Air Source
Air source heat pumps commonly referred to as mini-splits or central ducted heat pumps extract heat from the outside air in the winter and use forced hot air to heat your home. This process is reversed in the summer to cool the home. Rebate amounts vary by the displacement amount of your current fossil fuel or electric resistance system.

*Tons are calculated based on AHRI cooling capacity divided by 12,000 BTUs. Rebate amount based on tons.
**Rebate not to exceed the purchase price. Equipment must be installed in individually metered 1-4 unit buildings or townhouses to receive the whole-home rebate.
**Income-qualified customers may be eligible for no-cost heat pump conversions through the comprehensive home energy assessment program. To learn more and to get started, call 1-800-797-6699.

Integrated Control Rebates (add-on): Customers with existing heat pumps and oil and propane systems that do not currently have integrated controls can receive up to $1,500 when they add them to their systems. These controls can help minimize the use of a boiler or furnace while maximizing the use of a heat pump to get maximum savings and comfort.
Air to Water
Air-to-water heat pumps extract heat from the outside air in the winter and use hydronic/radiant systems to heat your home. Rebate amounts vary by the displacement amount of your current fossil fuel or electric resistance system.
Whole-Home Heat Pump Rebates
| Equipment Type | Efficiency Requirements | Rebate Amount | Enhanced Amount (Moderate Income) |
|---|---|---|---|
| Air to Water Heat Pumps | Refer to the MassSave.com/HPQPL | $3000/ton up to $10,000 | $16,000 per home |

Ground Source
Ground source heat pumps occasionally referred to as geothermal heat pumps extract heat from the ground in the winter, which typically maintains a temperature of around 50 degrees, and can use forced hot air or radiant heat to heat your home. This process can reversed in the summer to cool the home. Rebate amounts vary by the displacement amount of your current fossil fuel or electric resistance system.
Geothermal Heat Pumps
| Equipment Type | Rebate Type | Efficiency Requirements | Rebate Amount | Enhanced Amount (Moderate Income) |

| Ground Source Heat Pumps | Whole-Home3 | Refer to the ENERGY STAR Certified list2 | $15,000 per home* | $25,000 per home |
| Ground Source Heat Pumps | Partial-Home | Refer to the ENERGY STAR Certified list2 | $2,000 per ton1, up to $15,000 | $25,000 per home |
1. Tons are calculated based on AHRI cooling capacity divided by 12,000 BTUs. Rebate amount based on tons.
2. Ground source heat pumps must be ENERGY STAR certified, qualified, listed with, and certified by AHRI, and meet the program EER and AHRI outdoor unit configuration requirements.
3. Heat Pumps installed for whole-home heating and cooling that do not meet the weatherization requirement may be eligible for partial-home rebate amounts.
