How Does an Air Conditioner Work? All of this talk about different sizes, systems, benefits and features can make an air conditioner seem more complicated than it essentially is. Understanding how an air conditioner works can help shed light on why your system needs regular attention and how it actually goes aboutThis is a story of your refrigerant's journey though a series of coils that eventually end up removing the heat from the air in your home. 1. The Journey Begins Your lineset connects your outdoor air conditioning condenser to your indoor air handler, or furnace and coil. Liquid refrigerant moves into the home through the lineset and into the evaporator/indoor coil.. 3. Where the Magic Happens The liquid refrigerant goes through the evaporator coil while warm, indoor air is blown across this coil. Heat is transferred from the warm air stream into the refrigerant – resulting in cooler indoor air and the evaporation of the liquid refrigerant into a gas.

4. Receiving the Cool Air The blower, located in your air handler or furnace, blows the cooled air through a series of ducts in your home.. 5. The Other Coil The refrigerant gas returns to the outdoor air conditioning component where it is pressurized, by the compressor, and then pumped into the condenser coil. The condenser coil works similarly to the evaporator coil, but in reverse. Air is passed over the condenser coil, which results in warmer air that is blown out of the condenser/air conditioner and refrigerant that is changed from a gas to a liquid. 6. Back to the Beginning The process is repeated until your home reaches the set temperature. Your air conditioner has a lot of components that are vital for maintaining cool temperatures routine preventative maintenance an important part of owning anDuring preventative maintenance, your contractor can check the different parts and make sure that they are doing their part is this cyclical process.
