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

When your heat pump struggles, SumZero Energy Systems responds quickly with a precise, step‑by‑step diagnostic to find the root cause and fix it right the first time. We check refrigerant pressure, airflow and static pressure, electrical components, thermostat calibration, sensors, coils, drains, the defrost cycle, and the reversing valve and compressor. Then we make targeted repairs—replacing failed capacitors, contactors, fan motors, or sensors; repairing leaks and restoring charge; clearing drains and thawing frozen coils; cleaning coils and filters; correcting wiring and control issues; and recalibrating thermostats—so your system runs reliably again. Common problems we solve include no heat or cooling, uneven temperatures, weak airflow, short cycling, unusual noises, icing or frozen coils, rising energy bills, and error codes. Beyond Heat Pump Repair, we offer complete HVAC solutions: new system installation and replacement, seasonal tune-ups and maintenance plans, emergency service, ductless mini-splits, furnaces and central AC, indoor air quality upgrades, smart thermostats, and ductwork repair and sealing.
