Brennan & Co.

Edgartown requires a Building Department permit for HVAC system replacement and a separate electrical permit for heat-pump circuits. The Edgartown Historic District Commission tightly controls exterior changes across the village historic district — outdoor heat-pump placement visible from public streets needs Commission sign-off, and creative siting (rear elevations, screened enclosures) is the norm. Conservation Commission review applies on coastal-bank, salt-pond, and wetland-buffer parcels, which covers a large share of waterfront and pond-adjacent lots.

HVAC costs in Edgartown run at the high end of the Vineyard market — ferry logistics for materials, a small island labor pool, and salt-air rated equipment as standard spec all add up. A whole-home cold-climate heat pump install typically runs $26,000–$42,000 before rebates; a single-zone ductless mini-split installs for roughly $5,500–$10,000; a like-for-like oil boiler replacement usually lands around $9,500–$15,000. Off-season scheduling can save real money versus peak-summer install windows.

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.
