Massachusetts Energy Rebates 2026: Mass Save, HOMES & HEAR Combined
Why Massachusetts Has an Edge on Everyone Else
Massachusetts has been running aggressive energy efficiency programs since the 1990s. Mass Save — the statewide initiative funded by a charge on utility bills — had rebate infrastructure in place years before HOMES and HEAR were written into law. When federal programs arrived, Massachusetts already had a trained contractor network, established application processes, and program administrators who knew how to manage rebate logistics.
That institutional depth shows in 2026. While some states are still figuring out how to disburse HEAR funds, Massachusetts has an operating rebate system that processes thousands of applications per year. The question for Massachusetts homeowners isn't whether rebates exist — it's how to maximize the stack.
Mass Save: The Foundation
Mass Save is administered by Massachusetts' electric and gas utilities: Eversource, National Grid, Unitil, Liberty Utilities, Cape Light Compact, and Columbia Gas. They pool resources under the Mass Save brand, though specific rebate amounts can vary by utility and service territory.
Core Mass Save rebates for 2026:
| Equipment | Standard Rebate | Income-Qualified Rebate |
|---|---|---|
| Cold Climate Heat Pump (ducted) | $1,500–$2,500 | Up to $10,000 |
| Mini-split (single zone) | $500–$1,500 | Up to $4,000 |
| Heat Pump Water Heater | $750 | $1,500 |
| Insulation (attic) | 75% of cost, up to $2,000 | 100% covered |
| Air sealing | 75% of cost | 100% covered |
| Smart thermostat | $75–$100 | $100 |
The cold climate heat pump rebate is one of the highest utility-funded rebates in the country. Massachusetts utilities prioritize heat pumps rated to operate efficiently below 0°F — brands like Mitsubishi Hyper-Heating, Daikin, and Bosch qualify based on efficiency ratings rather than brand name alone.
Mass Save No-Interest Financing
Beyond rebates, Mass Save offers 0% interest HEAT Loans for up to $25,000 to finance qualifying improvements. In a high-rate lending environment, a no-cost loan significantly changes the economics of large projects. A $20,000 heat pump installation that gets $5,000 in Mass Save rebates plus a 0% $15,000 loan looks very different from the same project financed at 8–10%.
HEAT Loans are available through participating lenders — find them at masssave.com. The loan term is typically 7 years, though project size affects terms.
Federal HEAR Program in Massachusetts
Massachusetts has fully implemented HEAR (High-Efficiency Electric Home Rebate Act) funding through Mass Save's administrative infrastructure. This means you apply for HEAR through Mass Save — the state chose to route federal dollars through the existing utility program rather than building a separate application system.
HEAR rebate amounts in Massachusetts (income-qualified only — at or below 150% AMI):
| Category | Max HEAR Rebate |
|---|---|
| Heat pump (space heating/cooling) | $8,000 |
| Heat pump water heater | $1,750 |
| Electric panel upgrade | $4,000 |
| Insulation and air sealing | $1,600 |
| Electric wiring | $2,500 |
| Electric stove or range | $840 |
| Electric dryer | $840 |
Households between 80% and 150% AMI get 50% of the HEAR maximum. Households at or below 80% AMI get 100%. Check current income limits for your county through Mass Save or the Massachusetts income qualification guide.
HOMES Program in Massachusetts
HOMES (Home Efficiency Rebates) are whole-home performance rebates tied to documented energy savings, not specific equipment. Massachusetts administers HOMES through the same Mass Save infrastructure as HEAR.
- 20–34% modeled energy savings: Up to $2,000 standard / $4,000 income-qualified
- 35%+ modeled energy savings: Up to $4,000 standard / $8,000 income-qualified
HOMES requires a certified energy auditor to model your home's energy use before and after improvements. In Massachusetts, Mass Save's Home Energy Assessment (the rebate program's entry point) doubles as the qualification audit for HOMES purposes. Schedule a free assessment at masssave.com — it's the first step for any major project.
