![]() If you hear squeaking or squealing sounds from the. Over time, you may notice your A/C not performing as it should. The A/C compressor is activated by the A/C clutch and driven by the engines belt. ![]() This pressure pushes the refrigerant through the rest of the system. ![]() Hybrid vehicles use POE (polyol ester) oil, because it is non-conductive, and older vehicles use mineral oil. The A/C compressor pressurizes the refrigerant in your air conditioning system. A/C Repair 384 to 445 A/C Compressor Replacement 1,546 to 1,705 A/C Recharge 239 to 281 This data is based on Kelley Blue Book’s Fair Repair Range. Most vehicles use PAG (polyalkylene glycol) oil, though some vehicles may use PAO (Polyalphaolefin) oil. ![]() Hybrid vehicles use a high-voltage electric motor to run the air conditioning compressor.Ĭirculating with the refrigerant, lubricant protects moving parts and maintains seals. The belt-driven fixed-displacement compressor is cycled by an electromagnetic clutch, while constant-running variable-displacement compressor output is controlled internally. Sensors detect pressure and speed, and seals keep lubricant and refrigerant from escaping the system. The air conditioning compressor is a compact unit, with inlet and outlet ports, internal pistons and valves, and a shaft to move the swash plate and pistons. Compressor service may be required if you are experiencing problems with your air conditioning system. The air conditioning compressor is the most critical component in the system, pressurizing the refrigerant and circulating it through tubes, hoses, evaporator, and condenser. L A Automotive's pro mechanics know that even the smallest gaps can cause serious damage to your car's cooling system and engine.The air conditioning system is nearly essential for a comfortable ride in any humid Missouri Summer and improves visibility by defogging windows in the Winter.
