SureFire Method to Resolving Failure For Lasting Success


Many years ago, one of the early founders to launch the "Air conditioning Industry" Mr Willis Carrier had a huge problem on his hands, as the equipment which he had just pioneered costing millions of dollars had not quite performed as anticipated, and already, some large volume of these had been commissioned.

This unexpected result was to cost the organisation a huge loss, and for him, a big blow to his reputation which till then was respectable in his ranking within the Senior Management.

Mr Carrier reckoned that this particular "Major Disaster and Blow to himself and to the Company" would see him being sent off a broken and disgraced man. He had sleepless nights, tossed and toiled in his confusion about this loss. Several times he asked himself how he was to own up, how he was to tell his family, how he could envisage going with such a mess left behind him. These worrying sensations continued, until all of a sudden, he decided to switch on his Thinking Cap.

Now, he thought to himself, what's the worse that can really happen? Ok, he'll lose his job in disgrace, and then he said, what's the next thing that could happen? He thought he would then have to pick himself up and go searching for a new job, perhaps slightly different from what he was doing then, but with the knowledge and experience behind him most employers he figured would want him.

After analysing all this, he picked himself up, wrote down all he had learned from his setback, and decided boldly to face his bosses with the hard truth, and other vital information he felt that would need to be applied to this problem in order to set things straight from the case of Losing Millions of dollars to that of Breaking Even and then Building up to Long Term Success.

Ok, what do you think happened when he bravely met up with his bosses?

He went through in detail explaining the facts and information that he had already researched. He presented them with alternatives and the reason for the massive setback plus how to correct it.

In this particular case, his bosses were convinced and accepted his proposals, agreeing to put them to the test. They had several more tests and eventually it was a success. Mr Carrier kept his job, kept his dignity and went on to create ongoing success for the organisation.

The blows of the initial trials had vanished because he reframed his initial setback, picking the learning's and moving on to review his options for success. If he had done the opposite, we'd be looking at an entirely different story now.

So, let's look at the term "Failure" in the light of the above example, because some people would view failure as something that didn't quite go according to their original or revised plan, hence they see it as a Failure.

In any case, whatever your circumstances or definition of failure, looking at it from an entirely different angle, the term "failure" could be reframed or put into a different context, which then transforms it to an entirely different meaning in such a way that you can see some benefits from the experiences gained. Sometimes benefits may not be immediately obvious as this may take a while to understand or appreciate.

This interpretation of reframing "failure" in the context of your new experience or learning's from an event, transforms the setback to an empowering resource, giving you options for change and improvement from the current position.

The reality here is that in any situation, when you're in a position to move on from the past setbacks, rather than having the mindset of "Failure", switch it to that of "Feedback" for growth. So you use the setback you've experienced as vital feedback for your ongoing growth and improvement in different areas of your life.

In the earlier example with Mr Carrier and the Installation that didn't quite go as planned, the vital results from the initial tests and setbacks were precious for the necessary improvement and Quality Control of the Product and to ensure that the organisation maintained Value to its customers.

Another example also is that of someone I know in the past who could never really settle to any job for longer than six months at a time, and so he went from one job to another, like a vicious circle. An incident in his life meant that he had to be off work for more than seven months, and it was within that time that he began to seek his real passion for work and lifestyle from deep within him.

He asked himself various questions in his quiet time, thought about what he really wanted to do including retracing experiences he had gained from his success ventures and setbacks he had learned from along the way. For him, it was then that he decided to put together his master plan for setting up a Training Organisation in the field that he really loved, and he has settled in this since.

So, in summary, the way we look at setbacks in our lives will also help to shape how we move on with different situations as we face Life's Challenges.

Now, in readiness to take charge and press on with life, review any setback with the anticipation of learning from that experience, at the same time, endeavour to carefully pick the learning's for you in particular, and let go of the negative emotions and feelings associated with the event or experience.

You'll find that once you truly let go, the release of the negative energy will actually set you free on your way to making changes in your desired direction. If you feel you need to engage a Professional Counsellor to do this, then do as your own Inner Mind directs you.

The Empowering Reality however in life is that "There are no Failures" only "Feedback". Always bear this in mind. If we decide to use the knowledge and experience gained in Life's Challenges as stepping stones for improvement, then we begin to realise the absolute release of Unlimited Creative Energy, lying dormant within us, and waiting to be given direction in which way to turn.

History of Air Conditioning


It is a wonderful thing to be able to flip a switch, and have an entire room cooled off through air conditioning. Portable room air conditioners make sense when you wish to cool certain parts of your home, office, or covered outdoor living spaces. Air conditioning is commonly found in buildings today, but it was not always the case throughout history.

Wealthy ancient Egyptian families could enjoy the cooling benefits brought from aqueduct water that traversed the insides of walls in buildings. Water was an expensive commodity in that hot region of the world, so only the rich could afford this luxury. Medieval Persians made use of wind towers and cisterns to cool their buildings. Wind would be captured in the wind tower, and it was then directed over the water in the open cistern, which would evaporate and cool the ambient temperature inside the dwelling.

Later on, the idea that liquefied ammonia, when it evaporated, could cool the air was thought up by British scientist Michael Faraday in 1820. In America in 1842, Dr. John Gorrie created a machine to make ice, and he used the ice to cool the air in his hospital in Florida.

Industry was the primary reason that air conditioners were created around the turn of the last century in the United States. Willis Haviland Carrier created the first electrical air conditioner in 1902, which was used to cool and dehumidify the air in a printing plant. The term "air conditioning" was coined by American Stuart W. Cramer in 1906, who came up with a way to add moisture to the air, which was crucial in his textile manufacturing mill.

Toxic gases were used to run the early air conditioners, but Thomas Midgley, Jr. created Freon refrigerant in 1928. Unfortunately, he did not know that Freon is bad for the ozone, and recently newer refrigerants have been developed that are safer for the environment.

Air conditioning is not only used today to make our homes and other buildings more comfortable. You will find air conditioning used in land, water and space vehicles. Air conditioning is used to also filter out bad particles in the air, such as in hospital operating rooms. If you have allergies or asthma, air conditioning can help remove the pollen, dander and dust that causes these conditions to flare up. The elderly can also be at risk if they are in a too-hot building, so air conditioning can be crucial for their well being. Some air conditioners are also dehumidifiers, which take the excess moisture out of the air to make you more comfortable in terms of your temperature. Today we are lucky that a great air conditioner is your answer for cooling comfort.

Mechanical Air Conditioners - Part II - Air Conditioner Parts


This article is an extension to "Mechanical Air Conditioners - Part I - Operating Principle", and I will be talking about AC parts used in mechanical air conditioners.

Air conditioner parts that we put into a mechanical AC, should conform to the operating principle. Air conditioning parts for this type of equipment are divided into three categories. The,

  • main and compulsory parts. This category is mandatory, otherwise, a mechanical air conditioner will not function at all

  • the support parts, to ensure that the air conditioning equipment last long, and function effectively, and,

  • the control parts, for improving efficiency of the equipment, and maintaining your comfort and bills - at optimum level

    Main air conditioner parts

    There are six parts in this category. Let's explore them one by one,



  • The compressor

    Used for compressing refrigerant into high pressure gas into the condenser, and pulling in low pressure gas from the evaporator. The high pressure and low pressure is created by the compressor.

    Common compressors used are piston type, scroll, and rotary compressors



  • Condenser and evaporator

    These are simple finned heat exchangers. These air conditioner parts, are formed using a serpentine shaped copper (or aluminium) tube, with aluminium fins.

    Although the functions are different, the operating principle of these parts is the same. To encourage heat exchange between the refrigerant and air.

    Condenser will function to liquefy high pressure refrigerant. Evaporator will function to completely boil low pressure refrigerant, into low pressure gas



  • Expansion device

    Common expansion devices are either capillary tube, OR thermostatic expansion valve. The function is to allow pressure build up from the compressor, and allow for refrigerant to expand into low pressure zone. This air conditioning part will also allow for boiling to start



  • Tube

    Tubes are air conditioner parts that has no moving parts. The main function is to direct refrigerant flow, and contain refrigerant within the AC. Common tube material is either copper, or aluminium



  • Refrigerant

    Air conditioners would not be able to cool, or heat anything without a refrigerant. Therefore, this part is essential. Refrigerant is used for absorbing (at evaporator), and expelling (at condenser) heat.

