Common Causes of Strange Noises in AC Systems
The typical hum of operation and the occasional chirping are the only sounds your AC should be making. If you hear anything else, you have a problem requiring repair or replacement.
Here are the most common sounds you’ll likely hear:
- Squealing usually means a fan belt problem that will only get louder until it’s fixed.
- Clicking is more serious than it sounds. A clicking could indicate a potentially dangerous issue with the unit’s electrical system that you don’t want to get worse.
- Buzzing, similar to the vibration of an electric toothbrush, is another sign of a potential electrical problem. Buzzing usually indicates loose wiring, the condenser fan motor, or the contactor relay switch.
- Rattling, banging, or clanking noises can have many causes ranging from twigs or leaves caught in your system to parts becoming loose as your AC nears the end of its service life.
- Hissing or bubbling sounds usually occur when the refrigerant your system needs for cooling is leaking out.
When To Call for Repair
In addition to the above noises, you should also call if you notice:
- Unpleasant or unusual smells
- Weak air from vents
- Warm air
- Inconsistent heating
- Frozen components
- Constant switching on and off
- Unit can’t meet or maintain thermostat settings
Basically, anytime your AC acts strangely or doesn’t perform as well as it should, you need air conditioning repairs. You don’t want to regret putting it off after a small, fixable problem leads to significant damage or a system breakdown.
