Whether you're looking to ditch your oil furnace, upgrade from inefficient electric baseboard heat, or simply want a more efficient way to heat and cool your home, this guide covers everything you need to know about Massachusetts heat pump rebates.
How Much Is the Heat Pump Rebate in Massachusetts?
Massachusetts heat pump rebate amounts depend on two main factors: your current heating fuel and whether you qualify as income-eligible. Here's the breakdown:
2026 Mass Save Heat Pump Rebates
| Current Fuel | Standard Rebate | Income-Qualified | Notes |
|---|---|---|---|
| Oil or Propane | $2,650/ton, up to $8,500 | Up to $16,000 | Whole-home rate. Eligible for the income-based enhanced tier |
| Electric Resistance | $2,650/ton, up to $8,500 | Up to $16,000 | Baseboard or electric furnace. Eligible for the enhanced tier |
| Natural Gas | $2,650/ton, up to $8,500 | Not eligible | Standard rebates apply, but gas customers cannot claim the enhanced tier |
| Heat Pump Water Heater | $750, or $1,500 split-system | No cost via CAP agencies | Can combine with whole-home rebates |
Why Oil & Propane Get Higher Rebates
Massachusetts prioritizes reducing carbon emissions. Since oil and propane heating produces more emissions than natural gas, the state offers larger incentives to switch these households to efficient electric heat pumps.
Who Qualifies for Heat Pump Rebates?
To qualify for a Massachusetts heat pump rebate, you must meet these requirements:
- Massachusetts resident with an active utility account (Eversource, National Grid, Unitil, Cape Light Compact, or municipal utility)
- Own or rent your home (renters need landlord approval)
- Use a Mass Save partner contractor for installation
- Equipment meets efficiency requirements (your contractor will verify)
Income-Qualified Enhanced Rebates
Households with income at or below 80% of the Area Median Income (AMI) qualify for enhanced rebates. At 60% AMI or below, you may qualify for 100% of installation costs covered. Check eligibility at Mass Save's website or call your utility.
Types of Heat Pumps That Qualify
Massachusetts rebates cover several types of heat pumps. The best choice depends on your home's existing ductwork and heating needs.
Ductless Mini-Splits
Individual wall-mounted units that heat and cool specific rooms. Ideal for homes without existing ductwork.
- • No ductwork required
- • Zone-by-zone temperature control
- • Lower installation cost
- • Great for additions or targeted comfort
Ducted Air Source Heat Pumps
Central systems that use your existing ductwork. Best whole-home solution for houses with ducts.
- • Uses existing ductwork
- • Whole-home heating & cooling
- • Replaces central AC + furnace
- • Highest efficiency models available
Heat Pump Water Heaters
Use heat pump technology to heat water 2-3x more efficiently than traditional electric water heaters.
- • 2-3x more efficient than electric
- • $750, or $1,500 for a split system
- • Can combine with whole-home rebates
- • 10+ year lifespan
Ground Source (Geothermal)
Most efficient option, using stable underground temperatures. Higher upfront cost but lowest operating costs.
- • Highest efficiency (400-600% COP)
- • Separate incentive programs
- • 25+ year lifespan
- • Best for new construction
How to Apply for Massachusetts Heat Pump Rebates
Schedule a Home Energy Assessment
Start with a free Mass Save Home Energy Assessment. An energy specialist will evaluate your home, recommend improvements, and explain available rebates. This step is required for most rebates.
Get Quotes from Mass Save Partner Contractors
You must use a participating contractor to qualify for rebates. Mass Save provides a searchable directory, or your energy assessment specialist can provide recommendations.
Review & Sign Your Contract
Your contractor will prepare a quote showing the rebate amount. Many contractors offer "instant rebates" where they deduct the rebate from your invoice upfront.
Installation & Inspection
Your contractor installs the heat pump system. Some installations may require a post-installation inspection to verify proper setup and qualify for the rebate.
Receive Your Rebate
If you didn't receive an instant rebate, your contractor submits the paperwork and you'll receive a check within 4-8 weeks. Keep all documentation for your records.
The Federal Credit That Ended
Through 2025, Massachusetts residents had a second lever: you could combine a Mass Save heat pump rebate with the federal Energy Efficient Home Improvement Credit (25C) for up to $2,000 more. The One Big Beautiful Bill Act (P.L. 119-21) repealed 25C effective 31 December 2025, so for 2026 work the Mass Save rebate stands alone.
Real Example: Oil-to-Heat-Pump Conversion
* The federal 25C credit used to take a further $2,000 off this. It was repealed effective 31 December 2025. The remaining balance can go on the Mass Save HEAT Loan at 0% interest.
Don't Forget 0% Financing
Mass Save also offers 0% interest loans (HEAT Loan) up to $25,000 with terms up to 7 years. This can cover your remaining costs after rebates, making the upgrade virtually free upfront.
Timeline: What to Expect
The full process from inquiry to installation typically takes 4-8 weeks, depending on contractor availability and project complexity.

The Bottom Line
Massachusetts offers some of the best heat pump rebates in the country. With up to $16,000 available through Mass Save on the income-Enhanced tier, many homeowners still cut their installation costs by half or more — even without the $2,000 federal credit, which was repealed effective 31 December 2025.
The key is starting with a Home Energy Assessment and working with Mass Save partner contractors. This ensures you qualify for the maximum rebates and get proper installation.
For income-qualified households, heat pumps can be essentially free. Even at full price, the combination of Mass Save rebates and the 0% HEAT Loan still makes 2026 a reasonable time to switch — though the federal credit that used to sweeten it ended on 31 December 2025.
