Running an AC unit all summer is one of the highest costs that a homeowner has to contend with. Thus, you should do everything you can to prevent your home from heating up in the first place and run the most efficient AC unit you can find. With all the AC units on the market, you might be wondering what makes one unit more efficient than another. There are at least three key components to pay attention to.
An AC unit will have two sets of coils, and each set of coils will have a dedicated fan. The evaporator coils, cool your house by pushing the warm air from your house over the coils. This air heats the refrigerant running through the coils, which causes it to evaporate, and as it does, it absorbs heat from the air. The heated refrigerant than cycles out to the condenser coils, which blow the relatively cool outside air over the refrigerant to cool it back down to the point that it condenses back to a liquid. The larger the coils are in your unit, the more rapidly they can perform their function. Thus, look for a unit that has the largest coils for the money.
Your unit uses a compressor to pump the refrigerant through your system. If your unit only has one compressor, it will have only one capacity—full blast. Modern AC designers will use two compressors of different sizes to give your unit the ability to adapt the cooling to the needs in your house. It will use the smaller compressor when the need for cooling is low, switch to the larger as the need for cooling increases, and then use both when the need for cooling is at its peak. Thus, ask whoever you buy your unit from to make sure that you are getting multiple compressors.
Variable Speed Fan
The last component to pay attention to is the fan motor. You want a unit that has a variable-speed fan so that it can match its output to the output coming form the compressors. A variable-speed fan motor is a small thing that can make a big difference.
When you set out to buy an air conditioning system for your house, your best bet for making an informed decision is to know what components you absolutely have to have in your AC unit. If you start with the components described above, you should have no problem buying a unit that will help you to keep your cooling costs as low as possible.
Hi, my name is Melinda, and when I sold my home three years ago, I realized that I should have been keeping maintenance records. Because I couldn't prove that we had maintained our HVAC system, the home was actually harder to sell than it should have been. I don't want anyone else to lose money on a home sale or to experience the stress of not having the right records. Because of that, I have created this blog. It explains everything you need to know about maintaining normalcy with your HVAC system and keeping records of check-ups and repairs. Please, take a seat and enjoy reading this blog.
