Why Is My Air Conditioner Making a Humming Noise?

Top Causes of Air Conditioner Humming Sounds

Is your air conditioner making a humming noise somewhere on the inside? It could be that the condenser fan motor is seizing up or that the contractor relay switch is malfunctioning. Or maybe some miscellaneous parts have loosened up over the years or gotten covered in a layer of ice? Otherwise, if your circuit breaker is being overworked, it can sometimes trip and cause the air conditioner to start humming too.

3 Other Types of Air Conditioner Noises and How To Fix Them

There are other noises your air conditioner can make (besides humming) to indicate that things aren’t working properly. Here are a few of the biggest ones to keep your ears peeled for.


A light hissing sound is normal with air conditioners, as air is rushing through them whenever they operate. However, if it’s very loud, or if there’s a gurgling sound too, you could be dealing with a cracked or leaking tube that’s allowing air to escape out.


Are you hearing a whiny, screeching noise being emitted by your AC system? Can you tell if it’s occurring while the AC is starting up or running? If so, alert the Fenwick technical team on what you’ve noticed so we can determine whether it’s the compressor, fan motor, bearings, or something else causing the noise.


While it can be a little jarring, any rattling that’s coming from your AC could just be a loose door or part. Really, this is more of an annoyance than a threat to your system. If you don’t see anything when you inspect it, get in touch with us. It could be that something is inside your ducts or that your fan blades are bent.
