What Do Common HVAC Noises Mean?
New banging, grinding, screeching, buzzing, repeated clicking, or rattling deserves investigation. Stop for smoke, burning odor, or severe vibration.
Check HVAC for Sounds
Something just doesn't sound right. Listen to your outside HVAC equipment when running. Listen for strange sounds: squels, rattling, etc. These strange sounds can turn into big repair bills.
Why rattling?
Panels, debris, ducts, or worn parts may contribute.
Why squealing or grinding?
Belts, bearings, blowers, or motors may be involved.
Why repeated clicking?
Controls or failed starts are possibilities.
When turn power off?
For smoke, burning odor, breaker trips, or severe vibration.
