Why Is Your AC Making Noise?

Your AC has developed new sounds – grinding, squealing, rattling, or banging. The outdoor unit is louder than usual. Strange sounds when starting up or shutting down.

AC noises aren't just annoying; they're your system telling you something is wrong.

Common Causes of AC Making Noise

Grinding or Squealing

Often indicates bearing failure in motors – the fan motor in either the indoor or outdoor unit. Left unaddressed, this leads to motor failure.

Rattling or Vibrating

Suggests loose components, panels, or mounting. Sometimes simple to fix, but can indicate more serious internal issues.

Clicking Repeatedly

Clicking during operation (not just at startup) may indicate electrical relay problems or a failing thermostat.

Banging or Clanking

Serious – often indicates a loose or broken component inside the compressor. Continuing to run the system can cause expensive damage.

Bubbling or Gurgling

Suggests refrigerant issues – either low refrigerant or air in the lines.

Hissing

May be a refrigerant leak or simply high-pressure air movement, but should be checked by a professional.

What You Can Check Before Calling

Before calling a technician, check these simple things that might solve your problem without a service call:

Thermostat Settings

Ensure it's set to cool mode and the temperature is set below room temperature.

Filter Condition

A heavily clogged filter restricts airflow. Check and clean or replace if dirty.

Power Supply

Check that the unit is receiving power – breaker hasn't tripped, plug is secure.

Outdoor Unit

Ensure nothing is blocking the outdoor unit and it's running when the AC is on.
