Towne & Country Plumbing & Heating

The Town of Duxbury requires a building permit for HVAC system replacement through the Building Department, plus a separate electrical permit for new heat pump circuits. Standard permits typically clear in a few business days. Because much of Duxbury borders Duxbury Bay, the marshes, and conservation land, Conservation Commission review is common for work on properties near wetlands or the shoreline — worth confirming early. Historic homes near Powder Point and the old town center may face added scrutiny for street-visible exterior changes.

HVAC costs in Duxbury track the South Shore market, generally below Boston metro pricing but with a coastal premium. A like-for-like oil or propane boiler replacement is typically $7,500–$12,000 installed; a single-zone ductless mini-split runs $4,000–$7,500; a whole-home cold-climate heat pump retrofit is typically $18,000–$30,000 before rebates, with larger Duxbury homes often at the upper end. Bayside and near-shore properties may add a modest upcharge for corrosion-resistant outdoor coils to handle salt-air exposure.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential hvac work; ask for the registration number and check it before paying a deposit.