    Common refrigerant type used in mechanical ACs are the HCFC (hydro-chloro-fluoro-carbon), and HFC (hydro-fluoro-carbon)



  • Fans and blowers

    Fans are placed at the condenser, and blowers are placed at the evaporator - to aid heat exchange. Blowers will also provide better air circulation within your house - and these supply with cool air to you, from the evaporator

    Support air conditioning parts

    These are conditioner parts provide the protection to the main parts, such that those will last long, and operate reliably. The list,



  • Filter dryer receiver

    Functions to filter small particles from the compressor, remove moisture within the refrigerant, and in some cases, acts as a receiver to supply full liquid column (without bubbles) to the expansion valve.

    It is placed before the expansion valve, and after the compressor



  • Filters

    What more can I say. Air conditioner filters will prevent dust, and other particles from clogging up the evaporator. Of course, you'll have to clean or replace it periodically



  • Tube insulation

    Is the simplest air conditioning part and utilised in refrigerant return line. This part will prevent icing, and condensation on the refrigerant return line.

    Essentially, it will keep the refrigerant from evaporator cold, and allow for better cooling of compressor. Additionally, you'll save on utility bills



  • Muffler

    As the sound deadening air conditioner part, placed at the outlet line of the compressor



  • Casing

    Well, to make sure you can transport main sections (condensing unit and evaporating unit) in simple packages, and used to protect sensitive and main air conditioner parts

    Control AC parts

    These air conditioner parts are more like the "essential accessories" for any mechanical air conditioner. Here we go,



  • Thermostat and humidistat

    The former AC part is used for controlling the temperature, and the latter for controlling the humidity. Thermostat is used in ALL ACs, but not humidistat. However, the inclusion of humidistat into the system in conjunction with thermostat is common in central ACs



  • Contactor

    Is and electrical component used to control the switching on, and off of compressors, fans, and blowers.



  • Dampers

    Dampers are used in central ACs, to control flow of air, such that you'll get the right comfort from the air conditioning equipment. Dampers is almost vital in central ACs, as it is difficult to balance heat gain and loss requirement in each room - from a single condensing-evaporating central unit

    By now, you should have a general idea of what are the air conditioner parts that make up a complete mechanical air conditioner.

  • A Tribute to the Car Air Conditioner


    If you are living in regions characterized by long summers like I am, you probably would understand what compelled me to pay a tribute to my Car Air-Conditioner. I cannot imagine driving everyday to the office in this hot and humid weather without my trusted Car AC. I am sure there are millions of people out there who would agree with me when I say that a Car Air-Conditioner is not an accessory, it is a necessity. In hot climates, an air conditioner can make your drive a pleasurable experience even if you are not driving a luxury car.

    It is imperative that you are comfortable while driving and any concerns in this regard can be distracting. With an AC you can be assured that you won't be complaining about the weather. This will definitely allow you to concentrate on your driving and enjoy it too.

    Let's discuss how a Car AC works and what can we do for its maintenance.

    A Car Air-Conditioner is responsible for the cooling and dehumidification of a closed car cabin. It functions on a simple process to draw heat from inside the cabin to the outside.

    It does so by deriving power from the car engine to run its main constituents i.e. the Compressor, the Condenser and the Evaporator. In fact, it is the Compressor that is connected to the car engine and acts as a pump that circulates refrigerants in the AC system.

    Refrigerant gas flows in a closed circuit from the Condenser (located outside the cabin) to the Evaporator (located inside the cabin). The pressure produced by the Compressor drives the refrigerant gas throughout the system. For this reason, the Compressor is called the heart of the Air Conditioning system.

    The pattern flows like this; the refrigerant gas is compressed by the Compressor and passed on to the Condenser. The gas is condensed here to cool it and increase its density. The cooled refrigerant passes to the Receiver Dryer (a part in the system that gets rid of any moisture formation in the gas). The cold refrigerant then passes to the Evaporator.

    The refrigerant flows through the narrow tubing design of the Evaporator Coil at a temperature of 0degree Celsius. A fan located behind the cold Evaporator Coil blows cool air into the cabin through the air vents in the dashboard to provide immediate cooling. There is also the process of dehumidification that happens when warm air inside the cabin comes in contact with the cold surface of the Evaporator. All impurities and dust particles in the cabin-air stick to the Evaporator and get passed out along with the moisture formation on the Evaporator surface.

    The refrigerant that gets heated in this process passes back to the Condenser and gets cooled again. This continuous cycle provides the cooling effect inside your car whenever you switch on your car air conditioner.

    Although running an AC means increased fuel consumption because it is powered by the car engine but believe me, sometimes it is just worth it. I always advise people to make judicious use of their car AC to avoid crying for fuel efficiency later.

    A Climate Control system or Automatic Cooling in your car means that the AC is always in operation to keep the temperature inside your car at a constant level. If you can afford it, then you should let your car air conditioner do it but if you want to save fuel as well, here is something you can do.

    * Maintain the speed of your Car AC at lower levels while driving and increase the level when the vehicle is stationary (e.g. at traffic signals). This will increase fuel efficiency while keeping your car cabin cool.

    * Use a heat rejecting film (whether transparent or tinted) on your car windows. This will help to keep the cabin cool for longer periods of time reducing frequent use of the AC.

    * Service your car air conditioner every six months to maintain it at peak performance. This will increase the efficiency of your car AC and in process save a lot of fuel too.

    When it comes to the maintenance of your Car AC, follow these basic steps to get the best use of it:

    * Check the refrigerant level in the Air Conditioning system to avoid extra load on the engine. Replace the refrigerant if needed.

    * Check the compressor drive belt (that connects the Compressor to the Engine [out] ) for signs of damage and monitor any changes in tension of the belt. The belt may get dried-up at times but you can put a drop of oil on the belt occasionally to keep it moist.

    * Check all hoses and connecting pipes for hardening, bubbles, cracks and leaks. Repair minor damages as soon as possible to avoid major ones.

    Apart from these checks, you can maintain the coolant pressure in the AC by running it for 10 minutes every month at its highest speed and coolest setting. This will also prevent the hoses from hardening and cracking while getting rid of any blockades, dust, micro-organisms and mildew. While you do this, make sure all the car windows are open and no one is sitting inside the car.

    With some basic care, you can enjoy the benefits of your Car Air Conditioner for a long time and not spend anything on its maintenance or repair.

    The Facts & Benefits of Buying a Heat Pump


    Reduced Heating Costs

    Significant savings can be achieved by installing a Heat Pump system. A small amount of primary energy is used to create over three to four times the same amount of Heat Energy to be used within the property. For existing users of Gas, savings of up-to 17.5%, LPG users 59% and for Oil users a massive 61% can potentially be achieved.
    Cost Chart for Fuel Types

    Indicative fuel cost comparison per 10kWH

    * Gas - 34p
    * Oil - 60p
    * LPG - 58p
    * Air Source Heat Pumps - 33p
    * Ground Source Heat Pumps - 27.5p

    N.B. For this cost illustration, a price of 11p per kWH unit of electricity has been used which is representative of current prices (July 2008). The indicative fuel and utility costs used in this example may not be representative of actual costs and tariffs available due to fluctuations in fuel costs. It is advised to assess any potential savings against your actual utility costs and tariff and your projected yearly heat pump running hours and heat load.
    Complete Climate Control

    Heat pumps are an all in one Heating & Cooling system which are able to provide high grade Hot Water and Heating to Residential or Commercial properties and with the added benefit of optional Air Conditioning.

    Increase business opportunity

    Heat pumps are a great opportunity for existing plumbing and installers to expand their service portfolios and product ranges with a water pipe work based heating and cooling application.
    A Flexible Solution

    A water based system and significantly reduced refrigerant volume means the Air or Ground to Water Heat Pump is able to provide a cost effective and efficient option or existing split VRF/VRV applications.

    Straightforward Installation

    The Heat Pump system gives a plumbing / water pipe work based air-conditioning & heating installation that provides on demand simultaneous Heating / Air Conditioning and Domestic Hot Water.

    Increase Property Value

    As a recognised cost and carbon saving energy solution, simply installing a Heat Pump system to a residential or commercial building can potentially add significant value to a home or business property

    Reasons to Hire a Heating and Air Professional for Your Installation Needs


    If you need a new heater or AC, it is important to hire a professional. It can be tempting to try to do it yourself to save money, but in the end, you will likely find that it is not worth the hassle. This is why you should consider the reasons to hire a company for installation of heating and air conditioning equipment.

