Why Is My AC Running But Not Blowing Cold Air?

Your AC often runs but won’t cool due to airflow, refrigerant, or control problems. Typical culprits: clogged filter, dirty outdoor coil, iced evaporator, low refrigerant from a leak, failed capacitor or fan, or thermostat set to On instead of Auto. We offer 24/7 diagnostics and repair in Chesterfield and greater St. Louis. Maintenance plans help prevent repeat issues.

  • Set thermostat to Cool and Auto.
  • Replace a dirty filter.
  • Clear debris around the outdoor unit.
