If you live in Massachusetts and have heard about heat pump rebates but you’re not sure how they actually work, this guide walks through exactly what’s available in 2026, who qualifies, and how the numbers play out for a typical eastern Massachusetts home. The headline: up to $10,000 in rebates plus 0% financing, and the program covers most of the older oil-and-gas-heated homes in our service area.
What Mass Save Actually Is
Mass Save is the program brand for the energy-efficiency initiatives funded by Massachusetts gas and electric utilities — National Grid, Eversource, and a handful of municipal utilities. The rebates aren’t paid by Mass Save directly; they’re paid by the utility through the program. The reason the utilities do this is that the state of Massachusetts requires them to fund energy reduction programs as part of their regulated rate structure. The money comes from the energy efficiency charge on your gas and electric bill — so in a real sense, you’ve been paying into Mass Save for years whether you’ve claimed the rebates or not.
What Heat Pump Rebates Are Available in 2026
The big number — up to $10,000 — applies to whole-home heat pump installations that qualify under the Mass Save Whole-Home Heat Pump program. To get the full $10,000, you generally need to: (1) install heat pumps that handle 100% of your home’s heating load (not just supplemental cooling); (2) remove or disable your existing oil or propane heating system as part of the conversion; (3) work with a Mass Save registered heat pump installer; and (4) meet the program’s efficiency and equipment specifications. Partial installs and supplemental zones get smaller rebates — typically $1,250-$2,500 per zone, capped at a per-home limit.
Plus 0% Financing
On top of the rebates, the Mass Save HEAT Loan offers up to $50,000 in 0% financing for qualifying energy efficiency upgrades — including heat pumps, weatherization, and high-efficiency boilers and furnaces. The loan is administered through participating banks and credit unions, and the interest is paid by the Mass Save program. For most of our customers the math works out so the monthly loan payment is comparable to or less than what they were paying for oil heat — meaning the upgrade essentially pays for itself on day one.
Who Qualifies in Eastern Massachusetts
Most homeowners in our service area — Winchester, Arlington, Medford, Lexington, Cambridge, Belmont, Burlington, Newton, Woburn, Reading, Wakefield, and the surrounding towns — are eligible. Income-qualified programs are also available with enhanced rebates for households at or below 60% of state median income. Renters can sometimes participate with landlord cooperation. Multi-family buildings have their own rebate structure. The simplest first step is having a Mass Save registered installer (we are one) walk through your house and tell you what you qualify for.
What Heat Pump Equipment Qualifies
Cold-climate heat pumps from Mitsubishi, Fujitsu, Daikin, Carrier, and a handful of other manufacturers qualify for the highest rebate tier. The equipment has to meet HSPF and SEER efficiency thresholds. The installer has to be Mass Save registered. The system has to be sized correctly to the home (not the rule-of-thumb oversizing that some installers use). Done correctly, a modern cold-climate heat pump heats reliably down to -13°F outdoor temperature and provides cooling in summer.
How the Process Actually Works
From your perspective, the typical timeline runs about 4-8 weeks: free in-home assessment by a registered installer (1 day), heat load calculation and equipment proposal (1-2 weeks), Mass Save rebate pre-approval (1-2 weeks, runs in parallel with permitting), permits and gas/electrical service modifications (1-2 weeks), installation (2-5 days depending on scope), inspection, and final rebate submission (1-2 weeks after install). The installer handles every step of the rebate paperwork on your behalf.
What to Watch Out For
A few things to know before you start. First, not every contractor is Mass Save registered — and only registered installers can submit for the rebates. Second, sizing matters: an undersized system won’t keep up in a New England cold snap, and an oversized system short-cycles and wastes energy. Third, the rebate program changes year-over-year as the state’s climate goals advance. The 2026 program has more generous rebates than 2024 did, and the 2027 program likely will too. If you’re considering a heat pump conversion, the time to start the conversation is now — before the heating season.
