Get Familiar with the Main Components of Your Central Air Conditioner

Last updated 2 years ago

If you’ve installed a central air conditioning system in your Atlanta-area home, you already appreciate its efficiency and cooling power. You may not know how it works, though. Your central air conditioner it isn’t as complex as you might think. Keep reading to learn about the operational basics of your system. This knowledge may pay off if your central air conditioner requires future maintenance.

Refrigerant, Ductwork, and Thermostat
Your system keeps your home cool by circulating a compressed air refrigerant, which cools and dehumidifies your interior air. The refrigerant absorbs heat and emits cold. In the process it must repetitively change from a liquid to a gas. The refrigerant is circulated between the internal and external components of your system through copper tubing. Air is distributed throughout your home via a channel of ductwork and the temperature is controlled by a thermostat. The system then expels heated air outside of your home.

The Blower and Evaporator
The blower circulates your internal air and the evaporator cools it. Heated air in your home is drawn through a return-air duct into the evaporator, located just above your furnace. There, the blower pushes the heated air over the evaporator’s cooling coils. The blower then distributes the newly cooled air back throughout your house again via the ductwork.

The Condenser
The condenser is the heart of your central air conditioning system. This unit is usually located outside of your home, anchored to a concrete slab. Inside of the unit is a pump called a compressor. The compressor pumps refrigerant throughout the entire circulating system. The condenser also contains a fan and coil that together expel heated air from your home.

Your central air conditioning system should be professionally inspected and adjusted before the beginning of every cooling season. Your condenser unit is hermetically sealed so that condensation doesn’t damage it. Therefore, you should not attempt to access your system’s components in case it requires repair. Instead, leave all of your central air conditioning system inspection and repair issues in the hands of the professionals at Estes Heating & Air Conditioning.
