Heating & Cooling in Cambridge, MA

Old housing, new comfort, properly done. Get your free Cambridge estimate.

Cambridge houses more building types per square mile than anywhere in New England: triple-deckers in Cambridgeport, mansard Victorians off Mass Ave, workers' cottages in North Cambridge, and condo conversions of all of the above. What most share: age, character, and mechanical systems from another century. Our Cambridge work is dominated by heat pump retrofits (mini-splits threading through triple-decker floors, compact ducted systems hidden in condo renovations) because that's what these buildings and this city's climate goals both call for.

Condo owners and small landlords: we're fluent in the realities of association approvals, line-set routing that keeps facades clean, and per-unit metering. Qualifying heat pump installations may be eligible for Mass Save® rebates up to $16,000, and income-eligible customers may qualify for no-cost energy efficiency services (MassSave.com/IncomeEligible). Our crews cover Cambridge regularly; centuries-old housing is our home turf, even here.