    First, you need to make sure your current system is not repairable. In most cases, repairs are cheaper than buying new equipment, even if you try to install it yourself to save on labor costs. Most heating and air companies will take a look at the current unit and try to fix it. If it is apparent you need a replacement, then it is time to think about the additional benefits of hiring someone for the job.

    You might not know where to begin when it comes to getting the unit that is best for your house. The good news is that most companies that can install systems can also help you choose the right one for your house. This will be based on the size of the home, the number of floors, and how often the unit would be used. In addition, certain preferences you may have, such as energy efficiency, will be taken into consideration when professionals present you with your options. Having the company do this for you will be less time-consuming than you doing the research on your own.

    Of course, having the installation performed by a company can definitely save you time. What might take you all day or even all week would likely take a team of professionals a few hours. Your time would be better spent working, raising your family, or even simply relaxing. This is why hiring a business for your heating and air needs is often recommended if you do not have the training required for this job.

    In addition, there is always the fact that you might not be able to install the new equipment correctly. The result is that you could damage your house or the new unit, wasting money. You might get it all installed only to find it does not work correctly, requiring you to hire someone after all if you want a working heater or AC.

    Clearly, there are some good reasons to pay a professional to do this task. In fact, the same reasons are valid when it comes to repairs. Therefore, you should start looking for a business with reasonable rates rather than trying to save money by doing the job yourself.

    Hydronic Radiant Floor Heating - How Does it Work?


    So, you're sold on the idea of radiant floor heating. Of course the question becomes "What type of system do I get?" Radiant floor heating comes in three varieties: electric, hydronic (liquid), and air based systems. The hydronic system is the most popular, for reasons that will be revealed shortly.

    The "how" of hydronic radiant floor heating is fairly straightforward. A boiler heats up water, which is pumped through your house. This water flows through a network of tubing that sits just underneath your floor, radiating the heat outwards, giving you a nice, consistent heat that is the trademark of the radiant floor heating systems.

    This method makes for quite an efficient system. In fact, hydronic systems are the most popular radiant floor heating systems on the marker. Since liquid holds and stores heat quite efficiently, hydronic systems uses less energy than almost any other heating system. However, since you'll need a boiler, a plumbing system, and installation underneath the floor, they aren't easy to install. In fact, they are quite a pain unless you're building a new house or an addition, in which case they can be a great option.

    Keep in mind that you're not going to be getting any cooling from this system. If you need cooling, you'll need to look for alternate methods, such as forced air, or evaporative coolers. These can coexists peacefully with in floor heating, so don't worry. Just something to consider.

    There are two types of hydronic systems available. The traditional "wet" system embeds the tubing into a concrete slab on the floor, which makes it quite efficient, since the concrete slab will absorbs heat and continually radiate it outwards throughout the day.

    A "dry" system puts the tubes underneath the floor framing. A series of reflectors and diffusers help contain and diffuse the heat evenly. These systems are great if you don't have or don't want to deal with a concrete slab, but they aren't quite as efficient. They are still a good option, though, if your situation demands it.

    If you are building or renovating your house, and you want to try a new, luxurious heating system, be sure to look into radiant floor heating. Because of it many advantages, you just might find that it becomes your favorite thing about your house. Talk to a professional today to learn about this great heating system. Thanks for reading.

    Top Interferences to Central Air Conditioning


    The summer heat can be a strain on even the strongest air conditioning unit. Because of this, many homeowners frequently complain that their air conditioning does not keep their home as comfortable as they would like. There are many different things that can cause your HVAC system to work at a lower efficiency than it should, making the problem sometimes difficult to diagnose. Start with some of the following tedious yet important tasks before installing something new.

    Leaking Air Ducts

    One of the main causes of poor heating and air conditioning system performance is leaky air ducts. Your ducts are very similar to your plumbing pipes, except that they deliver air throughout your home. We can see damage to plumbing immediately, because water leaks everywhere. Air ducts, on the other hand, sneak up on us because the leaking is not readily apparent. Whenever our ducts leak, they are effectively wasting cooled air into the attic or other space that they are in. In order to prevent this, your ducts should be sealed at all metal-to-metal and metal-to-flex connections. To do this, your insulation should be pulled back and the joints sealed with mastic. Duct tape just doesn't quite do the job.

    Too Little Or Too Much Refrigerant

    Another common cause of poor AC performance is your refrigerant charge. Most central air systems use a refrigerant that helps to transfer heat between the inside and outside. Your particular system will work best with a certain amount of refrigerant, meaning that it will function at less than capacity with both more or less refrigerant. This can lead to up to 20-30% of a decrease in efficiency.

    Incorrect Air Filter Installed

    Always install the proper air filter. While most HVAC systems were designed to use cheap, fiberglass air filters to filter the air coming into the system, they are not always the best choice for the job. To remedy this, many people go out and buy a high-efficiency air filter that is much better at keeping the air in their home cleaner. The problem with this, is that these filters sometimes decrease the air flow. This can reduce the efficiency of the entire system. Choose a filter that both filters out unwanted particles and allows sufficient airflow.

    Insufficient Return Ducting

    Return ducts are absolutely necessary for the proper functioning of your HVAC system. Many systems, however, have only a single return somewhere in the middle of their house. Each room is supplied with its own source of conditioned air, but it all has to find its way back to this central location to be cooled once again. Whenever doors are closed, the space between the floor and the door is not always sufficient to allow the air to return back to the return vent. This leads to some rooms being hot and some being cold. One solution is to have a heating and air contractor install additional returns to assist in evening out your cooling system.

    Is the Do It Yourselfer Putting Air Conditioning Repair Co Out of Business?


    Air conditioning contractors across the western states report record low earnings at the close of summer 2012. Though it is still too early to say for sure but some companies speculate that their earnings will be down more than 20% by yearend.

    Jeff Delgado a 13 year AC contractor that employs 9 technicians, down from 19 last year, said that he sees 3 causes for the decrease. The number of foreclosure is pretty high right now so those systems don't get repaired. With the economy so tight we are seeing more and more people that will pay us to diagnose the unit then will repair the air conditioner problem themselves. The last reason is there are a lot more parts houses today that sell direct to homeowners. In the past this was next to impossible to find. Any part that you need to fix your own air conditioner can be bought online. That makes it very hard for some contractors to stay competitive.

    Jeff's reasoning seems to hold true to most areas throughout the US. Homeowners seem to be searching for ways to save a few bucks and learning to repair your own air conditioner or heater is on that list.

    A central air conditioner is made up of 22 basic components that have a specific job when cooling or heating your home. 18 of those AC components can be replaced using the kind of tools you would find in a common toolbox. The remaining components involve the refrigerant lines and a closed gas system. Fortunately these are the least likely parts to break on an air conditioner. For this reason it seems that Do It Yourself types are flocking to the internet to read and watch videos on how to repair your own air conditioner and heating.

    Some online air conditioning parts stores also offer help with deciding what you need to make the repair. They might also make suggestions on what to do for preventative maintenance. The key to dealing with them is terminology. So if you do not understand what they are talking about ask for a description.

    Like any electric appliance, there are a number of precautions to take as you fix your own air conditioner.To spite the fact this is an electrical devise with 230 volts, it can be remarkably safe to fix if you just follow a few simple steps. The most important is to cut the power, and then discharge the capacitor. Follow these steps to ensure your safety when you repair your own air conditioner and furnace.

    Air Conditioning Repair For Refrigerant Leaks


    One of the most commonly sought after air conditioning repair needs is due to a leak of refrigerant. This can happen to older systems more commonly than new, though it can happen to any system. The problem is, this is the type of repair best left to the professionals. It will likely require several steps to get the repair underway. However many individuals find that getting these repairs is far easier when they turn to a technician who can handle the repairs quickly.

    What Is It?

    In this type of air conditioning repair, the system runs low on refrigerant. This product within the system circulates and keeps the cool air coming. In some cases, the initial device installed into the system was undercharged. This means that not enough of the product was in place at the time of installation. In other cases, though, it can leak.

    In situations where the leak does occur, simply refilling the product does not solve the problem. Rather, the professional will need to inspect the system, determine where the leak is, determine the best steps for repairing it and get the system back up and running. In short, the leak must be found and repaired before any additional refrigerant is added to it. Otherwise, the leak will simply continue to happen.

    In order to keep your system running at its optimum level, especially for energy efficiency, the refrigerant level needs to be full or at the recommended levels from the manufacturer. If it is overcharged, the problem is just as troublesome as if it was undercharged. This is why it is essential to allow a professional to handle this process.

