The AC compressor is one of the most important, if not the most important, components of a vehicle’s air conditioning system. It is responsible for pressurizing the AC system and keeping the refrigerant flowing so that it can function properly. Because it functions in a continuous cycle on and off, it is subject to wear every time the AC is turned on. Just like any other component on a vehicle, it will eventually fail and need to be replaced. Usually when a compressor begins to fail it will produce a few warning signs that alert the driver that it has a problem.
