Why Is My Heat Pump Running But Not Cooling Properly?

Your heat pump can run but not cool due to airflow, refrigerant, or control issues. Common problems we service include dirty filters, low refrigerant, thermostat miscalibration, a blocked outdoor unit, or a failing reversing valve. Seasonal tune-ups twice a year help prevent weak airflow and short cycling. We offer diagnostics, repairs, and 24/7 emergency service in the La Porte area.

Quick checks:

• Set thermostat to Cool and 3°F below room temp.
• Replace or clean the air filter.
• Clear debris from the outdoor unit.
• Check vents are open and returns unblocked.
