Heat Pump Rebates in Boston, Massachusetts (2026)

Boston is one of the strongest US heat pump markets thanks to Mass Save Whole-Home Heat Pump Rebate (up to $10,000), high heating oil and natural gas prices, and a state policy framework actively pushing fossil fuel displacement. Combined with federal 25C (30% up to $2,000), HEEHRA (income-qualified up to $8,000), and Mass Save HEAT Loan (0% APR up to $50,000), Boston whole-home heat pump installs frequently see 65–80% effective cost coverage. NEEP Cold Climate ASHP equipment is essentially required for full Mass Save rebate. Many Boston homeowners pair heat pump install with whole-home weatherization through Mass Save Home Energy Assessment to maximize stacked rebate value.
