3 AC Noises That Should Concern You in Kinston, NC

Our residential and commercial customers in Kinston, NC, sometimes report hearing loud noises coming from their air conditioner. While loud noises can often signal a serious problem, hissing and other quieter sounds can also be cause for concern. If your AC system is making any of these three noises, schedule an air conditioner repair right away:


If your air conditioner’s compressor has come loose, you’ll hear clanging sounds. Most of the time, fixing the problem is as simple as adjusting whatever has come loose. If there’s enough damage to whatever is clanging around, though, you’ll have to pick up a replacement component. Always seek professional guidance for air conditioner repairs and replacements.

Bangs and Pops

It can be tough to tell the difference between loud banging and the clanging noises described above, but they both signal that something is wrong with one of your AC system’s components. Banging noises coming from your AC system are usually a clue that something’s broken instead of just loose or out of balance. If you hear banging or constant popping noises, turn the power to your system off until a service technician can diagnose and resolve the problem.

Whistling or Hissing

Refrigerant leaks cause high-pitched whistling noises, and gas leaks cause hissing noises that sound slightly different. Either way, whistling or hissing noises are nothing to ignore. Shut off your system before things get more dangerous, call an HVAC professional and don’t use your air conditioner until a qualified service technician says it’s safe to do so.

If you’re concerned about some of the noises coming from your air conditioner, the worst thing you can do is ignore your instincts. A loose or broken part can shorten your system’s lifespan, so be proactive about looking for solutions. Contact J & J Mechanical to speak with one of our experienced service technicians and schedule your AC repair appointment as soon as possible.
