Current status: Mass Save rebates are available
Checked August 12, 2026. Mass Save publishes four air-source heat pump incentive paths for 2026. The right path depends on whether the new heat pump becomes the home’s only heating and cooling system, supplements an existing system, replaces an existing heat pump or air conditioner, and whether the household qualifies for enhanced support.
The federal Energy Efficient Home Improvement Credit under Section 25C ended for property placed in service after December 31, 2025. Do not include the former federal credit in a 2026 project budget.
2026 Mass Save amounts
| Rebate path | Published amount | When it fits |
|---|---|---|
| Whole-home | $2,650 per ton, up to $8,500 | The heat pump becomes the sole heating and cooling source and the project meets whole-home requirements |
| Partial-home | $1,125 per ton, up to $8,500 | A boiler or furnace remains available to supplement the heat pump |
| Basic | $250 per ton, up to $2,500 | Replacing an existing heat pump or central AC, conditioning a new space, or another project that does not displace fossil-fuel or resistance heat |
| Income-based enhanced | Up to $16,000 or up to no cost through Turnkey Services | Income-qualified households that meet the applicable program and existing-fuel requirements |
Mass Save calculates tons from the AHRI-rated cooling capacity divided by 12,000 BTU. A nominal model name is not enough: use the AHRI certificate for the exact indoor-outdoor equipment combination.
Partial-home projects may also qualify for a $500 weatherization bonus and a $500 sizing bonus under the conditions published by Mass Save. These are not automatic additions to every installation.
Check these gates before signing a contract
- Confirm the electric or gas utility. Mass Save is sponsored by participating investor-owned utilities and Cape Light Compact. Homes served by a municipal light plant may follow a separate local program instead.
- Complete the required Home Energy Assessment or other prerequisite before installation. The sequence matters for some rebate paths and bonuses.
- Use the current qualified equipment list and a participating contractor. Match the exact AHRI system, not only the outdoor unit’s brand and nominal capacity.
- Decide whole-home versus partial-home in writing. Leaving a boiler or furnace connected can change the rebate category even if the heat pump carries most of the annual load.
- Get the expected rebate on the proposal. The per-ton formula and $8,500 cap can produce a different result from a contractor’s initial verbal estimate.
Worked examples
Three-ton whole-home system
The published formula gives $2,650 × 3 tons = $7,950. The project still has to meet the whole-home rules; installing a three-ton system does not establish eligibility by itself.
Four-ton partial-home system
The published formula gives $1,125 × 4 tons = $4,500, before any separately earned weatherization or sizing bonus. The project does not receive the whole-home rate while retaining a supplemental boiler or furnace.
Income-qualified project
The published ceiling is not a guaranteed payment. Household income, existing heating fuel, property type, approved scope, program budget, and the delivery path determine the actual support. Start with the income-based eligibility process before accepting a contractor proposal.
HEAT Loan
The Mass Save HEAT Loan can finance qualifying improvements at 0% interest, subject to current program rules and lender approval. It is financing, not an additional rebate. Ask whether a quoted monthly payment assumes receipt of a rebate and what happens if the final rebate is lower than estimated.
Federal and state stacking
There is no 2026 federal 25C heat pump credit to add to these figures. Other local or income-based assistance may exist, but never add two advertised maximums until both administrators confirm that the same project can use both programs and explain which incentive is applied first.
Before you apply
- Open the official Mass Save heat pump page on the day you request bids.
- Save the rebate table, qualified equipment record, AHRI certificate, assessment report, contractor proposal, commissioning documents, and final invoice.
- Confirm whether the home is in Mass Save or municipal-light-plant territory.
- Ask the contractor to identify the rebate path and tonnage calculation on the proposal.
- Treat every amount on this page as a planning figure until Mass Save or its program administrator confirms the project.
What changed in this update
The August 12 review replaces the older $10,000 whole-home figure with Mass Save’s current 2026 schedule, separates whole-home, partial-home, and basic projects, and removes calculations that combined maximum incentives without confirmation.
