Key takeaways
- Mass Save is a program sponsored by Massachusetts utilities and energy efficiency providers. Incentives and eligibility change.
- We do not publish rebate amounts because they change. Confirm the current terms on the official Mass Save site before you decide.
- Many programs require an assessment or pre-approval before work begins. Starting too early can cost you an incentive.
- Ask your contractor whether the equipment you are considering qualifies, and get the model numbers in writing.
- Incentives should never be the only reason to choose a system. The system still has to fit your house.
What Mass Save is
Mass Save is the name for a collaboration of Massachusetts gas and electric utilities and energy efficiency providers that offers programs to help residents use less energy. Those programs have included incentives for efficient heating and cooling equipment, support for insulation and air sealing, home energy assessments, and financing options on qualifying upgrades. The official site is masssave.com.
Heat pumps have been a major focus of those programs for years. Details, such as which equipment qualifies, how much is offered, and who is eligible, change over time and may depend on your utility, your income, and what your house currently uses for heat. That is why this article does not list dollar figures. Any number we printed would risk being out of date by the time you read it.
How the process usually works
Programs differ in their details, but homeowners generally run into a similar sequence of steps. Check the current requirements on the official site, and ask your contractor what they know.
- Learn what is available: Read the current heating and cooling pages on the official program site, and note the eligibility rules and any deadlines.
- Consider a home energy assessment: Many homeowners start with an assessment, which can identify insulation and air sealing opportunities and may be a requirement for some incentives.
- Get a contractor quote: Ask for the make and model numbers of the equipment and whether the company is familiar with the program paperwork.
- Confirm qualification before you sign: Check that the specific equipment qualifies and whether pre-approval is needed.
- Complete the installation: Keep invoices, model and serial numbers, and any commissioning documents.
- Submit the paperwork: Follow the instructions and the deadline. Some incentives are applied by the contractor and some are claimed by the homeowner.
What to ask before you buy
Questions for the program and your contractor
- Which models qualify, and does the quote name the exact model numbers?
- Is a home energy assessment or pre-approval required?
- Does my current heating fuel or my income change what I qualify for?
- Does the incentive depend on the heat pump replacing a particular system or being the main heat source?
- Who applies for the incentive, the contractor or me?
- How long does it take to receive it, and what documents are needed?
- Are there financing options, and what are the terms?
- What happens if the rules change between my quote and my installation?
Incentives do not design the system for you
An incentive can improve the economics of a heat pump, but it cannot fix a bad fit. A house that loses a lot of heat may need air sealing and insulation before a heat pump performs well, and some incentives are tied to those upgrades for that reason. A system that is poorly sized, poorly placed, or badly commissioned will disappoint no matter how much of its cost was rebated.
Judge a project on whether it solves your comfort and operating cost problem. If it does and an incentive helps, good. If a bigger incentive tempts you toward a system that does not suit the house, step back. See our guide to types of residential heating and cooling systems and our comparison of heat pumps and furnaces.
| Question | Incentive thinking | Design thinking |
|---|---|---|
| How do I choose equipment? | What qualifies for the biggest rebate? | What suits my house and my winter, then does it qualify? |
| How many units? | Whatever the program covers | What each room and the heating load require |
| What about backup heat? | Remove the old system to qualify | Decide on risk and cost, and confirm the rules |
| What about air sealing? | Skip it, to save money | Do it first when it makes a heat pump work better |
Common mistakes that cost homeowners an incentive
Most lost incentives come down to timing and paperwork, not eligibility. These are the patterns to avoid.
- Signing before checking. Buying equipment or starting work before confirming that an assessment or pre-approval is not required.
- Vague quotes. A quote that says heat pump without a model number makes it hard to confirm qualification.
- Missing documents. Losing the invoice, model and serial numbers, or commissioning records needed for the claim.
- Missed deadlines. Many programs have submission windows. Put the date in your calendar the day the work is finished.
- Assuming last year's rules. Programs update, sometimes more than once a year. What a neighbor received may not apply to you.
- Designing for the rebate. Choosing equipment because it carries a larger incentive rather than because it fits the house.
Other programs to ask about
Beyond Mass Save, there may be other programs that affect heating and cooling projects, such as federal incentives, municipal programs, and utility offers. Federal tax credits for efficient equipment have changed in recent years, and you should check the current status with the IRS or a tax professional before you count on one. We are not tax advisors and we do not quote credits.
If you are weighing a project, ask us what we know about the current paperwork. Our heat pumps and ductless mini-splits page explains how we plan an installation, and our cost guide explains what the price depends on.
