MassCEC offers awards to residences that install qualifying air-source heat pump (ASHP) systems, which provide highly efficient heating and cooling. Incentives are available both for qualifying mini-split (single head, multi-head, and central) systems.

This program is part of MassCEC’s $30 million Clean Heating and Cooling program, which supports technologies that provide customer cost savings and environmental benefits while maintaining a high level of comfort and reliability.

Project Eligibility

Rebates are available for new or existing homes that meet the following eligibility requirements:

  1. Have Eversource, National Grid, Unitil, or an eligible municipal light plant, as their electric provider.
  2. Use the installed air-source heat pump (ASHP) for heating consistently throughout the winter.
  3. Work with a participating installer.
  4. Install ASHPs from MassCEC’s list of eligible equipment.
  5. Have had a home energy audit completed within the last four years or have one scheduled within six months of project completion. Please read through our program FAQs for answers to questions about home energy audit requirements and exceptions.

Rebate Type Eligibility

If the project meets the above eligibility requirements, system owners should next determine which rebate type they are eligible for based this table.

**New homes and multifamily residences with more than four units do not require an energy audit. If you live in an area with a scheduling backlog, please submit an email confirming you are in the scheduling queue with your application. Please call Mass Save at 866-527-7283 to schedule.

***For purposes of determining rebate levels, MassCEC uses the system’s maximum heating capacity (BTU/hr) at 5°F.

****To receive an Income-Based Rebate, the homeowner must complete one of the accepted income-verification methods. Please see the Program Manual (section 2.4) for more information about Income-Based Rebates and income verification.

Step 1: Find an Installer 

Each homeowner should first select an eligible ASHP installer, who will help you with your rebate application. MassCEC recommends that residents:

Prior to deciding to move forward with a system, residents who may meet income criteria should determine if they are eligible for the Income-Based Rebate Adder, as described in the Program Manual Section 2.6. For example, a household of four with annual income of $130,775 or less may qualify. 

Step 2: Select Eligible Equipment

Work with your installer to select eligible equipment. You can check MassCEC's list of eligible equipment on our Eligible Residential Air-Source Heat Pumps page. 

Step 3: Apply for a Rebate 

Once you select an installer and are ready to move forward with the project: 

Within 90 days of project completion, residents, with assistance from their installer(s), should complete and email the following documents to ashp@masscec.com

  • The rebate application (attached as an Excel document).
  • A signed Residential Air-Source Heat Pump Participant’s Agreement.
  • A copy of a recent month’s electric bill showing the “service for” address and the residential rate code (typically “R1” or “R2”).
  • A copy of the paid invoice, showing model numbers, total costs and invoice date.
  • If applicable, complete income-verification. Eligibility thresholds and income verification methods can be found in the Program Manual (section 2.4) or on the income-based rebate page of our website.
  • For Projects designed to supply 100% of the building’s heat with no supplemental heat source, a copy of the summary report for the Manual J (residential) heat load calculation, as described in the Program Manual (section 2.6).

Note: If the installer is not already on MassCEC’s list of participating installers, the installer must submit the Primary Installer Agreement and qualifying certificate(s) of manufacturer training (Program Manual, section 2.5). MassCEC highly recommends that the installer submits this documentation prior to rebate-related equipment installation.

    Please read the Program Manual for full details on eligibility, program requirements and rebates. Installers looking to participate in the program, or apply on behalf of homeowners, should visit the installer resources page. 

    Step 4: Take Care of your Heat Pump

    Follow these simple tips to get the most out of your new air-source heat pump!

    Q: Where can I find the rebate application?

    • The rebate application can be found in the above How Do I Apply section, or on the Installer Resources page. 

    Q: What is the deadline for submitting the rebate application? 

    • Rebate applications must be submitted within 90 days of project installation, or they will not be considered. Installers and system owners should pay attention to additional deadlines if they plan on installing a unit that has been grandfathered into our program.

    Q: How do I check the status of my rebate?

    • Email us at ASHP@masscec.com or call us at 617-315-9357 with the applicant’s name, address, and installer’s name and we will respond as quickly as we are able.

    Q: How much will my rebate be?

