Why Is My AC Running But Not Cooling Properly?

If your AC runs but won’t cool, airflow or refrigerant issues are most common. Typical causes include a dirty filter, a blocked/dirty outdoor coil, low refrigerant from a leak, a frozen evaporator coil, duct leaks, or incorrect thermostat settings. We serve Marion and nearby communities and can diagnose and fix the root problem.

Quick checks:

  • Replace the air filter.
  • Clear debris from the outdoor unit.
  • Set thermostat to Cool/Auto.
  • Open supply and return vents.
