AC Repair and Burlington MA’s Trusted Heating & Cooling Professionals — Your Local Experts

Once identified, our certified technicians perform precise repairs, replace worn parts, clean coils and drains, seal leaks, recharge refrigerant when appropriate, and complete a full performance test to ensure reliable, efficient cooling. Beyond repairs, SumZero Energy Systems offers complete HVAC services including new system installation and replacement, seasonal maintenance tune‑ups, ductless mini‑splits and heat pumps, furnace and boiler service, indoor air quality solutions, ductwork design and sealing, smart thermostat upgrades, and 24/7 emergency support.
