Improperly sized supply ducts, Closed or unbalanced dampers, Leaky return ducts, Blower speed not matched to duct system
How to Fix / Troubleshooting
Safety first: Turn OFF power before opening duct access panels.
- Check registers: Ensure all supply registers are open and not blocked. Adjust dampers to balance airflow between rooms.
- Inspect return ducts: Look for disconnected or leaking return ducts, especially in basements or attics. Seal with mastic or UL-listed foil tape.
- Filter type: Avoid overly restrictive filters that can reduce airflow and worsen distribution.
- Professional duct assessment: An HVAC contractor can measure static pressure and adjust blower speed or recommend duct modifications for your Kelvinator furnace.
