We hate to be the bearer of bad news, but well-functioning air conditioning units are almost silent, and strange noises coming from your AC are never a good sign. Let’s walk through some possible reasons why your metro Atlanta area home’s unit might be noisy, and learn if it might be smart to call in the experts for AC maintenance or a repair.
1. Clicking
YES
Some clicking is normal when your system is turning on or off, but if it becomes constant, an electrical malfunction could be the issue, and we recommend contacting an experienced air conditioning technician to avoid the risk of an injury.

2. Buzzing
YES
Buzzing can be linked to a wide variety of potential issues. You can check the unit for sticks or other debris and replace the air filters, but if that doesn’t fix it, it could be something more serious like a loose part, a dirty condenser coil, or even a refrigerant leak, and you’ll want to call an AC tech for help.

3. Squealing
YES
Our ears usually have good instincts about the difference between a normal squeal and a problem squeal. If you hear an unsettling squeal coming from your AC, it could be caused by a problem with the outdoor fan or indoor blower, which requires a professional fix.

4. Rattling
YES
Rattling sounds could mean anything from a loose screw to a loose part. Start by checking your outdoor unit for sticks and other items that may have gotten caught in it. If there’s nothing there, it could be a sign that your compressor is dying.

5. Banging
YES
If your AC is making a banging noise, it could mean that a part has come loose. While a loud banging noise can be very jarring, it can give you a clue to how big the loose item might be. It’s a good idea to shut your unit off and call a professional service technician as soon as you’re aware of the sound to prevent the loose part from damaging other parts.
