What Mass Save actually pays
A standard heat pump rebate runs $8,500 to $9,500. Income-qualified households can reach $25,000. Insulation is 75% covered for everyone, 100% free below 60% of area median income. Add solar, battery storage, water heater, windows, EV charger, and smart thermostat rebates, and a single program covers all 8 categories we track — administered consistently across the state's utilities rather than fragmented city by city or utility by utility.
That combination — genuinely large numbers, one coherent administrator, funding that's actually open right now — is rare. It's the reason Massachusetts became our first US market instead of staying a "someday" state.
What research turned up once we started building
The rebate amounts were the easy part to document. What took longer, and what most competitor content skips entirely, were two things:
- A documented rebate-delay crisis — CBS Boston's I-Team ran multiple investigations, and the Massachusetts Attorney General's office logged more than 30 formal complaints in a single year, some homeowners waiting close to six months for a check.
- 41 Massachusetts towns run their own municipal electric utility and are structurally locked out of Mass Save entirely — a real, common source of confusion that almost nobody explains clearly.
We built content around both, because a rebate guide that only publishes the good news isn't actually useful to someone about to spend $12,000 on a heat pump.
