Why Is My Heat Pump Running But Not Cooling Properly?

Your heat pump can run without cooling due to restricted airflow, thermostat issues, or a refrigerant or electrical problem. Dirty filters, debris at the outdoor unit, or short-cycling also reduce cooling. Our Chesterton technicians diagnose airflow, tighten electrical connections, check refrigerant, and calibrate thermostats. We service air-source and mini-split systems and offer 24/7 emergency repairs. If the system is 10–15 years old with rising energy bills, replacement may be the better investment.

Quick checks:

• Replace or clean the filter.
• Clear debris from the outdoor unit.
• Confirm the thermostat is set to cool.
