Why Is My Heat Pump Running But Not Cooling Properly?
A heat pump that runs but doesn’t cool often has airflow or control issues. Common causes include a dirty filter, blocked outdoor coil, incorrect thermostat mode, iced-over coil, low refrigerant, or a failing reversing valve. Our NATE-certified techs can diagnose with advanced tools and provide a clear report of pressures, cleaning performed, adjustments made, and recommendations.
Quick checks:
- Set thermostat to Cool and fan Auto.
- Replace/clean filter.
- Clear debris from the outdoor unit.
