Massachusetts Heat Pump Rebates & Incentives Guide

Unlock savings on heat pumps in Massachusetts. Explore Mass Save, federal tax credits, and local utility rebates to lower installation costs and boost energy efficiency in your MA home.

Quick Answer: Massachusetts Heat Pump Rebates Overview

Mass Save is the primary resource for most Massachusetts residents seeking heat pump rebates. This program, funded by the state's major electric and gas utilities, offers cash rebates for qualifying heat pump installations, including air-source, ground-source, and heat pump water heaters. Check masssave.com for current rebate amounts, which are updated periodically and vary by equipment type.

Two additional savings opportunities are available:

Federal tax credits. IRS §25C (Energy Efficient Home Improvement Credit) offers a 30% credit, up to $2,000 annually, for qualifying heat pump installations. This is a tax credit that reduces your tax liability, not a direct payment. It can be combined with Mass Save and local utility rebates.

Local municipal utility programs. If your electricity or gas is supplied by a municipal utility instead of Eversource or National Grid, your utility might offer its own rebate program alongside Mass Save. Several of these are detailed below.

These programs can be combined. Stacking Mass Save, municipal utility, and federal §25C credits can significantly reduce the net cost of a heat pump system.

Understanding Mass Save Heat Pump Rebates in Massachusetts

Mass Save is a collaborative program managed by Massachusetts' major investor-owned utilities and energy suppliers: Berkshire Gas, Cape Light Compact, Eversource, Liberty, National Grid, and Unitil (Mass Save - Residential Energy Efficiency Programs, DSIRE).

The program aims to lower residential energy costs by offering cash incentives for upgrading to energy-efficient heating, cooling, water heating, and appliance systems. Heat pumps are specifically listed as eligible technology, along with smart thermostats, ENERGY STAR appliances, and induction cooktops.

What Mass Save Covers for Heat Pumps

Mass Save supports several types of heat pumps:

Air-source heat pumps (ducted and ductless mini-split systems)
Ground-source (geothermal) heat pumps
Heat pump water heaters

Rebate amounts are determined by the utilities' three-year energy efficiency plans and are updated regularly. Current figures are available on masssave.com; third-party websites may have outdated information.

How to Access Mass Save Rebates

To access Mass Save rebates, visit masssave.com, confirm your utility's participation, schedule a home energy assessment if required, have the system installed by an approved contractor, and submit the rebate application with necessary documentation. The Mass Save website provides detailed instructions and hosts the application portal.

Local Municipal Utility Heat Pump Programs and Incentives

Municipal utilities offer separate rebate programs. Investigate these before signing installation contracts.

Wakefield Municipal Gas and Light Department (WMGLD)

WMGLD offers an Incentive Rebate Program for residential customers focusing on energy efficiency improvements, including heat pumps. A maximum rebate of $1,500 per qualifying customer annually is available for energy efficiency improvements (Wakefield Municipal Gas and Light Department - Residential Conservation Services Program, DSIRE). Key requirements include a mandatory pre-installation audit through the NextZero program and a post-installation inspection before rebate issuance. Installing the system before the audit may disqualify you. Contact WMGLD directly at wmgld.com for current program details.

Chicopee Electric Light Department (CELD)

CELD provides rebates specifically for heat pumps, heat pump water heaters, and various other energy-efficient appliances for residential customers (Chicopee Electric Light Department - Residential Energy Efficiency Rebate Program, DSIRE). The program is managed by EFI Municipal Rebates. Application forms are available on CELD's program website at celd.com. Review current program terms before purchasing equipment, as eligibility and rebate amounts can change.

Concord Municipal Light Plant (CMLP)

CMLP offers residential rebates covering heat pumps, water heaters, weatherization, solar PV, and electric vehicles (Concord Municipal Light Plant - Residential Energy Efficiency Rebate Program, DSIRE). Program details are available at concordma.gov. Confirm current offerings before installation.

Cape Light Compact (CLC)

Cape Light Compact serves Cape Cod and Martha's Vineyard. It acts as both a Mass Save administrator and a municipal aggregator with its own residential rebate program. Heat pump installations must be done by a pre-approved contractor, who will provide the rebate form directly (Cape Light Compact - Residential Energy Efficiency Rebate Program, DSIRE). Using a contractor not on the approved list will forfeit the rebate. Find the approved contractor list and current incentive amounts at capelightcompact.org.

Marblehead Municipal Light Department (MMLD)

MMLD participates in the NEXTZERO program through MMWEC (Massachusetts Municipal Wholesale Electric Company). NEXTZERO offers home energy audits, energy education, assistance with energy improvements, and ENERGY STAR appliance rebates (Marblehead Municipal Light Department - Residential Energy Efficiency Rebate Program, DSIRE). Equipment eligibility and specific rebate amounts are detailed in the rebate guide on MMLD's website at marbleheadelectric.com. Contact MMLD directly for current program status.

Stacking Federal Tax Credits with Massachusetts Rebates

Federal incentives can be combined with state and local rebates.

IRS §25C: Energy Efficient Home Improvement Credit

This is the main federal credit for heat pump installations. Under IRS §25C, you can claim a 30% tax credit on the cost of a qualifying heat pump, up to a $2,000 annual limit for heat pumps. A separate $600 limit applies to electrical panel upgrades, and $150 applies to a qualifying home energy audit. These are annual limits, not lifetime caps (IRS §25C; IRS.gov).

To qualify, the heat pump must meet CEE Tier efficiency standards or be ENERGY STAR Most Efficient certified. Your installer should provide an AHRI certificate confirming the equipment meets the standard. Claim the credit on IRS Form 5695 when filing your federal return.

