The air conditioning (A/C) system of your vehicle works just like the A/C system in your home or office. Auto A/Cs share the same parts: evaporators, condensers, receiver dryers, and compressors. The only difference there is, so far, is that automotive A/C parts are in a linear configuration, with the A/C compressor in the middle, acting as the heart of the system.
Your auto A/C compressor compresses the refrigerant, usually Freon gas, which is then transferred from the low-pressure side to the high-pressure side of the A/C for heat dissipation. The A/C is a closed-loop system; it's where the cooling process starts and ends-from the evaporator to the compressor to the condenser. The A/C compressor greatly determines the cooling ability of the A/C system, so it's a must to have a quality one to ensure that air inside your vehicle is cool.
The auto A/C compressor is among the most replaced parts of the A/C system. Whenever you have problems with the air discharge from your A/C, have the mechanic inspect the compressor first. And to guarantee that you enjoy better function of your air compressor, we recommend that, in case the need calls for it, get only a high-performance replacement.
