The air conditioning compressor may develop an abnormal noise and require replacement. We recommend that whenever an AC compressor is being replaced for a noise condition, a filter kit should be installed to prevent any metal particles in the system from damaging the new compressor.Google+

AC compressor clutch turns on really hard, then the AC system completely died due to Freon leak internally in AC compressor. Replace AC compressor/dryer and recharged system.

Replaced the A/C clutch unit at 350,000 and later the noise that was spoken off did occur. Now have a new compressor and its working great.With the new compressor warranty,I had to purchase a new expansion valve and new accumulator. As well I had to pull a vaccumm on the entire A/C system and replace the oil and refrigerant gas.
