Furnace Repair and Upton MA’s Trusted Heating & Cooling Professionals — Your Local Experts

SumZero Energy Systems delivers exceptional service with quality craftsmanship on every Furnace Repair. We begin with a precise diagnostic to find the root cause: checking thermostats and controls, testing safety switches and limit controls, inspecting the heat exchanger, cleaning burners and the flame sensor, verifying ignition and gas pressure, assessing airflow and static pressure, replacing clogged filters, and evaluating the blower motor and belts. This process quickly resolves common problems such as no heat, short cycling, uneven temperatures, strange noises, ignition or pilot issues, weak airflow, and rising energy bills. After repairs, we calibrate the system, test for carbon monoxide, and confirm efficient performance so your home warms up fast and stays safe. In addition to repair, we provide full-service heating and cooling solutions, including furnace and boiler installation and replacement, seasonal maintenance and tune-ups, emergency service, heat pump and AC repair, indoor air quality improvements, ductwork and sealing, and smart thermostat integration.
