How to Claim Your Rebate — Step by Step

  • 1. Start with a free Home Energy Assessment. Eversource and National Grid — the utilities serving our Mansfield and Braintree service area — fund a no-cost visit that identifies which rebates your home qualifies for and is required before most rebates and the HEAT Loan.
  • 2. Choose qualifying equipment with a participating contractor. CleanTap can help confirm the specific model numbers and efficiency ratings (like UEF or AHRI ratings) that Mass Save requires for full rebate value.
  • 3. Install the equipment. Keep all invoices, model/serial numbers, and proof-of-purchase documentation — Mass Save requires these for rebate processing.
  • 4. Submit your rebate paperwork. Applications are typically submitted online or by mail within 60 days of installation; CleanTap can help make sure everything is filled out correctly the first time.
Pair your rebate with 0% financing.
Check My Eligibility

Rebates reduce your equipment cost up front — but for the balance, most Massachusetts homeowners pair them with the 0% Mass Save HEAT Loan (up to $25,000, no fees) or explore other financing options if the loan doesn’t fully cover your project.

Frequently Asked Questions

How much can I save with Mass Save rebates?

It depends on your project and household income. A whole-home heat pump can bring in up to $8,500 in standard rebates (or up to $16,000, or no cost, for income-eligible households), a heat pump water heater adds $750–$1,500, and weatherization can be 75–100% covered. Many CleanTap customers combine several rebates on the same project.

Do I need a home energy assessment?

Yes for most rebates and required for the 0% HEAT Loan. The free Mass Save Home Energy Assessment (funded by Eversource and National Grid) identifies air sealing and insulation opportunities and confirms which rebates apply to your home before you buy equipment.

Can I combine rebates with the 0% HEAT Loan?

Yes. Rebates lower your equipment cost, and the Mass Save HEAT Loan lets you finance the remaining balance at 0% APR, up to $25,000, with no fees. Most CleanTap customers use both together.
