Grafton, MA Contractors: HVAC, Roofing, Plumbing & More

Grafton is a Worcester County town of about 19,650, home to the Tufts Cummings veterinary school and a classic New England common, with MBTA commuter rail service drawing Boston-bound residents. The town blends a historic center, older mill villages like Saundersville and Fisherville, and a growing number of suburban subdivisions and larger-lot homes.

The older village and center homes typically run gas or oil boilers with radiators and no central air, where ductless mini-splits are the natural upgrade. Newer subdivision homes often have forced-air ductwork that a ducted heat pump can reuse. With commuter-rail growth bringing newer households, full and partial heat pump retrofits are increasingly common across the town's varied housing.

Grafton is served by National Grid, an investor-owned utility, so homeowners qualify for the full Mass Save rebate program. Whole-home heat pump installs have recently qualified for up to $8,500 ($2,650 per ton) back after the required home energy assessment, with partial heat pump and mini-split systems generally in the $2,500–$6,000 range. The free Mass Save Home Energy Assessment is the usual first step — it unlocks the larger rebates and often turns up insulation and air-sealing work subsidized at 75% or more, which is valuable in older mill-village homes. Where forced-air ductwork already exists, a ducted heat pump can replace the furnace and AC in one project. The 0% HEAT Loan, up to $25,000, finances the conversion interest-free over seven years.

Grafton requires a building permit for any HVAC system replacement, filed with the town Building Department. Heat pump retrofits need a separate electrical permit for the dedicated circuits and outdoor disconnect. Permits are usually reviewed within a few business days, and reputable contractors handle the filings and inspections as part of the job. Subdivision homes with existing forced-air systems and adequate electrical capacity tend to permit and install quickly compared with older village homes that need new circuits.
