Banging
If you ever hear a loud, banging noise coming from your air conditioner Mesa AZ, you can be sure something is either broken or loose.
It can be anything from a piston pin, connecting rod, or a crankshaft inside the unit’s compressor. Sometimes it means that the indoor blower is out of balance.
Banging can also indicate the need for the entire compressor to be replaced.
Clanking
Clanking also indicates that there are out-of-balance or loose parts inside your AC unit. The compressor may be loose, or inside parts have failed.

Clicking

However, if there are persistent clicking noises when the AC is running, it might indicate a failing thermostat or defective control switches.
