How much is the Mass Save heat pump rebate in 2026?

The Mass Save whole-home heat pump rebate in 2026 is $2,650 per ton, capped at $8,500 per home. The lower partial-home tier pays $1,125 per ton (same $8,500 cap), and a new basic tier pays $250 per ton (capped at $2,500).

Do I still get a federal tax credit for a heat pump?

No. The federal Section 25C heat pump credit and the Section 25D geothermal credit both expired December 31, 2025 under the One Big Beautiful Bill Act. Property placed in service after that date does not qualify.

What is the Mass Save HEAT Loan?

Whole-Home Heat Pump Rebate

$2,650 /ton

Capped at $8,500 per home

The installed heat pump must be the sole source of heating and cooling for the spaces served. Equipment must be ENERGY STAR Cold Climate certified and listed on the Mass Save Heat Pump Qualified Products List (HPQPL). A Manual J load calculation is needed to qualify for the sizing bonus and is industry-standard practice on Mass Save projects.

Partial-Home / Supplemental Heat Pump Rebate

$1,125 /ton

Capped at $8,500 per home

Heat pump installed alongside an existing primary heating system. Equipment must be on the HPQPL. Lower per-ton rebate reflects supplemental rather than sole-source use.

Basic Heat Pump Rebate

$250 /ton

Capped at $2,500 per home

New for 2026. Applies to replacing an existing heat pump with a new qualified HPQPL-listed heat pump, or conditioning a previously unconditioned space.

$500 Right-Sized Equipment Bonus Partial-home

Partial-home installs only. Equipment must be sized to meet 90–120% of the total heating load at the outdoor design temperature, documented via an ACCA Manual J load calculation submitted with the rebate application.

$500 Weatherization Bonus Partial-home

Partial-home installs only. Requires a Mass Save Home Energy Assessment plus installation of the recommended weatherization (typically air sealing and insulation) within one year prior to or up to six months after the heat pump installation.

Financing

Mass Save HEAT Loan

0% APR up to $25,000

Below 135% of State Median Income: 7 years (84 months)
135%–300% of State Median Income: 5 years (60 months)
Over 300% of State Median Income: 3 years (36 months)

Subject to bank underwriting through participating Massachusetts lenders. Covers equipment + installation costs for qualifying high-efficiency upgrades (heat pumps, ductless mini-splits, insulation, water heaters). Households below approximately 81% SMI typically route to Mass Save's no-cost / enhanced-rebate programs rather than the HEAT Loan.

No federal heat pump tax credit applies in 2026.

Section 25C Energy Efficient Home Improvement Credit (heat pump portion) (30% of cost up to $2,000 annually for qualifying heat pump installations (inflation reduction act expansion)) ended for property placed in service after 2025-12-31 under the One Big Beautiful Bill Act (P.L. 119-21).
Section 25D Residential Clean Energy Credit (geothermal portion) (30% of installed cost for ground-source (geothermal) heat pumps, with no dollar cap) ended for property placed in service after 2025-12-31 under the One Big Beautiful Bill Act (P.L. 119-21).

Status as of 2026-05-27: neither 25C nor 25D has been reinstated or replaced by Congress. Pending bills (e.g. H.R. 616) have not advanced. Pre-2026 §25D installs may carry forward unused credits.
