Even though fall is finally here, Southern homeowners may still be using their air conditioning units for comfort and safety. While your system is bound to make a bit of noise when running, certain sounds might mean trouble. Here’s a closer look—or listen—at which noises indicate it’s time to call an HVAC contractor for AC repairs before you switch to heat this fall. 

What Sounds Mean Air Conditioning Unit Problems?

1. Banging

A banging, clanging, or loud knocking that’s metallic in nature often occurs when an internal component is broken or loose and striking the unit’s blower fan. This needs to be addressed in a timely manner to prevent damage to the compressor or blower. These crucial parts are expensive to repair and may lead to the full unit needing to be replaced.

2. Gurgling

A gurgling or bubbling sound is often linked to a faulty compressor line. The noise is created as refrigerant leaks out of your unit and has trouble draining properly into your drain line. Without a coolant supply, the system won’t be able to provide cool air. A technician will find the leak and replace the line.

3. Click

While a gentle hum may occur when your system starts running, a constant clicking sound that occurs as you first turn your unit on is generally a sign of an obstruction impacting the outdoor fan. Start by inspecting the exterior of your compressor and removing any potential obstructions. If the clicking continues, have a technician perform a further inspection inside the unit.
