Local Incentives
Waltham, MA Heat Pump Rebates & Incentives
Local and federal incentive programs can significantly reduce the cost of a new heat pump system. Here are the programs available to Waltham homeowners.
Mass Save Heat Pump Rebate
Up to $8,500
Massachusetts' premier energy efficiency program offering rebates for air source heat pump installations. Provides whole-home and partial-home rebate options based on system type and heating displacement.
Eligibility: Residential customers in 1-4 unit homes with participating utilities (National Grid, Eversource, Unitil, Cape Light Compact). Equipment must be ENERGY STAR Cold Climate certified and installed by a Mass Save contractor. Whole-home systems require sufficient weatherization and removal/disconnection of existing fossil fuel heating.
Waltham homeowners can access the Mass Save heat pump rebate program, which offers up to $8,500 for qualifying installations in 2026. Rebate amounts depend on whether you're replacing your entire heating system (whole-home) or supplementing existing heating (partial-home).
Climate Zones
Waltham sits in IECC Climate Zone 6, which means cold winters (design temps down to -5°F) and warm summers (up to 91°F). This wide temperature range makes proper heat pump sizing critical—you need a system that can handle both extremes efficiently.

Repair versus replace
When a heat pump is in need of repair it is worth considering whether a replacement would be a better investment. While each case is unique, we generally recommend investing in a new unit when repairs exceed $5,000.
Potential repair | Cost range | Description
| --- | --- | --- | | Capacitor Replacement | $150 - $400 | Common issue when unit struggles to start or makes a humming noise. Capacitors store the electrical energy needed to start the compressor and fan motors. | | Refrigerant Recharge | $250 - $750 | Needed when the system loses cooling or heating efficiency due to low refrigerant levels. | | Reversing Valve Replacement | $450 - $900 | Required when the unit cannot switch between heating and cooling modes. | | Compressor Replacement | $1,500 - $3,000 | Major repair needed when the unit fails to heat or cool entirely. | | Evaporator/Condenser Coil Replacement | $1,200 - $2,800 | Replacement needed when coils develop leaks or corrosion that cannot be economically repaired. | | Control Board Replacement | $500 - $1,200 | Required when the system has electrical failures or erratic behavior. | | Full System Replacement | $4,500 - $8,000+ | When repairs exceed the value of the unit or multiple major components fail simultaneously. |
