Massachusetts offers substantial rebates for water heater and HVAC upgrades in 2025, helping homeowners save thousands while improving efficiency.

Massachusetts homeowners can receive a $750 instant rebate on qualifying heat pump water heaters through the Mass Save program for 2025. This isn’t a mail-in rebate you wait months to receive. Contractors can provide the $750 instant incentive through participating distributors, or customers can purchase directly from Home Depot or Lowe’s to receive the instant rebate.
Heat pump water heaters are up to three times more efficient than conventional electric water heaters, which means the savings continue long after installation. Operating costs can be up to 50% lower than electric, oil, or propane water heaters. When you factor in the rebate plus ongoing energy savings, the math becomes compelling fast.
Not every water heater qualifies for Massachusetts rebates. The equipment must be installed by a licensed plumber between January 1, 2025 and December 31, 2025, be ENERGY STAR certified, and be new equipment replacing an existing electric resistance, propane, natural gas, or oil water heater.
The equipment must be installed in a residential home with 1-4 units, and offers are valid only for residential customers where Berkshire Gas, Cape Light Compact, Eversource, Liberty Utilities, National Grid, or Unitil is the Program Sponsor. Most Massachusetts homeowners fall under one of these utility companies, but it’s worth verifying before you commit to a purchase.
The key detail many homeowners miss is the licensed plumber requirement. You can’t install this yourself and expect the rebate. The good news is that working with a qualified contractor often means they handle the rebate paperwork for you, turning what could be a bureaucratic headache into a seamless process.
While heat pump water heaters cost more upfront than conventional units, they’re 3 to 4 times more efficient, meaning the electricity savings pay for the added cost within a few years. Factor in the $750 rebate, and you’re looking at a system that practically pays for itself while delivering superior performance.
Mass Save sponsors offer 0% financing HEAT Loans up to $25,000 for qualified home improvements, making energy efficiency upgrades more affordable for Massachusetts residents. This isn’t your typical home improvement loan with interest eating into your savings.
The HEAT Loan program offers up to $25,000 towards the purchase and installation of qualifying systems with no interest, maximizing your savings potential. Loan terms are income-dependent, with qualified homeowners accessing 7-year terms for those earning 81-135% of State Median Income.
The beauty of this program is that it removes the upfront cost barrier that stops many homeowners from upgrading. Instead of draining your savings account for a water heater replacement, you can spread the cost over several years while immediately benefiting from lower energy bills. Rebates are based on the installation date, so timing your project within the program year is crucial.
What makes this particularly attractive is that you’re essentially borrowing money at 0% to install equipment that immediately starts saving you money on utilities. The monthly loan payment is often less than the monthly energy savings, meaning you’re cash-flow positive from day one while building equity in a more efficient home.
Massachusetts homeowners can save up to $16,000 with 2025 Mass Save heat pump rebates, with $10,000 available for whole-home systems. These aren’t small rebates that barely make a dent in your project cost. We’re talking about substantial money that can transform an expensive upgrade into an affordable investment.
Equipment must be installed between January 1, 2025 and December 31, 2025 by a contractor participating in the Mass Save Heat Pump Installer Network, be ENERGY STAR Cold Climate certified, and replace oil, propane, natural gas, or electric baseboard as the primary heating system. The whole-home rebate requires meeting specific weatherization requirements, but partial-home rebates are available for systems that don’t qualify for the full amount.
The $10,000 whole-home rebate requires meeting specific weatherization requirements, hiring a qualified contractor, and installing a qualified air-source heat pump to heat and cool your entire home, with your existing heating system fully disabled or removed. This is an important change from 2023, when you were allowed to keep your old heating system for emergency use.
Your home has sufficient weatherization if it was built in 2000 or later, if a free Mass Save home energy assessment finds you need less than $1,000 worth of recommended upgrades, or if upgrades recommended during a home energy assessment in 2012 or later have been performed. This isn’t as restrictive as it sounds—many homes naturally qualify, and the required upgrades are often minimal.
For homes that don’t meet the whole-home requirements, partial rebates are still substantial. Partial rebates are set at $1,250 per ton up to $10,000 for systems that keep fossil fuel backup integrated with heat pump controls. Even if you don’t qualify for the maximum rebate, you’re still looking at thousands in savings.
Systems meeting specific efficiency requirements also qualify for Federal 25C Energy Efficient Home Improvement Credits equal to 30% of the heat pump install cost after the Mass Save rebate is applied, up to $2,000 annually, with an additional $600 credit available for electrical panel upgrades. Stack these incentives together, and the savings become truly significant.
Utility companies provide these rebates due to limitations on how much supply they can generate—new power plants and natural gas supply systems are extremely expensive and take years to build, so reducing demand while ensuring comfortable homes helps avoid raising rates or fees for new infrastructure.
HVAC systems are among the largest users of power and fuel in homes, and new systems can reduce bills by 30%, which combined with rebates allows systems to pay for themselves in a relatively short period. There are also environmental benefits to reductions in energy production and consumption.
This creates a win-win situation. You get substantial upfront savings and ongoing energy cost reductions, while utilities avoid massive infrastructure investments. The main goal is installing equipment that uses less energy while maintaining your desired comfort level.
Understanding this dynamic helps you see why these rebate programs are so well-funded and likely to continue. It’s not charity—it’s smart business that benefits everyone involved. When planning a new system, ask your installer and utility provider about available rebate programs, as your HVAC company should be able to facilitate processing and maximize your savings.
The timing aspect is crucial here. These programs have annual funding limits and specific installation deadlines. Projects must be installed by December 31st to qualify for current-year rebates. Planning ahead ensures you don’t miss out on thousands in available incentives.
Massachusetts has created an unprecedented opportunity for homeowners to upgrade their water heaters and HVAC systems at a fraction of normal cost. Between Mass Save rebates, federal tax credits, and 0% financing options, the barriers that traditionally prevented these upgrades have largely disappeared.
The key is acting within the program timelines and working with qualified contractors who understand the rebate landscape. Working with experienced contractors ensures you receive rebates instantly, eliminates paperwork hassles and wait times, and helps navigate the complex application process to receive maximum rebates for your upgrades.
Don’t let another heating season pass with an inefficient system that’s costing you money every month. We at Dempsey Energy have helped Massachusetts homeowners navigate these rebate programs for years, ensuring you capture every available dollar while getting the reliable, efficient systems your home deserves.
