Air conditioners are wonderful appliances that keep homes cool on sizzling summer days. However, few people know how they operate. Understanding how air conditioning works can help homeowners identify potential problems before they become costly repairs.

The heating and cooling professionals at Purvis Heating & Air Conditioning in Fitzgerald, GA, have been servicing and repairing air conditioners for more than 40 years. They explain how air conditioning takes heat from the interior of a building and expels it outside:

Warm air is sucked into a grille at the bottom of the machine and fed through chiller pipes that cool the air. The chilled air is then pushed back into the room through another grille while warm air is pushed outdoors by an electric fan.

Air conditioners consist of five main parts to perform this function: refrigerant, condenser, compressor, expansion valve, and evaporator coil. The refrigerant, which is pumped through the unit by the compressor, changes air from a gas vapor to a liquid. The refrigerant goes through the condenser, which cools the air, converting it to liquid form. From here, the expansion valve takes over, transforming the liquid into a low-pressure mist. This mist travels through the evaporator coil, changing back into a vapor before releasing into the interior of your home as cool air.

If any of these parts fail, you can experience warm air instead of cold, a unit that doesn’t turn off, or a complete break down of your HVAC system. When this happens, homeowners in 19 Georgia cities can rely on Purvis Heating & Air Conditioning for a fast and efficient air conditioner repair. The company also offers maintenance plans to provide routine service for air conditioners of all makes and models.
