- SMART 3.0 production incentive, paid for 20 years (residential)
- $1,000 MA state income-tax credit
- State sales-tax & added-value property-tax exemptions
Figures as of 2026; SMART/utility eligibility verified per address. We'll show you ownership vs. third-party options.
HEAT PUMP INCENTIVES
Up to $8,500
- Up to $8,500 in Mass Save whole-home rebates
- Up to $16,000 if income-eligible
