Your air conditioner has several major components: the compressor and condenser reside in the outdoor unit, while the evaporator and air handler reside in the indoor unit. There is also an expansion valve between the condenser and the evaporator coils, not to mention the refrigerant itself, which is chemically designed to fluctuate between extreme temperatures when under pressure. Since the process is a cycle, it works constantly, so we’ll have to pick an arbitrary starting point: the compressor.

The compressor is the engine of your AC. Once it’s fired up by the capacitor, which acts a bit like a cross between a car battery and starter, it takes the low-pressure gaseous refrigerant from the evaporator coils and heats it up to a temperature greater than your outdoor air. When the refrigerant circulates through the condenser coils, the heat dissipates with the help of an exhaust fan into a hot liquid. The expansion valve controls the pressure flow, thus causing the liquid refrigerant to cool radically. Now it’s ready to interact with your warm indoor air that has been extracted by the indoor air handler. This thermal exchange causes the refrigerant to evaporator, once more turning into a gas for the next round of the refrigerant cycle. The result is cool air that is then returned through your ductwork and into your home. If you have a ductless system, then the indoor unit does all this work within the living space itself.
