Falmouth Energy

Falmouth requires a building permit for HVAC system replacement, processed through the town Building Department, with a separate electrical permit through the Wiring Inspector. Heat pump installs near the coast or on lots with wetlands frontage may also need Conservation Commission review for outdoor unit placement — Falmouth has extensive coastal resource areas, salt marshes, and freshwater ponds with regulated buffers. Standard permits typically issue within a week or two; coastal reviews can add three to six weeks depending on the season and the specific site.

Falmouth pricing runs slightly higher than mid-state averages because of the salt-air equipment upgrades and the seasonal labor squeeze. A whole-home cold-climate heat pump retrofit typically runs $22,000–$34,000 before rebates, single-zone ductless mini-splits land in the $5,000–$8,500 range, and a like-for-like gas or propane boiler swap is $8,000–$13,000. Coastal-grade coil and cabinet options add roughly $500–$1,500 per outdoor unit but materially extend equipment life in direct 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.
