Why Is My Heat Pump Running But Not Cooling Properly?
Common causes are a dirty air filter, a blocked outdoor unit, or thermostat settings not set to Cool. Harker recommends checking and replacing filters every 1–3 months and keeping the outdoor coils and airflow clear. We offer 24/7 emergency support for heat pump issues. Harker Heating & Cooling serves Madison and Sun Prairie.
Quick checks:
- Set thermostat to Cool and lower the setpoint.
- Ensure vents are open.
- Clear leaves/debris from the outdoor unit and gently rinse coils.
- Replace a clogged filter.
- If icing or poor airflow persists, schedule service.
