The flagship Mass Save rebate for cold climate air source heat pumps. Amount depends on your utility (Eversource/National Grid: $2,650/ton, Unitil: $2,000/ton) and system size. Maximum $8,500 for the heat pump itself plus a $500 sizing quality bonus.
Households at or below 80% Area Median Income (AMI) qualify for a dramatically enhanced rebate on top of the standard rebate. For a family of 4 in most MA counties, this is approximately income under $90,000.
The Inflation Reduction Act created a 30% tax credit on qualifying HVAC equipment. This is a direct tax credit (not deduction) filed on IRS Form 5695 with your annual taxes.
Replace your electric or oil water heater with a qualifying heat pump model. These units are 3x more efficient than standard electric water heaters.
Qualifying smart thermostats reduce energy use by 10-15% through intelligent scheduling, occupancy sensing, and utility demand response.
Insulation dramatically improves heat pump efficiency. Most MA homes built before 2000 have significant insulation gaps. We recommend a combined heat pump + insulation project for maximum benefit.
Customers of municipal electric utilities in Massachusetts qualify for an additional $500 on top of the standard Mass Save rebate.
Several Massachusetts cities offer additional rebates on top of Mass Save, funded by municipal sustainability programs.
Our calculator uses the same formulas as licensed HVAC engineers and Mass Save program administrators. Here's exactly how every number is derived.
These coefficients are derived from ASHRAE Manual J methodology adjusted for the Massachusetts climate zone (5A/6A). The actual Manual J calculation considers R-values, window area, infiltration, and orientation — which we perform on-site during your free assessment.
Based on MA average energy prices (EIA 2024) and measured heat pump performance data. Oil savings assume ~$4.20/gallon and gas savings assume ~$1.65/therm.
