What should I do if my AC is blowing warm air intermittently?

Intermittent warm air usually means a thermostat issue, airflow restriction, or dirty outdoor coils. Do a few quick checks before calling.

  • Set thermostat to Cool and a lower temperature.
  • Replace/clean the air filter to restore airflow.
  • Open supply vents and remove blockages.
  • Clear leaves/debris around the outdoor unit and gently clean coils.
  • Power the system off for 5 minutes, then test again.
