Mass Save Heat Pumps in Cambridge, MA

Think of it as a Mass Save program loan with zero interest, as much as up to $25,000, issued by member lenders such as local banks and credit unions. The package a lender reviews includes your utility account details, a project proposal from us and a signed program authorization; after the install, an inspector signs off. We help you put that package together; the lender makes the call.

That varies with the home and the equipment. One mini-split in a bedroom is quick work compared with converting an entire house and hauling out a boiler. Your written proposal spells out the schedule, and any rebate or loan steps that need to happen first are built into it.

Yes. A heat pump simply runs in reverse in warm weather, moving heat out of the house and pulling moisture from the air as it goes. Most of our customers retire their window units the first summer.

Air-source systems built for cold climates that appear on the Mass Save qualified product list, with matching indoor and outdoor units. We confirm the exact pairing on that list before you see a proposal, so the rebate is not left to chance.

Usually it does, because electricity is now doing the heating, while your oil purchases stop entirely. Your overall energy spending hinges on fuel prices, your house and how airtight it is. We will walk through what changes on each bill rather than promise a number.

Possibly, if a few conditions line up. The home needs a Home Energy Assessment and the insulation and air sealing it recommends, the system must use qualifying cold-climate equipment, and someone has to live there through the winter. We go through each condition with you on the first call.

In the 2026 program year, a qualifying whole-house system can earn up to $8,500, figured on each ton of capacity. Conditions apply: the home must be weatherized as its assessment directs, the equipment must qualify and the house must be occupied all winter. Partial-home setups qualify too, at a lower figure.

Room by room. We measure each space, note the windows, the insulation and the drafty spots, and calculate how much heat the house loses on a cold night. The old boiler's size is not a guide, since many were oversized from the start.

Very little. Wash or replace the filters in the indoor units regularly, keep the outdoor unit free of snow and leaves, and schedule a yearly check of the coils and drain lines. We show you all of it at the walkthrough.

They work very well there. Each apartment gets its own zone and controls, and we plan the outdoor units and how each unit is metered. Owners of two- to four-family homes, including landlords, use these programs too.
