Why Is My AC Running But Not Cooling The House?

A Quality HVAC Services LLC most often finds an AC running but not cooling due to airflow restrictions, low refrigerant, or a control issue that lets the blower move air without real heat removal. The most common trigger is blocked airflow, which can cause coils to get too cold and stop transferring heat. Electrical or thermostat faults can also keep the compressor from starting, and a clogged drain or iced coil can halt cooling altogether. Our technicians handle these issues daily across the West Valley, including homes near Youngtown.

Before you call, these quick checks can help:

• Make sure the thermostat is set to Cool and the filter isn’t clogged.
• Look for ice on the refrigerant line or water at the air handler; if present, turn the system off to thaw.
• If the outdoor fan spins but the compressor never hums, or a breaker trips again, stop and schedule service.

Shut the system off if you see icing or repeated breaker trips to prevent damage.
