Air Conditioning Unit - Which One to Choose?


Air conditioning has come a long way. During summer you need air conditioning to stay at home. To drive to office you need it in the car. In office too you have it. In short, you have air conditioning everywhere. You cannot live without it nowadays. There are different kinds of air conditioning systems; namely central air conditioners, window and split type air conditioners.

Central air conditioning is used in big enclosures like supermarkets airports and high rise buildings where cooled air is supplied from a central location. These are huge units using water cooling with cooling towers which are maintained and operated under the supervision of engineers. For houses and small offices it is the small unit which is suitable to cool a small room. In small air conditioners there are two types; namely split type and the window type.

Window type is good for a small room but despite using new technology they are very noisy. The only advantage of the window type is that when it breaks down the replacement is very easy. In contrast the split type makes very little noise. As a result most houses use this type for small rooms as it is more efficient and less noisy. In the split type, compressor is located outside the house and the evaporating unit inside the room that needs cooling. The compressed liquid of coolant gas brought into the house through copper tubing is evaporated in the evaporator. This arrangement makes it less noisy as half the unit is placed away from the room.As it is more efficient and emits less noise the best option for households is the split type.

These days manufacturers of air conditioners use CFC free gas to help preserve ozone layer. So, next time you replace your old window type air conditioners buy split units. Air conditioning is of such importance that you must give it priority in selecting them

Why Did My Air Conditioner Break Down?


If your air conditioner has stopped working the two most likely culprits are usually a single defective part or lack of routine maintenance. Similar to your car, your air conditioner is a mechanical system and requires regular maintenance and service. How long would you expect your car to last if you never changed the oil? How long could it go if you never rotated the tires or checked the brakes? The same thing can be said about one of the most important pieces of equipment in your life, your air conditioner. Without a routine maintenance program, our automobiles break down and so do our air conditioners.

Unfortunately, most of us get complacent when it comes to conditioning our living space. We do not want to think about air unless there is something wrong with it. We fall into the classic trap of out of site, out of mind. We may not even notice that our energy bills are climbing higher and higher every year. That is when the "hot summer" hits us the most. The utility bill doubles and we end up writing multiple large checks.

If your air conditioning system is over 10 years old, excessive energy consumption and frequent repairs are the trademarks of worn out system. Although many systems can function for many more years, a new high-efficiency system can save you time, money, and headaches. They may even pay for themselves by dramatically lowering your utility costs.

If your air conditioning system is under 10 years old a routine maintenance service is almost always the preferred choice. Many homeowners don't know that they can significantly increase their air conditioning performance with annual or biennial check ups.

The most expensive option is the "if it ain't broke don't fix it" sentiment. Chances are that an old air conditioning system will fail when it's working the hardest and you need it most. Contractors know this and adjust their prices accordingly. Not only are you waiting one to two weeks for an "emergency" install, prices increase 15-20% during peak months. The pressure on your wallet may be the least of your concerns. A damaged or defective air conditioning system can put you and your family at risk from a fire, biological, asbestos or other hazard.

Take a few moments and think about your air conditioning system. If it's over 10 years old it's probably time to start budgeting for a new high efficiency model. If it's less than 10 years old, make sure your system is professionally maintained so you can keep your cool and your utility bills low.

Choosing Between American Standard Air Conditioning Systems


While deciding which air conditioning system you are going to buy, many factors should be taken into consideration. As air conditioning systems get older they become less reliable and energy efficient. It is generally a good idea to invest in newer and more energy efficient American Standard air conditioning systems instead of keeping older models of air conditioning systems. Air-conditioning units come in several different varieties. There are portable units, central air units, window units, and through the wall units. At the present time, the majority of modern buildings in the United States are built with central air ducts throughout them. These AC systems require professional planning and installation in any building. Central air ducts are difficult to retrofit into older buildings unequipped with air ducts because of how large and bulky they are. Because of the difficulty of adding a central air-conditioning system into an older building, they most often make use of alternative air conditioning systems.

By comparing several types of American Standard air-conditioning systems, you'll quickly notice that each unit has a different collection of features. Determine which air-conditioner features are most important to you, and which would be the most likely to be utilized on a day to day basis. A few features you can choose from among different air conditioners are: adjustable thermostats, fan speeds, cooling speeds, and energy efficiency. You should always look for a unit with features such as exhaust vents, moving or adjustable vents, and an easily accessed air-conditioning filter. In addition to these mostly standardized features, some units also contain specially designed electrostatic filters which help alleviate allergy symptoms for homeowners by removing extremely tiny particles from the air introduced to a home. While comparing features, you should also take note of each manufacturer's warranty, and the length of the full replacement guarantee time line.