Stacking Mass Save + HEAR + HOMES
The combination can be substantial. A Massachusetts homeowner at 80% AMI replacing a gas boiler with a cold climate heat pump and upgrading insulation:
| Program | Item | Amount |
|---|---|---|
| Mass Save | Cold climate heat pump | $10,000 |
| Mass Save | Insulation (100%) | $3,500 |
| HEAR | Heat pump | $8,000 |
| HEAR | Insulation | $1,600 |
| HOMES | 35%+ whole-home savings | $8,000 |
| Total | $31,100 |
The Mass Save and HEAR stacking rules require that combined rebates don't exceed total project cost — but for large projects, the ceiling rarely creates a practical limit. Use the heat pump rebate calculator to model your specific situation.
Contractor Requirements in Massachusetts
Mass Save rebates require using a participating contractor from their vetted network. You can find qualified contractors through masssave.com — entering your zip code returns a list of Mass Save-enrolled contractors for each equipment category. Working with a non-participating contractor means losing access to most Mass Save rebates, which is a significant financial hit.
HEAT Loan financing also requires a participating contractor. The contractor selection step matters more in Massachusetts than in states with more open program rules.
For heat pumps specifically, look for contractors with Mass Save certification in cold climate heat pump installations. This specialty certification indicates training on equipment performance in Massachusetts winters — relevant when sizing and selecting equipment for a climate that regularly sees temperatures in the single digits.
Low-Income Programs: Weatherization and Energy Assistance
Massachusetts operates several additional programs for households at or below 60% of state median income:
- Low-Income Weatherization Assistance Program (LIWAP): Free weatherization services including insulation, air sealing, and mechanical system upgrades. Administered through local community action agencies.
- Neighbor Energy Fund: Emergency heating assistance beyond LIHEAP for households in crisis
- First Call for Help (211): Coordinates referrals to energy assistance programs across the state
For very low-income households, LIWAP can provide comprehensive weatherization at no cost — covering improvements that would cost $5,000–$15,000 out of pocket. These households may then qualify for additional equipment rebates through Mass Save's income-qualified tiers layered on top of the weatherization work.
Solar in Massachusetts 2026
Massachusetts has its own state solar incentive — the Solar Massachusetts Renewable Target (SMART) program — which provides a fixed payment per kWh generated, administered by Eversource, National Grid, and Unitil. SMART pays a set rate for 10 years, creating predictable income from a solar array.
SMART payment rates depend on system size, utility territory, and available capacity in each "block" of the program. Rates have stepped down as each block fills — new applicants should check current available rates at masscec.com before finalizing solar economics. The 25C federal tax credit is gone, but SMART plus net metering continue to support solar economics in Massachusetts.
See Massachusetts full rebate listing for current SMART rates and solar incentives alongside heat pump and weatherization programs.
Timeline: How Long Does Mass Save Take?
Mass Save is well-run by utility program standards, but demand is high and timelines extend accordingly:
- Home Energy Assessment: 2–4 week wait for scheduling, depending on season (longer in fall/winter)
- Contractor installation: Varies by contractor availability — heat pump specialists often booked 6–8 weeks out in peak seasons
- Rebate processing: 6–8 weeks after installation and paperwork submission
- HEAT Loan approval: 1–2 weeks through participating lenders once application is complete
Start the process early. Homeowners who decide in spring tend to have installations complete before heating season. Those who decide in September often find contractors unavailable until spring.
What's Not Covered
Mass Save and HEAR don't cover everything. Solar panel installation (covered by SMART/net metering), battery storage (not currently rebated through Mass Save), and EV charger installations are outside the primary Mass Save rebate structure. Some utilities offer EV charger rebates separately — check with your utility's EV programs.
For panel upgrades required specifically to support a heat pump or EV charger, HEAR covers up to $4,000 — but general panel upgrades not directly tied to an electrification project may not qualify. Document the connection between your panel upgrade and the qualifying appliance when applying.
