as to what the impact of a renovation project may be. This should include a thorough inspection of the hospital and all it's systems including plants and rooms.

The hospital's facilities management team should be able to provide access to the building's systems. Relying on existing plans and blue prints is insufficient because they may not be accurate. The hospital HVAC design team should identify which areas in the new hospital design may be the most affected by the hospital air conditioning renovation and take the appropriate precautions.

A hospital air conditioning system is an essential part of its operation. Be sure to work with a qualified HVAC company that's well versed in the unique challenges related to a hospital air conditioning retrofit.

The Benefits of an Air Con Service Checkup


When it comes to a building, there are few things that are more important to the comfort of a building more than air conditioning. Keeping things cool when the weather turns warm is vital in any sort of structure, from a business or office building to a home. This is especially important in the warmer climates of the world. When you have a structure with air conditioning, it is essential to keep that unit running as smoothly as possible. If you ignore your building's air conditioning, it will cost you a great many headaches and a lot of money. That is why an air con maintenance plan is the best way to ensure that your air-conditioning system lasts as long as it possibly can.

It is likely that you may not understand much about an air conditioning system, most people do not know that much, in fact most folks only know about changing dirty filters related to their system. However, routine maintenance is much more than just replacing a filter. With an air con service agreement, you can have the many basics of a routine service check that will ensure that your system runs as efficiently as possible.

Changing a dirty filter in your air conditioning system is certainly an important aspect of regular maintenance that should not ever be overlooked or ignored, but there are many other steps that are just as important. Cleaning the evaporator coils as well as cleaning the drain pan is helpful in keeping things running well. In addition, with an air con service check, they will also check the air conditioners condenser unit, check all electrical components, flush the drain pipe, do a refrigerant level check and do a test run.

Air conditioning systems can give people a great deal of comfort when the weather turns warmer. This is especially important in those locations where the weather is warmer over long periods of the year. It is also important to understand that they can also cost a lot of money as well. You do not want to risk losing the comfort of cool air when the weather is hot and your air conditioning system simply because you ignored the regular maintenance of that air conditioning system. With regular maintenance performed by air con company, you can insure that with a little bit of attention, your comfort, not to mention your sizeable investment, does not go up in smoke well before its time.

What Is Was Like to Be Stationed on a Submarine Tender in the United States Navy


What is was like to have sea duty aboard a submarine tender.

The first thing I learned about being in the Navy, is that if your duty station is a ship, and it's moving across the ocean, sometimes it takes you, a long time, to catch up to it, to get on it. That was the deal with this ship, and the destroyer I was on also. It took me almost a month to catch up to the destroyer I was stationed on. It did not take me as long, to catch up to the ship. The ship was on its way to Subic Bay, in the Philippines. And I was going to meet it at the pier, when I got there finally.

After arriving in Manila, me and some other guys that were headed to the ship, stayed the night in Manila, for the first night. That was the first night I had spent in another country, ever, in my life. There were several of us, that flew into Manila that same day, and we needed to take a taxi about 2 hours south, to meet the ship.

We got a nice hotel room in Manila, it was overlooking the streets below, where all kinds of vendors, and jeep like taxis were everywhere, honking their horns non stop. We did not know what to do, so we stayed in the lounge of the hotel. That first night, we all drank right there in the lounge, and just stayed there. We had been traveling for awhile, and we were told not to go out and party, but we did party a little bit, but just in the hotel lounge.

The next morning, a white little van, with air conditioning, came and picked us all up. It drove us to the town where the ship was waiting. Along the way, you could see many different types of taxis, and tons of fields, that we all guessed, were rice fields.

The taxi drivers seemed to drive more crazy than in the United States. They swerved at stuff, hardly slowed down to let anyone cross the street, had tons of decorations glued all over the hoods, and it was all of them, that decorated their taxis heavily. They would honk their horns constantly, and sometimes if you are watching the driver, he is just honking the horn, to honk the horn. There were 3 wheeled motorcycle taxis that they called trikes, all over the place. They were the cheapest way to get around.

I consider myself to be a good motorcycle rider, since I grew up with dirt bikes and motorcycles all the time. One day, I asked one of the trike drivers, if I could drive his 3 wheeled taxi motorcycle. He said I would have a hard time, since I never did it before. I told him I rode motorcycles all my life, I can ride his thing. He bet me 50 pesos, which is about $1, that I could not ride it from one spot, to another. Boy, I drove it just a little bit, and I could not get it to turn around for me, so he was right, you have to practice riding on of those things, to figure it out.