    Keep in mind the refrigerant leaks can be worrisome to the environment as well. Because this product is not safe for everyone to touch, allow a technician to inspect the system and to determine if there is a leak.

    Common Signs of Leaks

    Individuals who are unsure if they have a refrigerant leak need only to look at the way their system is running. The system likely runs well, which indicates it is not the motor. If it turns on and off, this indicates it is not usually the thermostat. The underlying problem, then, may be the refrigerant.

    To find out for sure, call a technician for air conditioning repair. The technician will be able to tell you right away if this is the problem. Refilling the unit is not expensive, but it is essential to repair the leak, too. The cost of this type of service will ultimately depend on the scope of the problem. However, most professionals can offer a clear quote for the service if you request it before getting started.

    Do You Have an Air Conditioning Maintenance Schedule Yet?


    If you have air conditioning, no matter whether in a small shop or department store, hotel, or office block, you'll really appreciate it, and know what benefits it brings when the weather, is hot or cold. It's important then, that you look after it, by having an air conditioning maintenance schedule.

    Here's why.

    1. You air con needs servicing, just like your car, or other appliances do. You wouldn't expect your car to work as well if it hadn't been serviced for years, so why should your air con?

    2. Different sorts of heating and ventilation systems will have different maintenance requirements, so just because you might have known the schedule of a previous air con, or the system where you used to work, doesn't mean that this one will be the same.

    3. Your business will depend on being open, and ready to trade, and no matter whether you're a small newsagent, or a large hotel chain, you don't want it to suddenly fail, and have all the associated problems. Can you afford to lose customers because your store is too hot or cold? Will workers be able to function properly if the office block is too hot or too cold?

    4. By having an air conditioning maintenance schedule, any repairs that are needed, can be carried out at your convenience. You might want to have the work done out of hours, or at a weekend, or whenever you'll be least inconvenienced.

    5. You'll want to choose a well known air conditioning firm with a good reputation to carry out the service, and any work that might need doing. If you don't know who installed your system, you might want to see who other people use.

    6. Have a heating and ventilation system that works properly, will be more efficient and effective, and so it will be better for all concerned. You'll know that it is optimised to give the performance your workers or customers need,

    7. Once your air con is working properly, you'll have the peace of mind that it's unlikely to suddenly fail on you, at a busy, or business critical time.

    8. You'll also be reassured that prevention rather than cure is the best way forward. If you have any worries about your air conditioning, or want to know what the funny noises or strange lights are, then you'll want to get the system checked out as quickly as possible. With an air maintenance schedule, you'll be able to call an engineer out, without having to pay premium call out charges.

    9. You'll want to ensure that your air conditioning saves you both time and money, so having it regularly checked, and well maintained, can pay dividends in the long run. Paying for a maintenance contract now, might save thousands in lost trade.

    10. Most importantly, an air conditioning system that works properly, helps to provide a better atmosphere for staff and customers. Your staff will work more efficiently and effectively when they are at the right temperature; browsers are more likely to become customers if they're not too hot or too cold; hotel guests are unlikely to enjoy their stay if the temperature of their room isn't right.

    Now you know why it's so important, you'll want to arrange an air conditioning maintenance schedule as soon as possible, if you haven't got one yet.

    Air Conditioning - How to Keep Your Electricity Bills Low


    Are you finding it harder to budget for the amount of money you pay to your electric utility? This is a very common problem since most people have to deal with the rising cost of living on a fixed salary. At the same time, it is very hard to expect oneself and one's family to do without the comfort of an air conditioning unit because weather conditions have made summers too hot to handle and winters far colder than before. Thankfully, there are ways in which you can manage your air conditioner so that your electricity bills do not climb too high.

    One of the first things you should do is pay close attention to the weather and set your air conditioning according. The amount of cooling you require during the peak of summer is undoubtedly high but you certainly do not need to cool your house to the same level when the weather cools. In fact, you might not even require air conditioning during some of the days late in the year.

    Make sure that the air conditioner you use is placed correctly. Most people recommend placing it on the north side of the house so that it does not have to work too hard to cool the house. You should also use the right sized air conditioning unit for your room or house. A small unit will have to work too hard without giving satisfactory results whereas a very large one will use up a lot of energy.

    You have to take care of your air conditioner well so that it works efficiently. This involves cleaning its filter as well as condenser and coils. You can do it on your own if you check the owner's manual. It is also a good idea to get it serviced twice a year.

    Most people who have central air conditioning do not realize that they can save quite a bit of money by closing the air vents in rooms that are not occupied. You might have to take a bit of trouble to monitor this but it is certainly worth the effort. Another thing that you could do on really hot days is to close the intake of air from outside so that your air conditioning unit circulates air inside the house. If you do not do this your machine will pulls in hot air which it then has to cool, thereby using too much energy.

    If you have a large window that bears the brunt of the sun's rays then you should close it with a blind so that the heat does not enter the house and reduce the cooling effect of your air conditioner. Another thing that you should always do is have the slats of the blinds pointing towards the ceiling and not downwards so that the sun's rays cannot warm the room.

    These cooling tips will help you get the most out of your air conditioning system without having to pay too much money in electricity bills.

    Does Your American Standard Air Conditioning Unit Need Some Basic Cleaning and Maintenance?


    An air conditioner requires basic yearly care to perform well and with the right maintenance an American Standard Air conditioning unit will continue to be economical and have a long life. Basic knowledge such as changing air filters and keeping the area around the unit clean is known by most homeowners. Doing these small maintenance chores makes a big difference in how well your unit runs. Air units that do not get cleaned and maintained on a regular basis lose an average of five percent of their efficiency for every year that passes.

    A well maintained system can cut costs by as much as a quarter of the bill. The problem with many homeowners is that they are unaware of everything that needs to be done to keep their units running competently. As long as it is cooling and the filters have been changed, they are considered to be kept up. Below are some tips that can help you determine when and what needs to be done to your American Standard air conditioning unit for continued productivity and operation.

    Caring for Your American Standard HVAC Unit

    There are multiple things you can do to ensure your American Standard HVAC unit is performing at its best. Changing or cleaning the filters when needed can make a big difference. The unit being used in your home can get dirty over use. Clean filters catch most of this dust accumulation. Another thing you can do to help is blow out and clean the unit itself each spring before operation. Ducts need to be free of blockage. Your American Standard HVAC unit should not have leaves, sticks and other debris surrounding or lying on top of the unit casing. This reduces air flow and increases how hard the unit must work to cool your home. Other items need to be cleaned and checked yearly. This includes major components like the compressor, coils, and fins. Do not use a hose to clean these parts. Other more superior cleaning methods are safer. If you are unsure of what needs to be done, contact a professional.

    When Does a Commercial HVAC Professional Need to Care For Your Unit?

    It is recommended that each year you hire a commercial HVAC professional to clean and maintain your American Standard unit. Professional servicing is better than attempting to do all the maintenance and cleaning yourself. The internal parts of a cooling system are fragile and require special care. Replacing them is very expensive and the wrong cleaning method can actually bring on costly repairs. Having a commercial HVAC professional clean and check your unit each year can prevent large repairs and keep it running soundly.

    When a major part breaks such as the compressor, it could take weeks to repair and be very expensive. Consistent maintenance will bypass these occurrences most of the time. All major components are checked, repaired, and cleaned with a yearly service call and the chances of your unit breaking are greatly reduced. If repairs need to be done, they are much cheaper when noticed early. The cost of a simple service call is well worth the benefits it can provide.

    Steps to Take in Air Condition Gas Leak Problem


    An air-condition gas leaking problem is extremely difficult and costly to solve.

    An initial step to identify gas leak is by checking the gas pressure level with a pressure meter. If the pressure meter shows zero, that is the sign of gas leak because the compressor can never be emptied.

    The air-condition technician will then pump in the freon, either R22 to 68PSI or R410a to 135PSI to the air-conditioner, this depend on what refrigerant your air-conditioner takes in. You can check what refrigerant your air-conditioner takes in by looking at the label beside the fan coil unit.

    From there, the technician will monitor the gas level. If the pressure drops within a few days, weeks or even months, this is a confirmation sign of gas leak because if the gas is top-up fully, it will last at least for a year. The rate of leaking is also dependent on the size of the crack.

    So where is the leak source usually from?

    The leak can be at the fan coil, inside the condenser or the copper pipes. The cracks are usually found at the joint soldering portion and copper pipes near the compressor. The crack occurs when two copper pipes touch each other and due to the vibration of the running compressor, the copper pipes will crack and gas leak occurs.

