Why Is My Heat Pump Running But Not Cooling Properly?

If your heat pump runs but isn’t cooling, likely causes include a dirty outdoor coil, a clogged air filter, low refrigerant from a leak, or a stuck reversing valve. Thermostat miscalibration or loose electrical connections can also cut cooling performance. We service Indianapolis, Whitestown, and nearby areas, and provide 24/7 emergency repairs.

Quick checks:

• Set thermostat to Cool and lower the setpoint.
• Replace/clean the air filter.
• Clear debris from the outdoor unit and coil.
