Heating & Cooling in Lunenburg, MA

From the lake to the town line, comfort that keeps up. Get your free Lunenburg estimate.

Between Lake Shirley, Lake Whalom, and Massapoag Pond, a surprising amount of Lunenburg lives at the waterline, and lake houses are their own HVAC species. Many started as three-season camps and were winterized in stages, leaving a mix of electric baseboard, propane heaters, and hope. Mini-split heat pumps are the clean solution: efficient heat that ends the baseboard bills, real cooling for humid lake summers, all without ductwork the house never had.

Away from the water, Lunenburg's farmhouses and family colonials get the full menu: furnace and boiler replacements, central AC, heat pump conversions, water heaters. Every quote starts with a load calculation and ends with honest numbers, including whatever Mass Save® incentives your project may be eligible for (rebates up to $16,000 on qualifying heat pump installs). Some restrictions apply; we sort the details so you don't have to.
