Air Duct Repair and Dover MA’s Trusted Heating & Cooling Professionals — Your Local Experts

At SumZero Energy Systems, our Air Duct Repair starts with precision diagnostics—pressure and airflow testing, smoke tracing, and camera inspections—to pinpoint leaks, disconnected or crushed runs, damaged insulation, debris buildup, pest intrusion, whistling ducts, hot and cold spots, and rising energy bills; we then seal with mastic and UL‑181 tape, replace failing sections, re‑hang and brace ductwork, re‑insulate, repair boots and plenums, sanitize where appropriate, and balance airflow with final verification testing to ensure efficient, even comfort throughout your home. Beyond duct repairs, we offer comprehensive HVAC services, including furnace and AC repair, heat pump and mini‑split installation, indoor air quality solutions (advanced filtration, humidifiers, and smart thermostats), preventive maintenance, and full duct replacement and redesign when needed. You can count on our “exceptional service,” “quality craftsmanship,” transparent communication, and prompt scheduling from first call to final walkthrough—proudly and professionally serving the Dover, MA area.
