Elephant Energy’s Ultimate Guide to Mass Save Rebates

At Elephant Energy, our goal is to help you create a comfortable and sustainable home. That’s why we’re thrilled to share our ultimate guide to Mass Save rebates, designed to make your journey to energy efficiency easier and more affordable.

Whether you reside in Weymouth, Boston, Milton, or anywhere else in Massachusetts, the Mass Save program is here to help you save significantly on energy-efficient solutions, including heat pumps, heat pump water heaters, induction ranges, and more.

But how do Mass Save rebates work? Who qualifies? Will Mass Save rebates continue to work in 2024 and beyond? And what upgrades, specifically, are eligible for these incentives? Here, we break down everything MA residents need to know about Mass Save rebates.

*Eligibility for Mass Save programs is limited to individuals residing in the service territories of Eversource, National Grid, Liberty, Berkshire Gas, or Unitil (Eversource territory includes Cape Light Compact).

What Is the Mass Save Program? 

Mass Save is a group of utility companies in Massachusetts that work together with the MA Department of Energy to provide services, rebates, incentives, training, and more. Through their programs, they aim to empower and enable residents to reduce their carbon emissions and make electrification upgrades that benefit individual households, local communities, and the entire state. 

Though Mass Save offers many programs, today we’ll focus on their rebates and incentives for residential energy efficiency upgrades. 

What Are Mass Save Rebates?

Mass Save offers rebates and incentives on heating and cooling systems, appliances, weatherization upgrades, and more to help improve energy efficiency and whole-home comfort. These rebates and incentives are available to Massachusetts homeowners, as well as landlords and renters. 

Note: This guide provides a general overview of available rebates for single-family homes. Rebate amounts and eligibility vary for apartment buildings, multi-unit buildings, and multifamily units, and enhanced rebates may be available for income-qualified households.

What Upgrades Are Eligible? 


Proper weatherization is a crucial first step in any home heating or cooling project. Without it, homeowners miss out on the benefits of energy-saving upgrades. By weatherizing your home, you can prevent heated or cooled air from escaping, leading to significant cost savings on your electricity bill. 

Here’s how folks in Massachusetts can save on weatherization through the Mass Save program: 

  • Start with a no-cost home energy assessment to determine your home’s insulation and air sealing needs.
  • Depending on its results, customers may be eligible for no-cost air sealing and 75-100% off the costs of qualifying insulation upgrades.
  • Save $75 per window replacement on ENERGY STAR® certified windows.

Heat Pumps

What is the most efficient heating system in Massachusetts? Why, heat pumps, of course! Heat pumps and mini-split heat pumps are energy-efficient systems that can both heat and cool your home—and, since they’re powered by electricity, they help reduce your household’s carbon footprint. Mass Save offers rebates for both ground-source heat pumps and air-source heat pumps. Here’s what MA residents need to know: 

Whole Home Rebates: 

If you’re considering installing heat pumps as the main heating and cooling source for your entire home, you’re eligible for Whole Home Rebates (exceptions apply for multi-family homes).

  • Single-family homes can receive up to $10,000 in rebates for air-source heat pumps and $15,000 for ground-source heat pumps.
  • You must be a customer of National Grid, Eversource, Berkshire Gas, Cape Light Compact, Liberty, or Unitil.
  • First, you need to meet the necessary weatherization requirements.
  • You must install a heat pump as the only way to cool and heat your home.

Partial Home Rebates: 

If you’re considering installing a heat pump system to supplement your existing boiler or furnace or to heat/cool a specific section of your home, you qualify for Partial Home Rebates.

  • Single-family homes can receive up to $10,000 for air-source heat pumps and $15,000 for ground-source heat pumps.
  • Multi-family homes (5+ unit buildings) receive $1,250 per ton for heat pump systems.
  • You must be a customer of National Grid, Eversource, or Unitil.
  • You can either add the heat pump to your existing heating system or use it for a small section of your home. 
  • Rebates are based on the size (tonnage) of the equipment.
  • If you meet weatherization requirements, you may qualify for an additional $500 bonus.