One of the most important features for American Standard air conditioning systems is their energy efficiency ratio, often abbreviated as an EER. An energy efficiency ratio measures how energy efficient any air conditioner unit may be. Higher energy efficiency ratios mean the air conditioners are much more energy efficient. This feature is particularly popular since energy efficient air conditioning units cost less money to run each year, and contribute less pollution to the atmosphere. Energy efficient air conditioning systems are unfortunately slightly more expensive than their inefficient counterparts, but the initial investment is almost always recovered over the lifetime of the AC unit. By the end of the life of the unit, you will have actually saved a considerable amount of money by investing in an energy efficient unit. EER ratings range anywhere from around 11 for smaller units, with large and more efficient units ranging around the 13 EER mark. Of course, the most basic necessity of an air conditioner is to cool down and condition air. An appropriate calculation for how many BTUs you require for the space you need can help you save money as well. Over cooling or under cooling a building is never efficient.

Heat Pump Tips - How To Prolong Your Heat Pump's Life


Heat pumps are a wonderful invention. They are very convenient and eco-friendly, and are very effective in temperature control and the fact that they are efficient energy savers is just a bonus to why it's a recommended investment for any home. But although heat pumps help users save money in the long run, they are quite an expensive purchase so it's very important that they are used and taken care of properly and carefully so that they would last up to its maximum life span.

The most practical advice that could be given to owners is to use the heat pump wisely. This would help the user save more money in terms of electricity consumption because he or she would use it only in times really necessary. Having the pump powered on for an entire day, or having it on the highest temperature level would mean that the pump has to work harder therefore increasing electricity consumption and might cause it to wear out faster and make it lose its efficiency as well.

It is also advisable to have a professional install the heat pump properly and have a programmable thermostat installed as well so that users can easily adjust the temperature of the unit and adjust it according to the temperature desired.

It's also important that users make sure that they clean or change the filters at least once a month. The filters are the only part of the heat pump that owners can easily access so it's the easiest to clean. It traps dust particles that clogs the coils and could lead to an increase in the energy consumption of the heat pump as it works.

Owners should also read the manual and check for the manufacturer's instructions on the requirements for how often this should be done on their unit. Another important thing to do is to make sure that there is nothing that obstructs the airflow for indoor and outdoor units. Reduced airflow can decrease system performance and can even lead to compressor damage if it goes on for a long period of time.

For indoor units, owners must make sure that no units are blocked while for outdoor units make sure there is no grass or shrubs or any plants that would block the air flow.

A number of factors could lead to poor performance of a heat pump such as incorrect settings or incorrect motor speeds, as well as loose fan belts. To avoid this, owners can check the fan speed, and clean the coils and fans as well. The fan motor needs to be lubricated regularly too.

For outdoor units, owners must regularly check for ice and snow that could build up around and on top of the unit that could cause blockage in the air flow. Do these regular maintenance checks on unit so that more serious problems can be avoided. It is also recommended that a yearly check up by a professional be done on the heat pump to ensure that it's at its tip top condition.

Heat pumps are predicted to last for an average of up to about 15 years, and to ensure that users are able to maximize their units and have it last for a long time; they must do their parts to take care of it and by following the tips mentioned here, they can do just that.

Air Conditioning For Computer Rooms - How to Keep Them Cool


We all know that chilly feeling we get when we enter our office or server room. This is not because our bosses are cranking up the coolness factor in order to freeze us into completing our work at a rapid pace. Computer room air conditioning is the reason. Computer rooms need to be below a certain temperature in order to function at full capacity as well as to avoid servers out. Here are some reasons as to why computer rooms need air conditioning.

It is essential that all server rooms contain some form of air conditioning. Computers are highly sensitive to environmental factors and too much heat may affect a computers functions. Computer rooms heat up owing to the electrical power used in the area. Their vulnerability to heat can result in them shutting down involuntarily as well as damaging data. The right amount cool air in certain areas of the computer room can help to avoid any computer catastrophes. Computers perform operations that we cannot live without, so it is imperative that servers are kept cool.

There should be a low level of humidity in computer rooms as well as some air movement. It is key that your computer's hardware is comfortable and that the room is at a required temperature of 20-25°C in order to avoid over-heating. The humidity range of any computer room should be at a cooling of 40-55% with a maximum dew point of 17°C.

A certain amount of outside air should be let into the room but only in small portions. This is why all server rooms should have doors that are always closed. The cooling of a computer room can be done by making use of portable air conditioning hire or having an air conditioner installed. Air conditioners can cool the return space air below the dew point and avoid any amount of condensation on the computers themselves. An air conditioning unit or various units can be used to avoid temperature changes in the room.

An air conditioner's main function is to keep the immediate area around it cool and comfortable, and this is highly important in areas where information is being processed and stored. Contact an air conditioning specialist for your computer room needs in order gain advice and knowledge about what type of air conditioning system you should use.