    There are few methods and equipment used for identify leak source.

    1. Hand-Held Refrigerant Leak Detector which detects a leak. A beep sound will be heard when it touches the copper pipe.

    2. Ultraviolet (UV) Dye which detects a leak by inserting a coloured dye into the copper pipe and the colour will show where the leak is.

    3. Soap and Water. Bubbles will form when the soap and water is placed on the leak site.

    Once the leak is found, here are the methods to seal of leaks:

    1. Compression Tape is used. The tape will seal the leak source when the tape is placed over the leak area.

    2. Soldering. Soldering is a process in which two or more metal items are joined together by melting and filling the leak area with a filler metal.

    In the methods and equipment mention above, fixing the leak may sound simple. But in fact, gas leaks are extremely hard to detect and seal. Especially if the leak source is in the copper pipes, it is almost impossible to detect the leak as it is concealed inside the wall, and it is very hard to perform soldering to seal up the leak source.

    10 Simple Air Duct Maintenance Tips For Your Home


    Keeping your air ducts clean can provide you with cleaner air inside your home. Irrespective of whether you have have a professional do it or if you do it yourself, some simple air duct maintenance steps can help cut down on the contamination of your air vents. Air duct maintenance revolves around 2 aspects, reducing the volume of foreign particles (rodent droppings, insects, insect droppings, pollen) which makes its way into your air vents, heating and cooling system and preventing moisture from getting into the air ducts.

    Tips to reduce the volume of dust and debris in your heating and cooling system:

    1. Utilize the highest efficiency air filter you can afford as recommended by the manufacturer of your HVAC system.

    2. Replace your air filter regularly. How frequently is dependent on where you live, whether you have a pet, if anybody smokes in the home and how how often your system is used.

    3. Be certain every filter is in place (a lot of heating and cooling systems use multiple filters) and they fit properly to prevent air from getting around the filters.

    4. Anytime you have your heating and cooling system serviced, have the technician clean the coils and drain pans.

    5. Do not operating your HVAC system and block the return and supply vents throughout any significant home renovations that generate a large amount of dust.

    6. Dust and vacuum your house regularly. If at all possible use a high efficiency (HEPA) vacuum along with the highest efficiency filter within you're budget.

    Moisture in your air ducts is never a good thing. It can cause mold, bacteria and fungi growth which may cause health problems. Moisture in air ducts believe it or not is not entirely rare and can be caused by HVAC system or by other elements leaky pipes or leaks in your roof. Research shows that condensation on or near cooling coils of air conditioners is a major contributor of moisture in air ducts. Condensation is normal and is produced when the temperature of air in the heating and cooling system is below the dew point temperature of surrounding air. Newer system, when operating properly, have features to remove this condensation without contaminating the duct work. Improperly installed heating and cooling systems, incorrectly serviced systems and malfunctioning systems can lead to damage related to condensation.

    Steps to prevent your system from getting wet:

    1. Repair all water leaks and water damage immediately and completely

    2. Cooling coils, when operating properly, remove water from the air and drain pans remove the moisture from the system. Both coils and drain pain should be inspected on a regular basis. Drain pans should drain completely so standing water in the drain pan implies the pan is not functioning correctly. The drain pan should be free of debris which could possibly impact its ability to drain properly.

    3. Airducts should be sealed and insulated when they are in areas which are not cooled such as attics, crawl spaces or garages. This helps reduce condensation by decreasing the temperature variation between the air within the ducts and the air directly next to the air duct.

    4. If your are replacing your air conditioner be sure the new air conditioner is matched to your size home. An air conditioner which is over sized will likely cycle on and off more frequently which reduces its ability to remove moisture from the air.

    The Best Insurance for Your HVAC System - Regular Service


    Regular maintenance and inspections are an important part of owning any kind of commercial building. The problem for many owners is that they wait until something goes wrong to have their HVAC system serviced. However, it is important that you be proactive about your system.

    In fact, you could consider regular maintenance service as the best insurance policy you can have against a serious system failure. Keeping the system up and running will save you money because it will increase the system's efficiency. Did you know that about 40 percent of your electric bill is from your HVAC system? By taking steps to make sure it is running as efficiently as possible, you could see a significant savings in your heating and cooling bill.

    It is certainly very easy to keep putting off regular maintenance because it feels like you don't have enough money. But what do you do when something serious goes wrong? You certainly won't have the money then either. By preventing serious problems with just a little bit of money now, you are likely to prevent the need for expensive fixes and longer down times later on. In addition, you will extend the life of your heating and cooling system by making sure that regular maintenance service is performed on it.

    Creating a Maintenance Schedule

    One of the best things you can possibly do for your commercial HVAC system is to create a maintenance schedule. This will help keep you on track for making sure that these standard maintenance tasks get completed. Contract with a reputable company for regular service at various times of the year so that these important service calls do not fall through the cracks. By having a maintenance plan in place, you can count on the company you hire to call you and remind you that service on your HVAC system is due.

    Here are some tips to help you create a maintenance schedule you can live with:

    • Make sure all filters in your system are changed about once a month. Put this on your maintenance schedule and include it in with the duties of your technician. This way you won't forget to change the filters.

    • Schedule regular checkups at least two times per year. The best times are during the fall and the spring. These are periods of change for the temperatures, so you will want to make sure your heating and cooling system is entirely ready to go.

    • When the company you have hired to follow your maintenance schedule calls, don't wait to schedule that appointment. It is too easy to let these service things go rather than to stay on top of them. You will likely divert major disasters later.

    There is nothing worse than an HVAC system malfunctioning, so you should do everything you can to prevent that. Employing a maintenance schedule and actually following it is like creating your own insurance policy for your HVAC system. You help ensure that potential problems are caught early and avoid major disasters.

    Troubleshooting Gas Furnace Problems


    Are you having a gas furnace problem this time of the year? It could be very difficult, not to mention expensive to have one repaired or replaced. But before you panic and spend thousands of dollars for repair or replacement bills, check first what's wrong with your equipment. If you find out, maybe you can still salvage it from being replaced and yourself from spending on unnecessary feels.

    One of the most common furnace problems is that it doesn't release heat to your home. Sometimes even though it's turned out, you will still feel that you are getting colder by the minute. Don't panic just yet. Common causes of this is low gas pressure or a low voltage. Turning the power on and off and will reset the unit, and if the cause is as simple as the ones mentioned, it will be able to function normally again after you have switched it on and off a few times.

    Another common problem that happens is the gas furnace emitting varying degrees of heat. It may still not be as serious as you think. Common causes of this is a dirty filter and a clogged blower. Making sure to keep those two clean will eliminate this problem immediately and prevent worse ones from happening for years. So if you think you are not cleaning your furnace enough, you better start now unless you want to spend more than just on cleaning materials.

    One of the most hazardous furnace problems is carbon monoxide emission, which happens even when it's working properly. To avoid any potential danger, you need to have a carbon monoxide detector to prompt you when the carbon monoxide levels have already reached a dangerous level.

    Air Conditioning - Behind the Scenes


    When the temperature warms up in the house, you head over to the thermostat and lower the setting. This triggers the air conditioning system to kick in and pump the nice, cool air into your home. All you had to do was push a button or flip a switch, but there was a lot of behind the scenes work going on for that cool air to blow in.

    Whenever the thermostat signals your air conditioner to lower the temperature, a sequence of events takes place. The air handling unit begins drawing air in from various parts of the house through return air ducts. This air is pulled through a filter where airborne particles are removed. Then the air is then cooled and re-routed to duct-work which carries it back into the house. This cycle continues every time the air conditioner is running. Now that have the big picture of how an air conditioner works, let's break it down a little further.

    An air conditioner has three main parts - a condenser, a compressor and an evaporator. The compressor and condenser are usually located in the outdoor unit. A refrigerant or cooling agent such a Freon circulates between copper tubing that runs between the components.

    The refrigerant receives and releases heat raising and lowering in temperature. When it does this it changes from liquid to gas and then back to liquid again. When it first begins to circulate through the indoor coil, it is extremely cold. As the air is pushed across the coil, the refrigerant absorbs the heat. When enough heat is absorbed, the refrigerant then turns to vapor. The vapor then travels to the compressor and is pressurized and moves to the outdoor coil. There the heat is forced out. A fan helps to dissipate the heat. Then the refrigerant passes through a device that converts it to a low temperature liquid and is then returned to the indoor coil. Then the cycle starts all over again.

