Heat Pump Repair and Wellesley MA’s Trusted Heating & Cooling Professionals — Your Local Experts

Our Heat Pump Repair starts with a thorough diagnostic to pinpoint issues quickly and accurately—we check refrigerant pressures, electrical components, airflow and ductwork, coil condition, thermostat calibration, and the defrost and reversing valve operation. Typical problems we resolve include no heat or cooling, short cycling, uneven temperatures, frozen or noisy outdoor units, refrigerant leaks, tripped breakers, failed capacitors or contactors, blower or fan motor failures, clogged drains, and sensor or thermostat faults. After identifying the cause, we make precise repairs, replace worn parts, clean and recalibrate components, and optimize system settings to restore comfort and efficiency fast.
