How To Install An AC Compressor

What Does an AC Compressor Do?

The AC compressor serves the purpose of converting the low-pressure refrigerant into a high-pressure refrigerant and sends it to the condenser. It is the central component that maintains the pressure difference between the high-and low-pressure sides of the AC mechanism. Proper lubrication is essential to prevent the compressor from premature wear. A bad compressor, of course, will not send the refrigerant under the required pressure, thereby failing to provide optimal cooling to the vehicle.
