Identifying and Understanding Common AC Noises


A buzzing noise often happens when parts of the AC are loose, or there’s an electrical issue. It might also be due to debris in the indoor or outdoor unit. These issues may cause both efficiency and performance to drop.


It’s normal to hear a clicking sound when your AC starts up or shuts down. However, continuous clicking could be a sign of a defective control or failure in the contactor relay switch, both of which require immediate attention.

Banging or Clanking

Banging or clanking often indicates a loose or broken part inside the fan or compressor. This is a serious issue that warrants immediate inspection for HVAC repair.
