Possible Causes
Improperly adjusted dampers, Blocked ducts, Undersized branch ducts, Dirty filter restricting overall flow
How to Fix / Troubleshooting
Safety: Ensure the furnace is off before reaching into ducts.
Steps to check:
- Open all registers: Confirm supply registers in cold rooms are fully open.
- Adjust dampers: If manual dampers are installed on trunk lines, adjust them to direct more air to colder zones.
- Filter: Replace a dirty filter to restore full airflow.
Persistent imbalance may require duct modifications or zoning by an HVAC professional.
