Heating Installation & Repair in Sudbury, MA

Heating Installation & Repair in Sudbury, Massachusetts

Sudbury residents trust Mass HVAC for professional heating installation & repair. Serving Middlesex County and the surrounding communities, we bring decades of combined experience to every heating, cooling, and air quality project.

Sudbury homeowners know that a reliable heating system is non-negotiable during Massachusetts winters. MetroWest experiences the full range of New England weather, with winter temperatures regularly dropping below 10°F and summer humidity pushing heat indices above 100°F. When your furnace or boiler fails, you need a contractor who responds fast, diagnoses accurately, and fixes it right the first time.

Mass HVAC provides comprehensive heating services in Sudbury and throughout Middlesex County:

• Emergency repair — our technicians carry common parts on every truck for same-visit repairs
• System replacement — we properly size every installation using industry-standard calculations
• Fuel conversions — oil to gas, oil to heat pump, or propane upgrades
• Preventive maintenance — catch cracked heat exchangers, worn ignitors, and other issues before they leave you without heat
• Zone control — solve the "hot downstairs, cold upstairs" problem with dampers and multiple thermostats

Many MetroWest homes still rely on aging oil furnaces or steam boilers from the 1980s and 1990s. With natural gas now available on most streets, oil-to-gas conversions are one of our most requested services in this area. For homes without gas access, cold-climate heat pumps provide an excellent all-electric alternative that qualifies for generous Mass Save rebates.