I was the "fresh meat" guy, again, on the ship. This was finally going to be, the real Navy. A ship with over 1,300 people on it. Our office was almost at the very top of the ship. All the admin offices, legal, public affairs, recreation, the CO, XO, and Command Master Chief offices were connected together. The offices are connected together, so we can all use some of the same spaces. You had to do the standard duties anyone aboard a ship would have to do. Fire fighter training, drills, man overboard, abandon ship, nuclear spill, and other type of drills.

Everyone does special training, and you learn other things about the ship. One of my first duties besides being a yeoman, was you had to stand a watch, or serve on a flight crew, or salvage crew, or something like that. Even thou you are working in an office, at any moment, and even at 3:00 am, they might decide to do a drill, or the real thing.

One of my jobs as a seaman in the Navy, and working in the admin department, was during special sea procedures. We might be getting supplies from another ship, that is traveling threw the water, at say for example, 20 knots, and we are traveling threw the water, at the same speed also. We can transfer, fuel, supplies, food, mail, people, you name it.

They might use a helicopter to bring supplies over, from one ship to another, and during all this time, the Captain is up on the bridge, standing out on the wings, directing the ship at what speed it should be at, what course it should be on, and during all this time, he always has a young naval officer, at his side, since he is always training officers, at any given time.

The captain, who I must of saw train 50 different officers with the same thing, over and over again. Here we are, traveling at high speeds, two ships not more than 100 feet from each other. There will be a young ensign, or lieutenant junior grade, standing out on the bridge wings, trying to give the speed, and course, to the quartermaster and helmsman. Also, at the same time, he has the captain right behind him, putting a little pressure on him, telling him what to do, and asking him lots of test questions, and always testing them, and training them.

My job was to keep track of what speed and what course we were on at all times. The young officers would get confused, and could not remember what course, or what speed we were on. You usually just have to fine tune your course and speed, every so often, back and forth, just a little bit, but always back and forth, and the ships will be fine.

It looks really impressive, awesome, and powerful, to be out to sea, thousands of guys working, bright sunshine, crystal blue waters, and your cruising across the ocean, at pretty fast speeds, and you can see cargo, and other items being transferred from ship to ship, and you just think, wow, how cool looking is this.

One day, the captain was up on the bridge, and he was a pretty nice guy, he said, "Petty Officer Stead," even though I was still only a seaman at the time, he always like to call people by a bigger rank. He said, "You must of heard me say these things over, and over again, a thousand times by now, I bet you could drive this ship better than these officers."

I always knew when it was time to change course, I could of did what those officers were trying to learn, only because I was up there each time with the captain, when he was always training someone. It was never just the captain doing anything by himself, it was always either a drill, or an exercise, or a supply mission, he was always training junior officers, on everything he did.

One of my jobs was being the CO's phone talker during emergencies and drills. During battle scenarios, and other things we do, each department would have one person that was a phone talker, like the repair department, the medical department, the damage department, and all the other people connected.

The captain would bark out orders, and I would bark out orders to the other departments, it was kinda like I was barking out the orders, and it was kinda fun, because everyone took it so seriously, and from wherever the captain was at, there was always a good view.

On this ship, the captain had his own kitchen and cook. The cook was part of our department, as the Supply Department, and Executive Department, shared the same berthing space together. So we always shared our berthing with the cooks, and the supply guys.

The cook to the CO, was selected as sailor of the year, for the ship, and he was a good guy. His dream was to work at the white house, and he applied, but was rejected for the job. The captain had his own regular house size stove, refrigerator, and all the things one would have at home, in a kitchen. The cook, would ask the CO, what he would like to eat for each meal, and then make it for him. The skipper might reply, I want a light salad, steak, and whatever else he desired.

Everyone that is brand new to the ship, and is just starting out in the Navy, must perform 90 days duty, somewhere in the cooking section. Either as a cook, helper, cleaner, or whatever. My job ended up being in charge of about 3 frozen food lockers. Now on the ship, there must of been, at least 12 storage lockers, for milk, food, bread, hamburgers, you name it.

We had an elevator at each entrance, and at the top of the ship, we had our own crane. Before we would go out to sea, some semi tractor trailer trucks would come, and we would load the ship up with fresh food, and lots of it. On the ship, you usually get to have 4 meals a day, breakfast, lunch, dinner, and one at midnight again, called mid rats, for people that are still hungry, or people going on watch, or getting off watch. When you have 1,300 people it takes a lot of food.

