New Hampshire
Where We Work in New Hampshire
Somersworth is home base, so Strafford County gets our fastest response times — most NH towns below are 10 to 25 minutes out. Click your town for details on the heating and cooling work we do there.
Maine
Where We Work in Southern Maine
Somersworth sits right on the Maine border — Berwick is literally across the bridge. The state line doesn’t change the work: same equipment, same 24/7 emergency coverage, and we’re happy to point Maine homeowners toward Efficiency Maine heat pump rebates.
