Most Common Causes
Grease-Laden Blower Wheel
Requires Service
Accumulated grease on the blower wheel creates imbalance and vibration, causing rattling or grinding.
Loose Duct Connection
DIY Possible
A loose duct joint can vibrate during operation, creating rattling sounds.
Dirty Baffle Filters
DIY Possible
Heavily soiled filters can rattle or whistle as air forces through restricted openings.
Other Possible Causes
Worn Fan Motor Bearings
Aging motor bearings create grinding or squealing sounds that worsen over time.
Backdraft Damper Flapping
A worn or broken damper flap can rattle during operation or in windy conditions common in Scottsdale.
