❓Common Questions

As of January 1, 2026, the maximum whole-home heat pump rebate dropped from $10,000 to $8,500. However, new stackable bonuses of $500 for proper sizing and $500 for weatherization can bring the total potential rebate back up to $9,500 for qualifying projects.

New EPA mandates effective January 2026 require systems to use low-GWP refrigerants like R-454B or R-32. This transition has added approximately 10-15% to equipment costs due to redesigned components and safety features required for these mildly flammable (A2L) refrigerants.

Boston costs are roughly 15-20% higher due to a combination of high union labor rates (averaging $37.38/hr for techs) and the complexity of working in older housing stock; 50% of Boston homes were built before 1940, often requiring expensive ductwork retrofitting.

No, the $2,000 federal tax credit for whole-home heat pump installations authorized under the Inflation Reduction Act expired at the end of 2025. Homeowners must now rely primarily on state-level Mass Save incentives and 0% HEAT Loan financing.