This credit can be combined with Mass Save and municipal utility rebates.

IRA §50123: High-Efficiency Electric Home Rebate Act (HEAR)

The HEAR program provides up to $8,000 for a qualifying heat pump HVAC system and up to $1,750 for a heat pump water heater. Unlike §25C, this is a point-of-sale rebate, not a tax credit. It has an income limit of 150% of the area median income (AMI). This program is administered at the state level. Confirm Massachusetts rollout details with the Massachusetts Clean Energy Center or Mass Save.

HEAR rebates can be combined with §25C but not with IRA §50122 HOMES rebates for the same measure.

IRA §50122: HOMES Rebate Program

This program offers performance-based rebates of up to $8,000 for households that achieve 35% or greater modeled energy reduction. Low-to-moderate income (LMI) households receive double the standard rebate amounts. This program cannot be combined with HEAR for the same measure but can be combined with §25C. Confirm Massachusetts program status with the Massachusetts Clean Energy Center.

Credit/Rebate	Type	Max Amount	Income Limit	Stackable with Mass Save?
IRS §25C	Tax credit	$2,000/yr (heat pumps)	None	Yes
IRA §50123 HEAR	Point-of-sale rebate	$8,000 (HVAC HP)	150% AMI	Yes
IRA §50122 HOMES	Performance rebate	$8,000	Income-scaled	Yes (not with HEAR on same measure)

Eligibility Requirements and Application Process for MA Heat Pump Rebates

Common Eligibility Criteria

Most Massachusetts heat pump rebate programs share these requirements:

You must be a residential customer of the administering utility.
Installed equipment must meet specific efficiency ratings. Mass Save programs generally require ENERGY STAR certification at a minimum. Federal §25C requires CEE Tier or ENERGY STAR Most Efficient designation.
Installation must be performed by a licensed HVAC contractor. Some programs, including Cape Light Compact, require contractors from a pre-approved list (Cape Light Compact - Residential Energy Efficiency Rebate Program, DSIRE).
Some programs, like WMGLD, require a pre-installation energy audit through NextZero before any work begins (Wakefield Municipal Gas and Light Department - Residential Conservation Services Program, DSIRE).

General Application Process

Confirm your utility and program. Visit masssave.com or your municipal utility's website to verify eligibility.
Schedule a home energy assessment if required. Mass Save offers free home energy assessments. Some municipal programs mandate this step. Skipping it can forfeit the rebate.
Select qualifying equipment. Confirm the specific model meets the efficiency standards for each program you plan to claim. Obtain the AHRI certificate from your contractor.
Hire a qualifying contractor. For Cape Light Compact and some other programs, you must choose from an approved list. For Mass Save generally, the contractor must be licensed. Verify this before signing a contract.
Complete installation and retain all documentation. Keep your invoice, equipment model numbers, AHRI certificate, and contractor license information.
Submit your rebate application. Most programs accept online submissions via their websites. Federal §25C is claimed on IRS Form 5695 at tax time.

A common mistake is purchasing or installing equipment before confirming eligibility. Program terms change, and a system that qualified previously might not qualify now.

What Changed Recently in Massachusetts Heat Pump Incentives?

The Green Communities Act Foundation

Massachusetts heat pump incentive programs exist due to a specific legislative mandate. In 2008, Governor Deval Patrick signed S.B. 2768, the Green Communities Act (GCA). This law required electric and gas utilities to prioritize cost-effective energy efficiency over new energy supply. It also directed utilities to submit three-year energy efficiency plans detailing how they would meet this requirement (S.B. 2768, Green Communities Act; Energy Efficiency First Fuel Requirement, DSIRE).

Utilities are legally required to fund and administer energy efficiency programs, ensuring consistent funding for Mass Save.

The 2025-2027 Three-Year Plan

The current framework for Massachusetts utility energy efficiency programs is the 2025-2027 three-year plan, submitted by the participating utilities and overseen by the Massachusetts Energy Efficiency Advisory Council (MA EEAC). This plan establishes funding levels, program structures, and eligible measures for the current period, including heat pump rebates (MA EEAC; Energy Efficiency First Fuel Requirement, DSIRE).

The three-year plan structure means that rebate amounts and program terms are reviewed and potentially revised every three years, with the EEAC providing oversight. Check ma-eeac.org or masssave.com for current program specifics and rebate amounts.

The GCA's Energy Efficiency First Fuel Requirement drives program evolution, expanding heat pump and electrification incentives.

Federal Tax Considerations

Heat pump rebates can provide significant federal tax benefits under specific sections of the Internal Revenue Code (IRC). Notably, IRC § 25C and § 25D offer credits for the installation of qualifying heat pumps, which can help offset costs for both businesses and individuals in Massachusetts.

IRC § 25C: Provides a 30% tax credit on the cost of qualifying heat pumps and heat pump water heaters, with an annual cap of $2,000, separate from the $1,200 general envelope cap.
IRC § 25D: Offers a 30% uncapped tax credit for geothermal heat pumps (ground-source), provided the equipment meets the highest efficiency tier set by the Consortium for Energy Efficiency (CEE) or is ENERGY STAR Most Efficient.
Form 5695: Tax credits under both IRC § 25C and § 25D are claimed using Form 5695, which must be filed with your federal tax return.
Eligibility Requirements: Ensure that the heat pump or geothermal system meets the necessary efficiency standards to qualify for the credits.
State Conformity: While federal tax benefits apply, verify with a Massachusetts CPA regarding any state-specific implications or decoupling from federal rules.

This is not tax advice — consult a CPA familiar with Heat pump rebates for your specific situation.
