Intermittent warm air usually means an airflow or component issue that needs diagnosis. Cole Services offers a $79 A/C Diagnostic with 2-hour arrival before 2:00 PM, or a $59 A/C Repair Diagnostic with same-day service in cities like Anaheim and Garden Grove. We diagnose on site, explain options up front, and can fix most problems immediately.
Quick checks:
- Set thermostat to Cool and fan to Auto.
- Replace a dirty air filter.
- Check that the breaker isn’t tripped.
