Your heat pump is likely running but not cooling because of one or more common issues: a dirty filter, low refrigerant, a miscalibrated thermostat, blocked outdoor unit, or a clogged condensate drain. Our Dayton, OH technicians routinely check these during tune-ups, including refrigerant levels, thermostat calibration, filter service, coil cleaning, and electrical connections.
Quick checks:
- Replace or clean the air filter.
- Clear leaves/debris around the outdoor unit (2–3 feet).
- Set thermostat to Cool and verify temperature setpoint.
- Look for water around the air handler (possible drain clog).
