Temperature varies significantly between rooms, some rooms don't cool properly
Fix Steps:
1
Check and clean all air registers and vents - ensure none are closed or blocked
2
Balance airflow by adjusting dampers in ductwork (requires access to ducts)
3
Verify return air vents are not blocked by furniture or curtains
4
Check filter is clean - dirty filter reduces airflow to distant rooms
5
Inspect ductwork for leaks, especially in unconditioned spaces like attics
6
Ensure all rooms have adequate return air path (gap under doors or transfer grilles)
7
Close vents partially in rooms that get too cold to redirect air
8
Check insulation levels in attic and walls of problem rooms
9
Verify thermostat location is central and not near heat sources
10
Consider zoning system if temperature variance is severe
