Reliable, high‑quality Furnace Maintenance that solves problems fast and restores comfort

Furnace Maintenance and Maynard MA’s Trusted Heating & Cooling Professionals — Your Local Experts

During a scheduled Furnace Maintenance visit, SumZero Energy Systems technicians perform a thorough inspection, deep cleaning, and precision tune-up to keep your system safe, efficient, and reliable. We calibrate thermostats, replace or clean filters, test ignition systems and flame sensors, verify gas pressure and combustion, inspect heat exchanger integrity, tighten electrical connections, lubricate moving parts, clear condensate lines, assess blower motor performance, and confirm proper venting and carbon monoxide safety. This proactive care identifies and resolves common problems—dirty filters, uneven heating, short cycling, ignition or pilot failures, noisy operation, airflow restrictions, thermostat inaccuracies, rising energy costs, and surprise breakdowns—before they disrupt your home. Beyond maintenance, we offer fast repairs, emergency service, new system design and installation, furnace and boiler replacements, heat pumps, central AC and ductless mini-splits, ductwork repair and sealing, zoning and smart thermostats, and indoor air quality solutions. Expect exceptional service, quality craftsmanship, clear communication, and honest recommendations from the team you trust at SumZero Energy Systems. We are proudly and professionally serving the Maynard, MA area.