    As you can see, your air conditioner goes through a lot to keep you cool and comfortable. So, make sure you do your part in helping to keep the unit running smoothly with yearly maintenance with a reputable heating and air company. And remember the next time you turn down that thermostat to be thankful for all the behind the scenes work that goes on to keep you cool and comfortable.

    Air Conditioner System Benefits - Room Air Conditioning Systems


    If you have difficulty in sleeping at night because of the heat, why not install an air conditioner in your home. Having one can provide a more comfortable sleep.

    Air conditioning is a way of cooling a room in the form of a refrigeration cycle. It was first invented by Stuart Cramer but actually the term was coined after Willis carrier. It is available in various sizes and also with various cooling capacities and prices.

    Air conditioning systems reduces the humidity of the air and it maintains the quality of the air. There are also some that would dry the air without cooling it. It is usually composed of a condenser, evaporator and a compressor component in it.

    It also uses a chemical that could convert the liquid to gas and vice versa. Most air conditioning systems also uses the split system and a package system. In the split system, the condenser and compressor are placed outside the room and the evaporator is placed inside the room.

    The evaporator is used in circulating the air throughout the room. In the package system, all components are placed outside the room.

    An air conditioner can give you comfort through the day and it can help you in many ways. For instance when the air cooler was invented and first installed in the Houston theatre, a vast difference is seen. The number people who visited the theatre gradually increased after the installation.

    In hot climatic weather as in summer, no one could concentrate on the work or can satisfy their work. So the scientific invention helps people in many ways. Air conditioner also makes a vast difference in the transportation.

    There are also industry grade air conditioners used in many manufacturing sectors for various purposes.

    Air conditioner from the time of its invention has been a beneficial one till now. It has been almost used in all commercial residential and industrial sectors. Most of the commercial sectors use centralized air conditioner which performs same as the regular one.

    The advantage of using the centralized air conditioning is that it produces less noise in indoor as the unit is placed outside the room.

    Your Heating and Air Conditioning Has Unused Capacity


    In today's rough economy and with utility costs rising, everyone wants to save money. Most people are paying more than they should for utility costs every month because their heating/air conditioning system isn't be used to its capacity. Your heating and air conditioning system includes the ductwork and filter.

    Most people think if they have 97% efficient furnace and newer air conditioning system that they are doing everything they can to save money on heating & cooling their home. In most homes because of poor duct design the systems are operating at less than 60% of rated capacity. Most of the time when a high efficient air conditioning system is installed with a poorly designed duct system the efficiency gets worse. This happens because the high efficient air conditioning coils are larger and restrict air flow more than a smaller coil.

    Studies preformed by National Comfort Institute and the Department of Energy have found that most homes with forced air heating & cooling systems have 40% or better of unused capacity.

    This is not hard to understand if you think about this. If you have a forced air heating & cooling system you are paying to condition air.

    Unused capacity is the amount of air your heating & cooling is capable of conditioning but can't because it is not there to condition. Every minute that your burners are on in your furnace or air conditioning compressor is running any unused capacity is just wasted energy.

    One way to think about this: You have a tub you have to hand fill with water.

    You want to fill the tub with 50 gallons of water: You have a 1 gallon bucket. but instead of filling the bucket with a gallon water and dumping 50 times. You fill with 翻 gallon of water and dump it 100 times.Your capacity was 1 gallon but you only used 翻 gallon of the bucket which took more energy to fill the tub.

    A forced air comfort system (Furnace and/or Air Conditioning System) is doing the same thing if it is not have the proper amount of air through the system. Remember you are paying to conditioning air. That is what you want it to do.

    Very few people and this includes most of Heating, Cooling professionals don't look at it as a system.

    They look at it as a Box (Furnace or Outside Condensing Unit for Air Conditioning. (This is not knocking any contractors; unfortunately this is what we are taught. Most of the training in the Heating & Cooling Industry comes from Furnace and Air Conditioning Manufacturers and their job is to sell equipment not maintain existing equipment or repair inadequate ductwork.)

    When a furnace and air conditioning system is installed and airflow is not addressed your odds of winning the lottery are better than the actual results of that new Super High Efficient Equipment delivering what you were told it was going to do

    You may save some money but to really save money the equipment needs to run less and the best way for this to happen is for it to be sized properly, (Most equipment is oversized) we still believe bigger is better. Your equipment should be as small as possible. Meeting a properly preformed load calculation for your home or business and then it needs to be used to capacity. Sorry this is getting off topic.

    In all of that few things I would like you come away with are:


    1. You do not have just a furnace and/or air conditioner you have a Comfort System.

    2. Your Comfort System's Job is to condition air. (All Year Long)

    3. If you have never had an airflow analysis it would be a wise investment. You may find that some duct renovation would be a very good investment.

    Wall Placement of a Window Air Conditioner


    What one sees of a window air conditioner from the outside is the sleeve, a metal box with ventilation louvers that houses the actual air conditioner. One sees a similar box for a wall air conditioner. Naturally, people assume they are the same. But they aren't, and this article will explain why.

    The two types share some characteristics. Both span the dividing line from inside to outside, allowing all components to be housed in a single box. Therefore both utilize both inside and outside air to perform. Both are designed to condition a single room. But there are differences.

    Windows are thin, and the sleeve for a window unit is designed to take advantage of this. It sits on the window sill, with the window closed onto the case to seal the top. Side panels fill the gaps on the sides. These are also very thin, so most of the sleeve is uncovered and outside. This allows for placement of ventilation louvers on the sides and top, allowing free movement of air.

    This is the primary difference between the two types. The wide availability of louver space allows the unit to move a lot of air, and this means window units can be quite powerful, up to 3 tons, or 36,000 BTU! So window A/Cs can be effective for very large rooms.

    In contrast, a wall air conditioner sleeve is designed for a hole through the wall. Walls vary substantially in thickness. A wall with simple sheet type siding may be only 6 inches thick, whereas a brick or stone wall can be much thicker. So wall air conditioner sleeves have ventilation louvers only in the back, to avoid louvers being covered by the wall edges. This limits the amount of ventilation space available, in turn limiting how powerful the unit can be. Wall air conditioners generally don't get much over 14,000 BTU, depending on the brand.

    So are they interchangeable? This question usually arises when someone needs a lot of cooling power in a room without suitable windows for a window unit. The answer is, It depends on the wall thickness. Sleeve specifications for some window air conditioner manufacturers include the maximum wall thickness before it will cover part of the louvers.

    For example, Amana's 18,000 BTU models have a max of 8.5 inches. If the wall thickness is at or below that, these models can be used in as a wall air conditioner without adversely affecting function.

    So what's the problem if the wall covers a little of the louvers? Two things: 1) restriction of air movement and therefore reduced efficiency, and 2) these units pull air in very powerfully. Cut wall edges could become loose, allowing material to be sucked into the unit and potentially causing damage.

    At least one manufacturer, Friedrich, has a line of models with sleeve options. For the same model, one can get a different sleeve designed for the intended use.

    Making Your Air Conditioner Last Longer


    Air conditioners are not cheap. You definitely do not want to be buying a new one every year or so. A bit of preventive work can make them last.

    One of the biggest problems with most air conditioning units made today is that they are tough, and well built. This may not seem like much of a problem, but what happens is that most home owners become very complacent about their air conditioners. They continue to run and run year after year, and many people tend to worry little about them as long as the air is cool and comfortable. The truth is that without routine maintenance, a normal air conditioning unit loses about 5% of its efficiency each year. This means that within a short time your powerful SEER 13 unit is working more like an older SEER 8.

    A good air conditioner can last 15 years, or even longer, with just routine maintenance. It will also operate at its rated capacity for most of that period. Much of the maintenance that is required to keep your unit up to snuff is inexpensive and easy to perform. The first step is to make routine inspections of your unit to discover any potential problems. The best time to perform any air conditioner maintenance is a little bit before it is needed. Check all hoses for leaks and make sure the condensate tube is draining freely.

    Filters are critical to the proper and economical operation of the air conditioning unit. They should be inspected often and changed or cleaned monthly. This is even more important during the summer months when there is a higher level of dust and pollutants in the air, and, of course, the units are running more frequently. Other methods of insuring maximum air flow through the system include cleaning and vacuuming of the registers and air vents. You should also insure that furniture and drapes are not blocking registers.

