1) Uneven temperatures between rooms
If some rooms are too warm while others are too cold, your system may be struggling to distribute conditioned air properly.
This can come from duct leakage, blocked returns, airflow imbalance, or declining equipment performance.
- Rooms farthest from the unit feel uncomfortable first.
- Second floors often show stronger imbalance during seasonal extremes.
- Thermostat setpoint may be reached while key rooms remain uncomfortable.
