What should I do if my AC is blowing warm air intermittently?
Intermittent warm air usually points to airflow, refrigerant, or thermostat issues. Start with these quick checks:
- Set thermostat to Cool; fan to Auto.
- Replace the air filter.
- Clear debris from the outdoor unit.
- Check the breaker once.
- If lines are iced, turn system off to thaw. If it persists, we will test refrigerant, clean coils, clear drains, and repair thermostats with 24/7 service and upfront pricing in Carmel, Fishers, and Noblesville.
