Rebates & incentives in Massachusetts

HEAR live

AC-only installs see limited rebates in 2026; the big incentives go to heat pumps, which cool and heat. It's worth pricing a heat pump alongside your AC quote.

Status: Mass Save rebates are utility-funded and run year-round; the income-based HEAR top-up launched in 2025.

The federal 25C tax credit (up to $2,000 for heat pumps; $600 for high-efficiency AC or furnaces) and the 25D credit ended December 31, 2025 under the One Big Beautiful Bill Act — neither is available for 2026 installs. The remaining federal help is the IRA Home Electrification & Appliance Rebates (HEAR): up to $8,000 toward a heat pump for households under 150% of area median income, paid at point of sale where a state has launched its program.

Verified July 2026. Rebate budgets deplete and program windows change fast — confirm current amounts and eligibility with your utility and the DSIRE database before you budget. Costadia does not administer these programs.
