What has to be true
- The installer is in the Mass Save Heat Pump Installer Network.
- The heat pump replaces oil, propane or electric resistance heat (or natural gas, where a Mass Save gas sponsor serves you), and the home is occupied full time in winter.
- A whole-home rebate also needs the weatherization test described on the heat pumps page.
- The rebate cannot exceed the installation cost, and cannot be combined with other Mass Save incentives for the same equipment.

Common questions
Is this what I will pay?
No. It is an estimate from Mass Save's published rebate rates and the quote you type in. Our quote and Mass Save's review decide the real numbers.
Who gets the rebate money?
You apply to Mass Save with the paperwork from your job, and Mass Save pays the rebate. It asks for about eight weeks to process.
What if I do not know my tons?
Drag the size slider and watch the rebate change. Not sure? Leave it at 3; the installer works out the real size. If you already have a quote, tap "I have a quote", type the size in tons or BTU per hour (the calculator divides BTU by 12,000 to get tons) and add the price. The installer's load calculation sets the real size, so the number can change. A whole-home rebate hits the cap at about 3.2 tons in 2026.
Where does the price come from?
You type your quote. With no quote, a whole-home estimate uses Mass Save's own average whole-home installation cost, $22,000, from program data for installs finished in 2022, and labels it as the average. Prices today may differ.
