Hingham’s housing stock — older colonials, coastal capes, and plenty of homes still heating with oil — makes it one of the best towns on the South Shore for a heat pump conversion. Here’s what Hingham homeowners specifically should know going into the 2026 rebate season.
Why Hingham homes are strong candidates
A large share of Hingham homes run on oil or propane — the two fuels where heat pump economics work hardest in your favor. Many also lack central air, which means a heat pump conversion solves two problems at once: efficient winter heat and whole-home cooling for humid coastal summers. If you’re skeptical a heat pump can handle a January nor’easter, read our breakdown of how cold-climate heat pumps perform in South Shore winters.
The 2026 rebate numbers
- Whole-home heat pump: $2,650 per ton, capped at $8,500
- Partial-home / dual-fuel: $1,125 per ton, capped at $8,500
- Income-qualified households: up to $16,000, or potentially no-cost installation through the Turnkey program
- 0% HEAT Loan: up to $25,000 interest-free, terms up to 7 years
The critical rule: your free Mass Save home energy assessment must be completed before installation begins, or the rebate can be forfeited. The full order of operations is in our step-by-step Mass Save rebate guide.
Keeping your boiler as backup? That works too
Plenty of Hingham homeowners aren’t ready to retire a working gas boiler — and they don’t have to. A dual-fuel setup lets the heat pump carry most of the season while the boiler handles the coldest snaps, and it still qualifies for the partial-home rebate.
