When the compressor is off, it’s usually quiet. But every once in a while, it might throw a sonic curveball at you. Here are some of the possible noises and what they might mean.
Common Types of AC Compressor Noises When Off
A symphony of sounds can come from your AC compressor when it’s off – and not all of them are music to your ears. Here’s the lowdown on some common noises.

Banging or Clanking Noise
If it sounds like there’s a blacksmith at work in your AC unit, you might have loose or broken parts in the compressor. It’s like a tiny metallic concert that you definitely didn’t sign up for!

Hissing or bubbling noises might mean there’s a refrigerant leak. Picture a soda can that’s just been opened, that hissing sound? Yeah, not ideal for your compressor.
