Mass Save Rebates in 2025
Mass Save is Massachusetts’s nation-leading energy efficiency incentive program. In 2025, homeowners and builders can access significant rebates for insulation, heat pumps, air sealing, smart thermostats, and more. A certified HERS rating is often required to qualify for the highest rebate tiers.
2025 Mass Save Rebates for New Construction
For new construction projects, Mass Save offers rebates based on HERS score achieved. The more energy efficient the home, the larger the rebate. Projects achieving HERS 40 or below qualify for the maximum new construction incentives, which can exceed $5,000 per home.
