Air Conditioning Compressor

By David Sturtz, April 15, 2008

The air conditioning compressor pumps in refrigerant gas from the receiver/drier, compresses it, and sends it to the condenser.

Symptoms of a Bad or Failing Air Conditioning Compressor

  • Weak cool air from system (or no cold air at all)
  • Loud noises when using the AC

Air Conditioning Compressor Related Repair Advice

  • The AC system should be operated at least once a month—even during the winter—to circulate the refrigerant and oil
  • Most modern vehicles operate the AC compressor in the defrost mode. Air circulating through the system is naturally dehumidified, which helps in the defrosting process
  • Moisture collects and is drained from the heater/AC case, often showing up as a puddle of clear fluid under the vehicle
  • An AC compressor may need to be replaced if it's found to be leaking oil and/or refrigerant
  • We recommend replacing the AC accumulator or drier when the AC compressor is replaced. The accumulator acts as a moisture and debris filter for the AC system—a new part will keep the repaired system clean.
  • Any restrictions in the AC system will need to be identified and repaired or a recurring problem with the AC compressor is likely

The air conditioner went out on our 2010 Honda CRV in 2014. Are there any recalls re: this issue? We paid $26,000 for this car and we have had so much trouble. Now, we have a 7 year old Crv with no air and it won't run now either. Any help???

I have a Briggs & Stratton Quiet Power Air compressor from https://bestaircompressorstore.com/best-quiet-air-compressor-reviews-2017-2018/ 4 gallon air compressor. I have got the highest service from it. But I need to repair it as soon as possible. But I have no experience with it. After reading this article I believe this article must help me.
