Mass Save rebate calculator
Tell us about your home and heating fuel to estimate your 2026 Mass Save rebate tier and your 0% HEAT Loan monthly payment. It's an estimate — book a free assessment and we'll confirm your exact tier and eligibility.
Estimates use 2026 Mass Save figures ($2,650/ton whole-home, capped at $8,500; up to $16,000 income-eligible; separate weatherization incentives may apply). Commercial is $2,000/ton up to 35 tons, project-by-project beyond that. The top tier requires an HPIN installer — Nexis. MLP towns run their own programs. Confirmed at your free assessment.
