Reliable, High-Quality Furnace Maintenance to Solve Issues Fast and Restore Your Comfort

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

During Furnace Maintenance, our certified technicians perform a comprehensive multi-point inspection and tune-up to keep your system safe, efficient, and dependable—cleaning burners and flame sensors, replacing filters, tightening electrical connections, lubricating motors, testing ignition and safety controls, checking thermostat calibration, measuring gas pressure and airflow, and verifying heat exchanger integrity and carbon monoxide safety. This proactive approach identifies and resolves common issues such as uneven heating, short cycling, strange noises, reduced airflow, rising energy bills, and no-heat situations before they turn into costly breakdowns. Beyond maintenance, we deliver complete HVAC care: precise diagnostics and repairs, high-efficiency system replacements and new installations (furnaces, boilers, heat pumps, ductless mini-splits), ductwork design, repair, and sealing, indoor air quality solutions (humidifiers, dehumidifiers, air cleaners), and smart thermostat upgrades. Customers trust SumZero Energy Systems for exceptional service and quality craftsmanship, delivered with clear communication and a friendly, professional touch. SumZero Energy Systems proudly and professionally serves the Watertown, MA area.
