What could cause my AC unit to make strange noises?

I understand how worrying it can be when your AC unit starts making strange noises. There are several potential causes for this issue, some more serious than others.

One common cause could be a loose part inside the unit. Over time, screws or bolts can come loose due to the constant vibrations of the AC unit running. When this happens, it can create a rattling noise that’s quite annoying. This is something a Loveland AC repair professional can fix for you.

Another possible reason could be a dirty or clogged air filter. When the filter is blocked, the air can’t flow smoothly, causing unusual sounds. It’s a good idea to check and see if your filter needs cleaning or replacing.

You might also want to check if the blower fan is damaged or off-balance. When the fan isn’t working properly, it can make a banging or squealing noise that’s hard to ignore. Sometimes, this just needs a bit of adjustment, but it could also mean a part needs replacing.
