During regular vehicle operation, a significant amount of heat is generated by the engine, as well as exterior factors like the road and sun. Your car’s A/C system is responsible for combating these heat sources by cooling, purifying, and circulating air. It works through a series of processes involving refrigerant, which goes through a continuous cycle of air compression dependent on your A/C compressor’s drive belt. The compressor pumps the refrigerant through the system where it is transformed from a hot gas into a liquid and then cooled. Through several other components, such as the condenser, compressor, and evaporator, the liquid is again processed into a gas, pressurized, and vaporized before being released into your car as cool air.