    • Homeowners are eligible for a standard rebate of $625 per eligible, single-head ASHP, for up to three heat pumps.  For multi-head models, homeowners are eligible for standard rebates of up to $2,500, depending on the heating capacity of the outdoor unit. Homeowners who qualify for Income-Based Rebate Adders qualify for higher rebate levels. Visit the Eligible ASHP Model page for more information on rebate levels. 

    Q: Why isn’t everyone in Massachusetts eligible for this rebate program?

    • Projects receiving rebates through MassCEC must be located in a utility territory that contributes funding to the Renewable Energy Trust (RET), which includes communities served by investor owned electric utility companies or a participating municipal lighting plant. Additionally, MassCEC has received additional funding from the Regional Greenhouse Gas Initiative (RGGI) to support all projects that are replacing electric resistance heat, even if they located are in a municipal light plant community that does not pay into the RET. 

    Q: What is an MLP and where are they?

    • MLP stands for “municipal light plant” and refers to communities who are serviced by a publicly owned local utility instead of an investor-owned electric company, such as National Grid or Eversource. Some of these MLP communities contribute to the RET, which is the original source of our funding for rebates. We are unable to provide rebates to MLP communities that do not contribute to the RET. 

    Q: Why does the project site's electric provider partially determine eligibility? 

    • National Grid, Eversource, Unitil and eligible municipal light plants each pay into the Renewable Energy Trust (RET). The RET partially funds the rebate program and other clean energy initiatives.  Projects served by an electric utility that does not pay into the RET may apply for a rebate only if they are replacing or offsetting electric heat.

    Q: Are condos and apartments eligible for this rebate?

    • Yes, condos and apartments are eligible for rebates. Each condo unit or apartment is considered a separate project site and would need a separate application. Please include a copy of the electric bill from the participating unit. For project sites that may be new construction, please refer to our Program Manual for more information.

    Q: Can landlords apply for this rebate?

    • Yes, landlords can apply for this rebate. Each apartment unit is considered a separate project site and would need a separate application. Each project site is eligible for a rebate of up to $2,500.

    Q: Do I have to have a home energy audit completed before I apply?

    • No, however, you do have to have a home energy audit scheduled before applying. If you live in a region with a scheduling backlog, forwarding us the confirmation that you are in queue for scheduling will suffice in lieu of the audit.

    Q: Do condos or apartments require an energy audit? 

    • Yes, if the complex has 1-4 units, an energy audit is required for each participating unit.  However, energy audits are waived for buildings with 5 or more units as Mass Save does not offer energy audits for single units inside residential complexes/facilities with 5 or more units.

    Q: I receive my electricity from a municipal light plant and I’m not eligible for a MassSave home energy audit, do I still need an energy audit?

    • Yes! Most municipal light plants also provide free home energy audits to their patrons.

    Q: Does MassCEC offer energy audits? 

    • MassCEC does not offer energy audits. Free residential energy audits can be schedules through MassSave by calling 866-527-7283. Please refer to our Program Manual for more information regarding energy audit requirements. Most municipal light plants also provide free home energy audits to their patrons. Please contact your municipal light plant directly for more information.

    Q: What is the difference between the 120 percent and the 80 percent Income-Based Rebates? 

    • The 120 percent Income-Based Rebate is offered to households with income below 120 percent of the state’s median income. The total eligible rebate is increased to $800/single-head unit or $800/heating ton for central and multi-head units. This rebate amount is capped at $3,200.

      The 80 percent Income-Based Rebate is only available for households with income below 80 percent of the state’s median income AND are replacing or offsetting electric resistance heat. The total eligible rebate is increased to $1500/single-head unit or $1500/heating ton for central and multi-head units. This rebate amount is capped at $6,000.

      Please refer to our page on Income-Based Rebates as well as the Program Manual, section 2.4, for more information on income thresholds.

    Q: How can the system owner apply for the Income-Based Rebate? 

    • System owners can apply using one (1) of the three options below:

    1. Submit an electric bill with a low-income rate code, denoted by an R2 or R4.  
    2. Submit a fuel assistance letter dated from within one year.
    3. Complete the MassCEC income verification, through the MassCEC’s income verification portal.

          Please refer to our page on Income-Based Rebates as well as the Program Manual, section 2.4, for more information on income verification methods.