    The outside compressor should be cleaned with a hose. Plantings should be kept at least a foot away, and grass and weeds should be trimmed to insure adequate air flow around the unit. Remove any debris from the fan area. During the winter months, the compressor should be covered. It is also a good idea to remove any window air conditioners during the winter, and store them until they are again needed. A yearly tune up of your air conditioner by a certified technician can cost between $50 and $100, but can result in as much as a 5% reduction in yearly operating cost.

    You can also increase the life of your air conditioner by finding ways to not have to use it. Programmable thermostats can regulate temperature to decrease use at night or when the house is vacant. Simple things like ceiling fans or attic ventilation fans can reduce the demand on the air conditioner. Even planting trees to increase shade or using drapes over windows facing the sun can help. Reduction of use combined with proper maintenance can increase the life span of any air conditioner. One important safety consideration is to make sure that all power is turned off to the air conditioner before performing any maintenance.

    The Refrigeration Cycle


    Refrigeration works by mechanically circulating refrigerant through a evaporation and condensation cycle. Low temperatures and pressures encourage evaporation, while condensation occurs in areas if high temperature and pressure. One side of the loop is inside an area of low temperature like a refrigerator, and one side is on the outside air. This two sided design of the loop allows the transfer of heat.

    As a basic overview of the mechanics, as the low pressure liquid refrigerant expands at the evaporator inlet, it absorbs heat and evaporates into a low pressure gas. The compressor then pumps the gas through an accumulator which builds pressure for discharge into the condenser.

    The accumulator protects the compressor from trying to pump solid or liquid freon. All Denver HVAC systems should come with an accumulator to protect air conditioning compressor life. Compressors are the most commonly ordered part by Denver air conditioning companies. Compressors are especially susceptible to varying load conditions and frequent compressor on/off cycling.

    Condensers remove heat from the gas until it condenses back into a high pressure liquid. Some optional parts common in a Denver air conditioner are drain valves, heat exchangers, and liquid line valves.

    The expansion device is between the condenser and evaporator. A liquid line strainer should be installed before this part to prevent problems from the buildup of dirt or moisture. The pressure between these valves is maintained by thermal expansion. As the refrigerant liquid is sucked into the evaporator, its pressure drops and the liquid absorbs heat as it expands and evaporates.

    Once the desired interior temperature is reached, the thermostat sends a signal to the central air conditioning or refrigeration unit to shut down. The system turns back on when rising heat in the evaporator enlivens the circuit.

    Test Driving a Motorhome


    New Motorhome

    Make an appointment with your chosen dealer in advance. Few dealers will be able to make a specific test vehicle available at short notice. It is best to allow plenty of time to cover every detail, so ask the sales person about planning a route and make any other specific requests, such as loading and additional passengers. If you're test driving a demonstrator model, check whether it has the same engine and specification as the model you want to buy.

    Used Motorhome

    If it's an older motorhome you want to try, ask if you can start it yourself. If the engine is warm when you arrive, it may have been pre-warmed to disguise any starting difficulties. If the clutch bites at the top of the pedal's travel, it's probably worn, so ask about a replacement. If the steering pulls to one side, the tracking needs to be adjusted. If there's a lot of play in the steering wheel, the steering gear may be worn and that is fairly serious.

    Test Drive

    Test drive using the maximum number of passengers you are likely to be carrying on a normal trip. Check if their feet can touch the floor. Is there enough room for a child booster seat? Will the heater or air-conditioning be up to the job in extreme conditions? If possible, simulate a full load - if it's a garage model, ask the sales person if you can load your bikes or scooter to see how the motorhome copes with the weight distribution. If you like to drive with a full water tank, ask to fill it. Ideally, visit a weighbridge to check the motorhome's weight, either unladen or, better still, with your kit in it. (Remember, many weighbridges need to be booked in advance.)

    Plan your route to sample all possible driving conditions and make it long enough so that you can get a genuine feel for the comfort levels of the travel seats. Include a steep hill, a section of motorway or dual carriageway and some urban driving. Try a hill start, to see how the clutch feels. Consider long-trip factors: for example, will the stereo provide enough volume for all passengers to easily listen to audio books or music on long journeys?

    Overnight Parking

    Does the motorhome fit in your driveway? If the dealer is local and your drive is difficult to get into, it's worth checking to see how easily you can park. Consider whether it will be more difficult to negotiate at night and assess the security of where you intend to park. Check how easy it would be to empty the waste outlet on a campsite with no dedicated service point. Can you fit an extension to empty the waste water into an ordinary drain?

    Driving

    Try parking the motorhome as you would on tour - if you prefer smaller motorhomes and like to park in town centres, see how this works. If it's an older motorhome, will anyone else likely to drive the motorhome be able to cope without power steering? If you sometimes drive alone, try parking on your own. If the motorhome is an A-class (which may have only one cab door), or an import with an offside habitation door, where will each passenger get out?

    Accessories

    Do any retro-fitted accessories, such as reversing sensors, work as they should? Consider which accessories you need to fit and how these might affect visibility. An obvious one is a rear cycle carrier, which lengthens the vehicle and restricts your rearward view.

    Usability

    Cover all the angles. Simulate any difficult visibility conditions you may face, particularly if driving abroad, such as driving on the right-hand side of the road and turning left down a hill, with poor visibility of oncoming traffic. Can your passenger see enough to tell you when it's safe to pull out and will rear passengers obscure the view?

    Noise Test

    Complete a noise test. Drive the motorhome over an uneven road surface to see whether its squeaks and rattles or sets your teeth on edge. But, before you set out, make sure you've done everything sensible to stop noise, such as removing grill pans and baking trays from the cooker. Check the cupboard locks before you drive away, and that everything else is secure.

    Maintenance and Repair

    Identify the best service agent for the base vehicle in terms of quality of service, size of workshop (availability of short-term servicing) and cost. Ideally, this will be the supplying dealer or one of their sub-contractors. Consider spare parts costs and servicing cost over the vehicle's life span.

    Finally

    These are just a few steps to get you in the right frame of mind when viewing a motorhome for the first time. Motorhomes are big and so you should spend a lot more time examining one than you would for buying a car. If something doesn't feel right, ask the owner or dealer and make sure you are happy with the reply before moving on. If there are any doubts it is far better to walk away giving yourself time to reconsider, rather than buying the motorhome and having the rest of your life to reconsider.

    How to Identify the Best Central Air Conditioning Systems


    To identify the best central air conditioning systems, you have to do more than rely on the word of the seller. A heating and cooling company is like any other company: it's in business to make money and will present you with the best case scenario for all of its products, even when some of those products represent a "good" choice and not the very best choice for your situation. In general, the best central air conditioning systems are those that operate on minimal electricity to keep your electric bills as low, offer dependable performance for their projected lifespan when properly maintained, operate quietly and require minimal servicing throughout their life span. To evaluate particular air conditioning systems by these criteria, researching professional and customer reviews is an excellent resource. But before you decide to buy an air-conditioner, you'll need to answer two questions concerning your particular needs and wants.

    What Unit is the Right Size?

    While an air conditioner that's too small won't be able to keep your home as cool as it should be, buying an air conditioner that's too large will turn on and off more frequently without providing a higher level of cooling. In addition to amounting to wasted money in term of equipment cost, a system that's too large can also saddle you with significantly higher electric bills, as well as decrease the lifespan of the air conditioner due to the extra strain that results form its turning on and off so frequently. To determine the right size air-conditioner for your home, it's best to have an HVAC technician conduct a thorough study of your cooling requirements, which will depend on such factors as window dimensions and exposure, square footage, your house's landscape orientation, the presence of direct shade, local climate and insulation. When the technician finishes his investigation, he'll identify what size air-conditioner you need in terms of Btu/h or tons. Btu/h stands for British thermal units of heat removed per hour and one ton is equal to 12,000 Btu/h.

    Is Energy efficiency an Option?

    Air conditioner manufacturers are required by law to rate their air conditioning equipment in terms of energy efficiency, which is known as a Seasonal Energy Efficiency Rating (SEER). The higher an air conditioner's SEER rating the greater its energy efficiency. In most cases, new homes are built according to a standard builder's model. But when it comes time to replace your air conditioner, moving to a more energy efficient model is always a plus. Energy efficiency air conditioning is an option for every home, and while air conditioners with the highest SEER ratings can cost more than lower rated air conditioners upfront, they typically more than make up for your initial investment by offering you significantly reduced electric bills over the course of their lifespan.

    The Benefits of Outsourcing Facilities Management Services


    There are a number of benefits to outsourcing your facilities management services. First, let's look at the types of services that are available.

