Mass Save lists 2026 residential air source heat pump rebates of $2,650 per ton up to $8,500 for whole-home systems, $1,125 per ton up to $8,500 for partial systems, and $250 per ton up to $2,500 for basic systems. The federal energy efficient home improvement credit no longer applies to new installs: the IRS says it covered property placed in service before December 31, 2025.
Mass Save is the main heat pump incentive left for Massachusetts homeowners in 2026. Amounts below are from the Mass Save air source heat pump page as of October 8, 2026. Rebates change, so confirm the current figures and rules there, or with your installer, before you sign a contract.
How Much Are Mass Save Heat Pump Rebates in 2026?
| Installation type | Rebate per ton | Maximum |
|---|---|---|
| Whole-home | $2,650 | $8,500 |
| Partial-home | $1,125 | $8,500 |
| Basic | $250 | $2,500 |
| Income-based enhanced incentives | Up to $16,000, or up to no cost through Turnkey Services | |
Mass Save calculates tons from the unit's AHRI cooling capacity divided by 12,000 BTUs, and bases the rebate on that number. So a 3-ton whole-home system works out to 3 × $2,650 = $7,950, and anything above about 3.2 tons hits the $8,500 cap. For scale, This Old House puts a typical central heat pump installation at $10,575.
Mass Save is brought to you by Berkshire Gas, Cape Light Compact, Eversource, Liberty, National Grid and Unitil. It also notes that heat pumps will likely increase your electric usage, and that many customers offset this by reducing or eliminating other heating fuel costs, such as oil or propane.
What Is the Difference Between Whole-Home, Partial and Basic?
The tiers follow how much of the home the heat pump is designed to heat, from the whole house down to smaller installs. Mass Save sets the exact definitions, including what has to happen to the existing heating system, so read them on the Mass Save page before choosing a design. The difference matters: the whole-home rate per ton is more than twice the partial rate.
Which Heat Pumps Qualify?
Look at the NEEP cold-climate air source heat pump list. NEEP says efficiency programs including Mass Save reference it, and it identifies units suited to heat efficiently at 5°F and below without supplementary electric heat. Ductless, ducted and ducted mini split models all appear on the list.

Ask About Heat PumpsIs There Still a Federal Tax Credit for Heat Pumps?
No, not for new installs. The IRS says the energy efficient home improvement credit is allowed for qualifying property placed in service on or after January 1, 2023, and before December 31, 2025. While it ran, heat pumps had a $2,000 annual limit. Older articles that still quote a 30% federal credit are out of date.
How Should You Plan Around the Rebate?
- Confirm the current amounts and rules on the Mass Save page before you sign.
- Ask the installer which tier the design qualifies for and who files the paperwork.
- Choose equipment from the NEEP cold-climate list.
- Keep every invoice and product document; the rebate form needs them.
