Understanding the 2026 Mass Save Heat Pump Rebates
We’ll focus specifically on the rebates available for heat pump systems in Massachusetts, and how to best take advantage of the savings suited for your situation.
Currently, the rebates available for heat pump systems are broken down into three categories: Whole-Home Rebates, and Partial-Home/Supplemental Rebates.
Regardless of the type of Mass Save Heat Pump rebate, rebate form and supporting documentation must be received by February 28, 2027. Many contractors, like Endless Energy offer upfront rebates for eligible customers!
Mass Save Whole-Home Rebate
For residents looking to replace their current heating and cooling system with a much more efficient heat pump system and get off fossil fuel completely, the Whole-Home rebate is the best option for you.
Right now, for residential single family or multifamily (up to 4 units) customers, Mass Save is offering a rebate of $2,650 per ton up to $8,500. This rebates apply towards whole home heat pump systems displacing existing natural gas, oil, propane or electric resistance systems.
Additionally some customers may be eligible for enhanced incentives heat pump rebates, which offers heat pump incentives at up to $16,000 or up to no cost through Turnkey Services.
To be eligible in 2026 the eligibility requirements are:
- Equipment must be installed by a contractor participating in the Mass Save Heat Pump Installer Network (Endless Energy is also a member of the Mass Save Heat Pump Leader Network) between January 1, 2026 and December 31, 2026.

- Equipment must be new and installed to displace oil, propane, natural gas, or electric baseboard (resistance) as the primary heating system. Customers as of January 1, 2024 are required to remove or disconnect their existing system. If you are not removing the system what this means is Endless Energy will disconnect the pre-existing thermostats from both the system board and walls. In the event of emergency our service team can reconnect these controls.
- Home must be sufficiently weatherized prior to heat pump installation. There are three ways to meet this criteria: A) Your home was built during or after 2000

Mass Save Partial-Home Rebate
Not looking to replace your whole home heating and cooling system and want to consider a dual fuel option also known as hybrid heat pump…or even offset your existing system in only part of your residence? That’s okay too!
For Massachusetts single family or multifamily residents looking to add onto their existing heating system, look no further than the Partial-Home/Supplemental rebates! In 2026, Mass Save is offering $1,125 per ton, with a maximum rebate available of $8,500. So, if you’re just looking to heat or cool a small section of your home, this is the right rebate for you.
To be eligible in 2026 the eligibility requirements are:
- Equipment must be ENERGY STAR® Cold Climate certified and on Mass Save’s Qualified Product List (QPL).Endless Energy will let you know which systems proposed meet this criteria.
- An integrated control from the Mass Save Integrated Control Qualified Product List must be installed for heating zones where propane, oil, or natural gas will remain in use. If you are displacing the existing system in the specific zone of the house, integrated controls are not required.
While going forward with a Mass Save Home Energy Assessment is not required and installed recommended weatherization or insulation is not required, for efficient performance of your heat pump system it is strongly recommended.
Don’t forget if you are looking to access the 0% 7 year financing available via the Mass Save HEAT Loan, a Mass Save Home Energy Assessment is the place to start! You can book both your HVAC consolation and your Mass Save Home Energy Assessment with Endless Energy.

Which Heat Pump Systems are Covered by the 2026 Mass Save Program Rebates?
The best part about the 2026 Mass Save Program rebates is that they are geared toward cold climate heat pump systems, which heat well and work efficiently during our Massachusetts winters!
Whether you’re a customer with existing ductwork looking to update your current heating system, or looking for a whole home solution that best fits your needs; chances are you qualify for the 2026 Mass Save Program rebates.
Ducted Systems vs. Ductless Systems; Mass Save Rebates Covers Both!
While both ducted and ductless systems work on very similar principles, both have more overall energy efficiency than boilers or furnaces for your heating and cooling needs. As a result both ducted and ductless heat pump systems meeting cold climate criteria and on the Qualified Product List are rebate and HEAT Loan eligible by Mass Save!
Not sure if you’re best suited for a ducted or ductless system in your home? Let’s take a look at some of the differences between the two so you can get a better idea of what’ll best work for your situation.
Ducted Systems
Ducted systems are best for customers with duct work already in their homes. A ducted system typically consists of one outdoor unit, and the central indoor unit that pumps the air through the existing ductwork.
If you don’t already have ductwork in your home, there’s always the option to add new ductwork, but typically that can get expensive. That’s where the ductless systems shine best!
Ductless Systems
Ductless systems, also referred to as “Mini Split heat pumps,” are a more flexible option for customers who don’t have existing ductwork, or are only looking to partially upgrade their heating and cooling systems.
Ductless systems offer zone heating and cooling, due to their multi unit designs. They’re also great options to heat workshops or garages, and can be controlled independently as needed.
Customers all over Massachusetts are making the switch to ductless systems, and with the available Mass Save Program heat pump rebates, it makes sense!
