Why Is My Heat Pump Running But Not Cooling Properly?

A heat pump can run but not cool due to airflow problems, incorrect thermostat settings, blocked outdoor coils, low refrigerant, or duct issues. We provide timely heat pump repair, maintenance, and emergency replacement in Ellicott City and nearby. Twice-yearly maintenance (Buric Club from $20/month) helps prevent these issues.

Quick checks:

• Set thermostat to Cool and fan to Auto.
• Replace or clean air filters.
• Clear debris around the outdoor unit.
• Check the breaker and thermostat batteries.
• If you see ice or constant defrost, turn it off and call.