    These include:

    Retail park maintenance - retail parks will be fully maintained and you will receive photographic evidence of the work carried out


    • Pest control - professionals will prevent and eliminate pests such as rodents, insects and birds

    • Electrical services - trained specialists will deal with all your installation and repair needs

    • Paving services - full pavement design and implementation services are available.

    • Tarmac and white lining services - tarmac patching is available, as well as normal tarmac. White lines can be applied from a wide range of stencils, all to traffic regulation standards. You will not have to deal with local authorities or necessary permits - it will all be handled for you

    • Fencing and security services - security fencing can be implemented to fit with your business needs

    • Air conditioning - all your air conditioning needs can be managed, including installation, servicing and maintenance of air conditioning units

    The advantages of outsourced facilities management

    Facilities management tasks are often complex and specialised. That's why choosing a specialist provider will free you up to do what you do best - running your business.

    Flexible services - Using a service provider, rather than employing permanent staff, gives you the flexibility to bring in staff as and when you need them, in the numbers that you need them in. There's also the added bonus that you don't have the hassles related to interviewing, training and laying off workers to cope with fluctuating demand.

    Efficiency - Facilities management firms are specialists in their field and carry out these tasks day in, day out. They also have access to the latest equipment and products. This means that they are likely to be able to work much more quickly and efficiently than in-house staff balancing the jobs with other unrelated projects.

    Cost savings - Of course, quite understandably, the bottom line is what's important to most businesses. Using an FM company means that you pay a flat fee for the services. This makes it simpler for you to plan your budget and manage costs.

    You don't have costs associated with administration, wages, holiday pay, bonuses and more.

    Customer service - Outsourcing your FM needs to experts means the jobs will get done to a high standard. It will leave you and your employees free to focus on your core business so customer services should be boosted and your reputation will be maintained.

    What Are Your Central Air Conditioning Options?


    There are many options available for those looking for central air conditioning. Many manufacturers are making new central air units with more capabilities such as producing balanced temperatures and being economically efficient. Here are the top five central air systems and units (including products that are considered a home dehumidifier):

    3 Ton Haier Complete Split System Central Air A/C System- This system unit comes with an AC package which is fully equipped with an AC Condenser and air handler. Included in this package is an AC coil and 10 KW heat strip. Cooling temperatures are set on high as it is powered with a R-22 refrigerant. The total condensing unit weighs over 3 tons and has a BTU of 34,000. Other features include a framed bristol compressor along with a fan motor (which is lubricated). Consumers will notice the galvanized construction. The construction is protected with a metal jacket. This system can also produce warm temperatures as it has an enhanced 'heat transfer'.

    SPT WA-9000E Portable Air Conditioner With Remote- According to many central air conditioner ratings, this portable unit has received many good reviews amongst consumers. The product dimensions are; 26.5 X 35X 18 inches and it weighs an estimated 176 pounds. The portable unit provides cool and fresh air at the same time. The unit has a 75 point dehumidifier attached. Other features include a 3-speed fan. Consumers can control temperatures with the digital thermostat control feature. The LCD display allows for easy viewing and better control over temperatures.

    Comfort- Aire BHD-501-G Dehumidifier-This dehumidifier comes with a low-temperature feature which can be set below 41 degree F. Consumers can control humidity levels with the built-in humidistat. It also comes with a set of digital controls and an air filter. In case of the event of a power failure, the unit will restart on its own. The unit also has a control panel to reduce the over*saturation of moisture in small or medium size spaces. Some other features includes 'overflow shut-off'.

    DeLonghi PAC A120E 12,000-BTU Eco-Friendly Air Conditioner- The manufacturers of this unit made sure that it was 'economy friendly'. The system comes with a control panel which allows consumers to set up programmed times. The LCD display makes it easy to view temperature settings. It has over 4 fan speed settings and electronic controls. To save energy, a sleep and smart mode was created along with a built in air filter, which is good for mold and mildew removal. An exhaust hose and window bracket is also included.

    Adding Central Air Conditioning to Your Home


    In many parts of the country, air conditioning is an absolute must-have item. Not only does it create a comfortable oasis from frequent summer heat waves, but lacking any form of AC can also severely damage the resale value of your home. Considered only a few decades ago to be a luxury item reserved for high end homes, air conditioning is now almost universally seen as a basic appliance, as common and expected as central heating in even the most modest households.

    Advantages of Central Air

    While many homes still make do with window air conditioners, central air has many advantages. Most importantly, a window unit can usually only cool a single room at a time. In a pinch, several small rooms can be marginally cooled together, although this is extremely inefficient and requires the use of additional fans to blow cool air from one room into the other. A central air conditioner will cool every room in the house and provide a comfortable, uniform temperature throughout. Also, a whole house air conditioning system uses only one compressor motor and one circulating fan, which provides a huge energy savings over several individual window air conditioners running simultaneously. Although the motor on a central air unit is much larger than a window air conditioner, it operates on 220 volts, which uses less current to produce the same amount of cooling as its window counterpart.

    Additionally, a central air conditioner provides quiet cooling to the entire house. The compressor is placed outside the home, usually in an unused corner of the yard, allowing it to hum away all day unnoticed by the occupants indoors. This creates a much more comfortable indoor environment when compared to the loud din created by window units, even when the compressor itself is cycled off. Finally, the power drain created by several window air conditioners running simultaneously can overtax the electrical systems of older homes. Any given electrical circuit can only accommodate a single air conditioner before blowing a fuse or tripping a breaker, and many older homes were built with only two or three circuits to power the entire house. Modern construction codes now require a separate circuit for every five or six wall outlets, but even then, the simple act of running a sweeper while your window AC is running can send you to the basement to reset a tripped breaker.

    Disadvantages of Central Air

    Aside from the initial cost, there are no disadvantages to installing central air in your home, but there are a few conditions in which central air will be more problematic. Houses with boiler heat do not have the necessary duct work to run central air. Likewise, homes with electric baseboard heating will also require extensive modification in order to enjoy the quiet comfort of a whole house air conditioner. While it is possible to run relatively thin pipes throughout the building to deliver the cold air, it is a significant additional investment. If your house is not suitable to affordably add central air, there are several multi-room outdoor air conditioning units on the market that run delivery tubes outside the home and can deliver cold air to up to three rooms per unit.

    Whichever path you choose, the addition of central air conditioning will add greatly to your summertime comfort level and increase the value of your home.

    The Overheating Window Or Central Air Conditioning Unit - How Much Heat is Too Much?


    Is your Central Air Conditioner Condenser or Window Air Conditioner overheating? Maybe they are and there is a problem or maybe not. The First thing to remember is that the main purpose of the air conditioning unit is to remove heat from the space they are cooling. This means that heat will be coming from the discharge of the unit. How much is normal and how do you tell what is normal?

    Heat is a normal by-product of cooling. The process of cooling any space will require that the refrigerant is cooled and the excess heat discharged to the outdoors. In the case of central air conditioning this is done through the condenser fan and is usually discharged straight up. If the condenser coil is hot and the fan is not running then there is a good chance that the fan motor has gone bad. Check for power to the wires going to the motor. If there is power going to the motor (110V) then the motor probably needs to be replaced. The most common problem with the condenser fan motors is the failure of the bearings in the motor. This will cause the fan to turn hard and then it will not run.

    If the condenser fan motor is running and there seems to be very little air coming out of the fan, then the coil may be plugged with dirt. I have written an article on cleaning the condenser coil for information on how to fix that problem. A dirty condenser coil will kill the efficiency of the unit and also make the compressor work much harder which will kill that more quickly also.

    On window air conditioners the coil can also over heat. If the fan fails on them you will not have any discharge air on the inside either. This is because the same motor through a double shaft runs both the inside fan and the condenser fan. Most of the time the problem with overheating on window air conditioners, is because of a dirty outside coil.

    This outside coil can be cleaned, but the air conditioner should be removed from the window to do it. You also have to be careful when you clean window units so you do not get anything wet that will fail because of water. If you can pull the unit out of the outside chassis, do that before trying to clean it. Make sure that it is totally dry before reinstalling it and applying power to the unit.

    As you can see the most common cause of overheating with any air conditioning unit is a lack of maintenance to the unit. Always make sure to keep you air conditioning unit cleaned thoroughly for the best performance. Make regular cleanings a practice that you do faithfully every year. In very dirty places you may have to clean the unit more often than that. Lastly remember that heat will be given off of the unit when it is running. Do not confuse that heat with a problem heat. When an air conditioner is running it will seem to be very hot in some places. This discharge of heat is normal operation of the unit.
