Auto air conditioning is one of the great inventions of the modern age, keeping your car comfortable through even the hottest summer weather. Since Packard introduced the first automotive AC system in 1940, air conditioning has become ubiquitous, with almost every new car and truck sold in the U.S. equipped with an air conditioning system. While the overall look has changed dramatically over the years, the basic design has remained unchanged.

Every AC consists of three primary components that remove humidity and cool the air: the compressor, the condenser, and the evaporator. Essentially, your auto air conditioning works by pressuring a refrigerant, which is a gas in its natural state.

From there, the compressor forces the gas into the condenser, which acts as a type of radiator. Inside the condenser, the pressurized gas becomes a liquid, dissipating heat into air rushing through the coils.

As the highly pressurized liquid refrigerant enters the evaporator, it passes through a reservoir known as the receiver-dryer, which removes any water that has penetrated the system. The evaporator, usually located somewhere in the cabin, reduces the pressure of the refrigerant, allowing it to become a gas again that absorbs heat and returns to the compressor, where the process restarts. At this stage, air forced over the evaporator’s coils creates the cool air that fills the passenger compartment and provides welcome relief from the heat.
