Reliable, High-Quality Heat Pump Repair to Restore Comfort Fast

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

Heat Pump Repair starts with a thorough diagnostic designed to solve your issue quickly and correctly: we listen to your concerns, perform a multi-point inspection of electrical components, controls, airflow, and refrigerant circuits, verify charge and temperatures, test capacitors, contactors, and sensors, check the defrost cycle and reversing valve, and inspect coils, blower motors, and thermostats. Typical problems we resolve include no heat or cooling, short cycling, weak airflow, iced coils, unusual noises, refrigerant leaks, clogged condensate drains, thermostat misreads, and rising energy bills. Once we pinpoint the fault, we complete precise repairs—sealing leaks and recharging to spec, replacing worn parts, cleaning coils, clearing drains, recalibrating controls, optimizing airflow—and confirm performance before we leave. Beyond repairs, SumZero Energy Systems provides full-service HVAC solutions, including new heat pump and ductless installations, system replacements, seasonal maintenance and tune-ups, ductwork repair and sealing, indoor air quality upgrades, and smart thermostat integration. Count on our exceptional service, clear communication, and quality craftsmanship every time. SumZero Energy Systems is proudly and professionally serving the Westford, MA area.
