Rebates
Massachusetts homeowners can receive up to $8,500 in MassSave rebates for qualifying whole-home heat pump installations in 2026, plus 0% financing through the HEAT Loan program. Rebates require an HPIN-enrolled contractor and a system using next-generation refrigerants. Boston Climate Co. connects you with enrolled professionals who manage the entire process.
MassSave is an energy-efficiency program funded by Massachusetts utility providers that offers homeowners substantial financial incentives to upgrade to cleaner, more efficient heating and cooling systems. Heat pumps are the program's centerpiece because they replace fossil-fuel heating while providing efficient cooling in summer — a single system for year-round comfort. For Greater Boston homeowners facing some of the country's highest energy costs, these rebates can transform an expensive upgrade into one of the smartest investments you can make in your home.
The headline number is up to $8,500 for a qualifying whole-home heat pump installation. Whole-home rebates are calculated at roughly $2,650 per ton of heating capacity, capped at $8,500. If you're only converting part of your home, partial-home rebates are available at a lower per-ton rate. Income-eligible households may qualify for enhanced rebates that push total savings even higher. Stacked with the 0% HEAT Loan, the out-of-pocket cost of going electric drops dramatically for most Greater Boston homes. See real numbers in our HVAC Costs in Boston guide.
To qualify, your installation generally needs to meet a few conditions: the system must be an eligible high-efficiency heat pump, it must be installed by a contractor enrolled in the Heat Pump Installer Network (HPIN), and as of 2026 it must use a next-generation refrigerant. Some homes are also required to complete weatherization — insulation and air sealing — before or alongside the heat pump installation, since MassSave wants the home to actually hold the comfort the new system delivers. A licensed specialist can confirm exactly what your specific home needs.
The most important 2026 change is the refrigerant requirement. Systems must now use next-generation refrigerants such as R-32 or R-454B — older R-410A systems are no longer eligible for rebates. This reflects a national transition to lower-impact refrigerants. The practical takeaway for Boston homeowners: make sure any system you're quoted is rebate-eligible under the current rules, because installing the wrong equipment could cost you thousands in lost incentives.
The MassSave HEAT Loan offers qualified Massachusetts homeowners 0% interest financing for energy-efficiency upgrades, including heat pumps, with loan terms that make monthly payments manageable. Because it carries no interest, the HEAT Loan lets you spread the remaining cost — after rebates — across several years without paying a premium to finance. For many Greater Boston homeowners, the combination of an up-front rebate and 0% financing means upgrading to a modern heat pump costs far less per month than they expected.
Yes. Rebates require an installer enrolled in the Heat Pump Installer Network (HPIN). This is a meaningful safeguard for you as a homeowner — HPIN contractors are vetted to meet program standards, and they handle the rebate paperwork on your behalf so you're not navigating utility forms alone. Boston Climate Co. connects you exclusively with licensed, HPIN-enrolled professionals across Greater Boston, so your rebate eligibility is protected from the first conversation.
The cleanest path is to start with an HPIN-enrolled contractor who manages the process end to end: assessing your home, recommending an eligible system, completing the installation to program standards, and submitting the rebate application. Rather than researching forms and deadlines yourself, you let a qualified specialist do what they do every day.
