It’s normal for your air conditioner in Abbeville, Louisiana, to make sounds as it turns on and off. But if it does more than hum at a low decibel while it operates, there’s probably a problem causing it. Waiting to repair the issue can cause more damage and even result in the need for a replacement. Here are three strange sounds your air conditioner can make that signal trouble:


Do you hear a banging sound when the air conditioner’s outdoor unit operates? If the sound doesn’t occur when you turn the thermostat to FAN, there’s likely a loose fan hitting something. The outdoor compressor might also have an obstruction like a branch in it. Continuing to run the AC system could cause further damage, so turn it off.


You’ve stepped outside only to hear your air conditioner’s outdoor unit screeching. It sounds like metal-on-metal contact, and it isn’t pleasant. If you hear this strange sound, it’s likely that your AC system has damaged fan motor bearings. You can continue to run your unit if needed, but you’ll want this issue repaired right away.


If you notice a squealing sound when your air conditioner operates, it likely has a misaligned or worn fan belt. The sound might come and go, but the problem is always there. You can continue to operate your air conditioner, but the belt will eventually break. As a result, you’ll be left with cooling and need an emergency repair.

These are just a few of the strange sounds your air conditioner can make during the cooling season. If your AC system is making banging, screeching, squealing, rattling or knocking sounds, don’t wait to get it fixed.