HVAC Service Specialists Encourage Use of Ceiling Fans


In addition to taking advantage of the best HVAC service can offer when upgrading from inefficient appliances to more eco friendly and cost effective models, you can also use ceiling-fans to help cool your home. Air conditioning services can help keep your appliances working smoothly and as energy efficiently as possible. But in addition to energy efficient HVAC service professionals, ceiling fans should also be used to keep costs as low as possible during the hot summer months.

Before air conditioning services became popular, ceiling fans were the most commonly utilized method to cool homes and businesses. Warm air was pushed downward during the winter, and hot air was given cool breezes during the summer months. Over the course of a century, many different kinds of ceiling fans have been put to use. Different settings have been implemented, materials used, finishes given to the products, overall aesthetic styles changed, and accessories have been offered along side the fans. Air conditioning services are now standard in all modern homes and commercial buildings, but ceiling fans are still used because of how affordable they are to run.

The popularity of ceiling fans has continued over the years due to how practical they are. They can dramatically decrease the cost of daily air conditioning services, while only costing a few cents each day to run. While used in conjunction with an HVAC or standard air conditioner, the thermostat can be lowered by several degrees while still maintaining a high level of comfort for everyone in the building. Setting your thermostat higher by just a few degrees can have an enormous impact on the overall cost of your air conditioning services. During the cold winter months, ceiling fans can help circulate warm air throughout the building instead of allowing warm air to collect only at the highest points of the structure. Trapped heated air at the ceiling of homes is a huge waste of money when trying to heat a building. Ceiling-fans which have reversible motors allow air to be pushed downward, lessening the need of the constant use of heating. Some advanced models of ceiling-fans feature controls which can adjust the temperature settings in each room.

Overall, ceiling fans can be a stylish and modern addition to any private home, business establishment, or office. They offer distinct looks which can transform the feeling of a room, from sleek contemporary minimalist fans to traditional styles which can give a space a welcoming feeling. For those who are on a budget or simply want to reduce their contribution to energy waste, ceiling-fans in addition to air conditioning services is the best option. HVAC service professionals are able to upgrade appliances to be more budget friendly over time by consuming less energy, and in conjunction with the use of a ceiling fan regularly you can find your heating and cooling bills to drop tremendously. Prices of ceiling fans vary greatly by the style, size, material, and finish chosen. However, no matter the cost of the new fan, it will soon pay for itself by saving you a great deal of cash each month on your electricity bill.

Air Conditioners, What Could Be More Important Than A Good Brand Name


A common misconception about air conditioning equipment is that Brand Name is the best indicator of quality. While it is true that some brands are better than others, this is not the main criterion you should use when making your buying decision. You may do yourself a great disservice if you overlook this.

The most important factor regarding central air conditioners and heat pumps, without exception, is the quality of the installation.

A high-end air conditioning system installed in an unprofessional manor, without regard for quality of installation or proper sizing will not perform any better than a low-end system installed with emphasis on the quality of the installation.

Furthermore, using the above example, the operating and maintenance costs associated with the high-end system may very well exceed that of the low-end system by a large amount over the life of the equipment.

These expenses will show in increased monthly energy costs, maintenance costs, and equipment breakdowns. There are also concerns about indoor air quality, and noise.

One of the benefits of a properly sized air conditioning system is humidity control. The operating characteristics of air conditioners is similar to dehumidifiers.

The evaporator coil temperature is below the dew point temperature when in operation. This results in moisture condensing on the evaporator and reduces the moisture content in the air. This results in lower humidity. The run cycles of an over sized air conditioner will be too short for this dehumidification process to occur.

The run cycles of an undersized system will be too long and may keep humidity levels too low. This system will loose a lot of its capacity to the dehumidification process and only cool effectively when humidity is very low.

Maintenance and repair costs can be higher than normal on an over sized air conditioner. There are components in air conditioners that require replacement from time to time because they wear out. For example the compressor contactor. The contactor is the device that operates the compressor. Each time the compressor starts, the contactor closes. The more often the compressor starts and stops the faster this part will wear out.

The compressor is another example. It is common knowledge the greatest amount of wear on a car engine is at start up. The same is true of an air conditioner compressor. There is oil in the compressor and each time it cycles off the oil drains from the bearings and gets picked up again at startup. Because there is less oil for lubrication at startup, this is when the greatest amount of compressor wear happens. If your air conditioner cycles on and off 4 or 5 times per hour instead of the normal 2 or 3 times per hour it only makes sense that this causes more wear on the compressor.

These are only some of problems associated with over sized and undersized air conditioning equipment. There are other complications that add to these problems and cost you more money. So when shopping for a new air conditioning system get more than one or two prices and make sure the contractor does proper load calculations so you can avoid these problems.
