Why Is My Heat Pump Running But Not Heating Properly?
Your heat pump can run without heating due to low refrigerant, a dirty filter, frozen coils outside, or a faulty reversing valve. Thermostat issues, blocked outdoor airflow, or compressor problems can also reduce cooling. Shut the system off if you see ice on the outdoor unit to prevent damage. AirCo repairs leaks, recharges refrigerant, unclogs drains, and replaces failed parts such as sensors and other components for all brands. We offer 24/7 emergency repair and same-day options in Dallas and Fort Worth.
- Replace the air filter.
- Set the thermostat to Heat and Auto.
- Clear debris from around the outdoor unit.
