The A/C compressor is a type of pump that is powered by a belt connected to the vehicle’s engine’s crankshaft. When the A/C system is turned on, the AC compressor “compresses” the Freon from a gas state into liquid and pumps the refrigerant to the compressor and beyond. From there, the Freon goes to the condenser. The compressed Freon is pushed through the system under pressure and is passed through different sized metal and rubber hoses and a special valve called an expansion valve causing the gas to expand and contract.
This expansion and contraction makes the Freon gas very cold. This cold gas makes its way through the metal lines into the dash area of your automobile to the evaporator core. Then, a small fan sits in front of the evaporator core and blows air across this cold evaporator and then through the vents inside your vehicle. This is now the reason why you and your passengers are kept comfortable while inside your GMC.

The GMC AC compressor is the most important and the most expensive part of your GMC A/C system. Like the human heart, any complication or damage in your GMC AC compressor can largely affect how the entire A/C system functions. Therefore regular and proper maintenance is needed to make sure that it is always in good working condition. Even if GMC A/C compressors are lubricated with special oil and are equipped with safety switches to prevent internal damage, it will still break down in due course. When this thing happens, there are a lot of sources, both online and local where you can find replacement GMC AC compressors.
