Why Is My Heat Pump Running But Not Cooling Properly?
If your heat pump runs but isn’t cooling, likely causes are incorrect thermostat mode, a dirty filter or coil, blocked outdoor unit airflow, low refrigerant, or a ductless zone set to fan/heat. Our NATE-certified technicians can diagnose, repair, and recommission all major brands. We serve Denver, Englewood, and the surrounding metro area.
Quick checks:
- Set thermostat to Cool and lower the setpoint.
- Replace or clean the air filter.
- Clear debris around the outdoor unit.
- For mini-splits, confirm each room remote is set to Cool.
