In the middle of summer, when it’s hot and humid outside, all you have to do is flip on your air conditioner and you can relax in your cool and comfortable home. But have you ever stopped to think how your air conditioner works?
It’s extremely important to understand the mechanics behind your AC unit. If you become familiar with the basic process that cools your home, you’ll be more comfortable when it comes time to service your air conditioner and be able to ask the right questions of your HVAC (heating, ventilation and air conditioning) professional.
Heat Transfer is the Key
Air conditioners work by transferring heat; heat is removed (transferred) from the air in your home, leaving you with a comfortable environment. So, technically, your AC doesn’t increase cold air, it decreases hot air. To achieve this heat transfer, your air conditioner works by utilizing two major components—the indoor unit and the outdoor unit.
The indoor portion of your AC is called the evaporator and is usually located near your home’s other major home comfort component, the furnace. Inside the evaporator are coils filled with refrigerant that works to evaporate and absorb heat. Once the heat is absorbed, you’re left with cold and refreshing air in your home.
The compressor, condenser coil and fan make up the outdoor component of your central air conditioner. Once heat is absorbed into the cooling liquid indoors, it’s then pumped outside where it moves through the compressor. The refrigerant travels from the compressor to the condenser and the fan quickly cools the coils. The process is completed when the indoor heat is exhausted outside. Then, the refrigerant is pumped into your home to begin the process over again.
Understanding how your air conditioner works is important, but it’s also imperative to keep up with yearly maintenance for your cooling system. With so many different components working together to cool your home, it’s easy for a part to wear down and force a complete system breakdown. A professional heating and cooling technician can spot problems before they turn into an expensive air conditioning repair bill.
