Why Is My Heat Pump Running But Not Cooling Properly?

Heat pumps often run but don’t cool because of airflow restrictions, low refrigerant, or control issues. Typical causes include dirty coils, clogged filters, debris at the outdoor unit, thermostat miscalibration, loose electrical connections, a blocked condensate drain, or an incorrect defrost setting. Summers Plumbing Heating & Cooling can diagnose and tune your system in Elkhart, including cleaning coils, checking refrigerant and leaks, tightening connections, calibrating the thermostat, and clearing the drain. We also recommend professional maintenance twice a year for reliable heating and cooling.
