Why Is My Heat Pump Running But Not Cooling Properly?

A heat pump that runs but does not cool usually has one of four issues: incorrect thermostat settings, restricted airflow, a dirty or blocked outdoor unit, or a refrigerant problem. Summers Plumbing Heating & Cooling installs, maintains, and repairs heat pumps, including 24/7 emergency service in the Fort Wayne area.

Quick checks:

• Set thermostat to Cool and lower the setpoint 3–5 degrees.
• Replace or clean the air filter.
• Clear debris from the outdoor unit and ensure 2–3 feet of space.
• Look for ice on the lines; turn system off if frozen and call a tech.
