Why Your AC is Loud

Air conditioners can make a variety of different noises. But when you hear a loud buzzing or rattling noise coming from your unit, you know you’ve got a problem on your hands for a professional to come and fix. But what exactly is the problem?

Here are a few reasons why your AC might be making a loud sound:

Debris – It’s easy for dirt to get caught in your window AC or outdoor HVAC unit. A loud rattling noise can be a sign of debris in the fan. If this is the case, you should turn off the system immediately and call a technician to repair the problem.

Ductwork – Sometimes a hissing sound can be caused by an issue with your ductwork. There may be cracks due to old age or improper installation. Damaged ductwork can prevent your home from cooling optimally, so it’s important to fix the problem right away.

Leak – Hissing can also be a common sign of a refrigerant leak. That is, if it’s coming directly from the AC unit. Leaks can worsen if you try to fix the issue on your own, so don’t be afraid to grab the phone and call your HVAC pro to help you out.

Compressor – Do you hear a rattling sound? If so, it could be coming from your compressor – a sign that it’s reaching it’s old age. If your compressor is past it’s guaranteed lifespan, it might be time to replace it.