Working in the food storage department for 90 days was fun, the guy in charge of us was pretty cool. We were always allowed to have the day off, as soon as you got your work done. That meant all of our work, so if someone was done, we would help the next guy get his work done, until all the things were done, and a lot of days, we were done working by noon, and we would be off for the rest of the day. Not too bad a job really.

Heat Pumps - Brands and Options for Efficient Operation


Simply put, heat pumps utilize the hot (geothermal) air outside and processes that air to provide warm or cool air (reverse process) through a ductless or ducted unit into your home. They are very energy efficient and give the homeowner comfort year round no matter the season. These units are a popular choice among homeowners today for their home heating and cooling from Tampa, FL to San Diego CA and even up into Canada.

Gibson - This company has been around the block and produces air conditioners and heat pumping units with split system setups, in 13 SEER fixed single stage, 15-16 SEER variable speed two stage and 14 SEER variable speed single stage systems.

Coleman - Coleman produces split system heat pumps that is an outdoor unit using electricity for the power source. It's highly energy efficient using the reverse cycle process for summer home cooling. Ductwork is required to carry the warm or cool air into various rooms throughout the home.

Daikin - These units are ductless, energy efficient, safe, compact, offer no excavation or digging installation and provide comfort year round as well as provide sanitary hot water for the home. These units are usually wall-mounted and require no ventilation or duct work.

Trane - Trane manufactures several models including their ultra efficiency XL20i and XL16i, super efficiency XL14i and XL15i, high efficiency XR13, XR14 and XR15 and standard efficiency XB13 and XB14 units. The ultra efficiency models include ComfortLinkII technology that allows for communication with indoor units (when present) and telephone capable setting changes when you set up the TAM feature.

Some brands of heat pumps use hydronic technology to grab the outside air which makes them even more efficient and usually quiet. Hydronics are considered a refrigeration process where the hydronic heat pumping system moves heat from a body of water or the earth into the home. Those using a body of water are referred as open-loop systems and those using the earth are referred as air source systems. These use a lot less electricity which also saves money for the homeowner.

If you think it might be time to upgrade your current heating and cooling system perhaps a heat pump would work for you. If you have problems with troubleshooting issues when converting from one kind of system to heat pumps a professional installer can help you and go through the process and cost that are involved so you can decide which brand will be best for you.

Central Air Conditioner Prices - Tune Up to Keep Costs Down


Obvious as it is, the expenses/costs that goes into buying a central air conditioner does not stop with the central air conditioner prices. Eventually, you'll also be spending on maintenance and some increases in your utility bills.

One way of keeping your air conditioning costs down is to have tune-up and maintenance performed regularly.

It's very important to have tune-up and maintenance done on your central air conditioning system once a year. Among the benefits that you can get from having them performed on your air conditioner regularly is the significant reduction in energy consumption (up to 20% or more).

Be careful, however. Not all tune-ups are the same. The real deal takes around an hour to an hour and a half to perform. If you've had one done in the past which took less than an hour to complete, it's quite certain that your service provided had ripped you off. Don't throw your money in those types of services because you're not getting anything good from it. None at all.

Another thing, even if you have a contract with the utility companies (no matter how cheap or expensive they are), keep in mind that utility companies do not perform tune-up and maintenance. That's because of the simple reason that doing so will bring your utility costs down. And they don't want that.

A proper central air conditioner tune-up has 24 points including inspection, lubrication, calibration, and cleaning. The entire system is completely checked, every aspect of the system and every component of the system is completely checked to make sure it that the air conditioning system is properly operated.

The entire system is also completely cleaned, including the outside unit. Cleaning the outside unit involves taking the lid off and removing all the dirt, debris, and any foreign objects/matters that have found their way inside.

The coil outside is also washed and cleaned during a tune-up. On the inside, the blower compartments is also completely cleaned and vacuumed during a proper tune-up. Just so that you know, having just 1/16 inch of dust accumulating on your central air conditioner's blower wheel can reduce your system's efficiency by 40% or more.

Then, also in the inside, there's also the cooling coil, the drain pan, the duct system, the condensate drain lines, etc. Each of these things/components should be thoroughly cleaned.

The bottom line here is this... if the air conditioning system is not thoroughly cleaned, it will deteriorate rapidly, drastically reducing its efficiency, as well as its lifespan.

So, get your air conditioning system tuned-up once a year and keep the operating costs down.
