What should I do if my AC is blowing warm air intermittently?
Intermittent warm air usually means an airflow, control, or icing issue. Try a few quick checks, then schedule service if it continues.
Quick checks:
- Set thermostat to Cool/Auto; replace batteries.
- Replace a dirty filter; open all vents.
- Clear leaves/debris from the outdoor unit.
- Reset any tripped breakers.
- If lines are iced, turn system Off and Fan On.
