Spooky Noises Coming From Your A/C?

With Halloween just around the corner, you may be a little on edge when you hear a bump in the night. One thing you don’t want is to hear spooky sounds from your HVAC system! In this post, we’ll take a look at some of the common scary noises that can come from your HVAC unit, and what you can do to stop them!

A loud, high-pitched screaming or screeching sound is likely a sign of a bearing or bad belt. If you’re hearing that banshee-like noise, get it fixed before it causes your whole system to shut down. The good news is that this is a relatively inexpensive repair.

A loud banging sound is more likely an issue with the assembly of the blower or motor. It’s possible that there are loose parts among your HVAC’s core components. It’s a good idea to have a professional check it. If everything seems connected properly, but you still hear a banging or clanking, it’s possible that the blower is not aligned. Regular maintenance is a good way to ensure this doesn’t happen to you.

Maybe it’s not loud banging you here, but just an occasional clicking. It is relatively common when the system turns off and on, and not usually anything to be worried about. However, if it’s more frequent, or seems to be coming from your control panel or compressor, it could be a problem with the electrical system causing a relay failure. These can be fixed by a professional HVAC technician.

Rattling is definitely a bad sign. This means you may have a loose fan or motor. Regular maintenance can prevent this from happening in the first place, but if it does, it’s an easy fix.

The final warning sound you may hear is smacking. This can come rapidly and may mean there’s something stuck in the blower blades! If that’s the case, it should be removed as soon as possible. If that’s the only issue, then the rest of the system should be in good shape.
