If your AC blows warm air off and on, start with simple checks and then schedule a professional diagnostic. Intermittent warmth often traces to airflow, thermostat settings, or refrigerant issues.
Quick checks:
- Set thermostat to Cool and Fan to Auto.
- Replace a dirty filter.
- Make sure supply and return vents are open.
- Check the breaker and outdoor disconnect.
- Ensure the outdoor unit is running and coils are clear.
- If you see ice on lines or coil, turn system off and call.
