Why is My Air Conditioner Making so Much Noise?

If the noise your air conditioner is making is unusual or is different from its regular hum, there are a few things to consider.

How would you describe the unusual noise that your unit is making?

  • Rattling
  • This could be from something that fell into the vents, or something is loose, a bolt, screw or fastener. It could also be your compressor rattling. If it is your compressor or anything more serious than a loose bolt you will need a technician to look into the problem further.

  • Grinding
  • Most likely this is one of the fan motors, or it is possible that there is a worn bearing.

  • Popping
  • This noise might be coming from your ductwork when your AC unit turns off and on. This usually indicates a problem with your duct work and not necessarily a problem with your central air. Ductwork ages just the same as anything else and requires routine maintenance to make sure it is functioning effectively.

  • Hissing
  • Unless this noise is coming from your ductwork (a common problem), this could possibly be a refrigerant leak. If that is the case you will need one of our technicians to handle the problem.

Your air conditioner is a piece of machinery with many moving parts and, like a car, it requires regular maintenance by experienced professionals to diagnose and treat problems.
