Why Is My Heat Pump Running But Not Cooling Properly?

Your heat pump may run but not cool due to airflow, thermostat, refrigerant, or mode issues. Common causes include a dirty filter or coil, a blocked outdoor unit, the thermostat set to heat, low refrigerant, a tripped air-handler breaker, ice on the coil, or an undersized system in extreme heat. In Bloomington and Martinsville, we provide 24/7 emergency service, precision tune-ups, and service plans with upfront pricing and a 1-year warranty on heating products and services.

Quick checks:

• Set thermostat to Cool and lower 3–5°F.
• Replace filter; clear debris around outdoor unit.
• Check breakers for the air handler.
• If iced, turn off and let it thaw. <br/>
