Reliable, High-Quality Furnace Repair to Restore Comfort—Fast

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

At SumZero Energy Systems, our "Furnace Repair" process starts with a precise diagnostic to find the root cause of issues like no heat, short cycling, uneven rooms, unusual noises or odors, weak airflow, or rising energy bills; we inspect thermostats and controls, test igniters and flame sensors, verify gas pressure and electrical connections, assess heat exchanger integrity, evaluate blower motors and capacitors, and check airflow and ductwork for restrictions and safety concerns. We then make targeted fixes—cleaning and calibrations, sealing, and quality replacements for worn parts (filters, igniters, sensors, motors)—followed by thorough performance and safety testing so your heat runs efficiently and reliably. Beyond repairs, we provide comprehensive services including seasonal maintenance and tune-ups, new system installation and replacement, heat pumps and AC repair, smart thermostats, indoor air quality solutions, and ductwork improvements. Expect exceptional service, clear communication, and quality craftsmanship from SumZero Energy Systems—proudly and professionally serving the Chelsea, MA area.
