What Should I Do If My Air Conditioner Is Running But Not Cooling?

If your air conditioner is running but not cooling, try these quick checks before scheduling service.

• Set the thermostat to Cool and a lower temperature.
• Replace a dirty air filter.
• Clear 12–24 inches of airflow around the outdoor unit.
• Verify breakers and the outdoor disconnect are on.
• Look for ice on the refrigerant lines; turn the system off to thaw.
• If it still won’t cool, we offer 24/7 diagnostics and repair in Boise and Nampa.
