How to Get Free Energy Upgrades in Massachusetts (2026 Guide)

Massachusetts homeowners are leaving thousands of dollars on the table. In 2026, the Mass Save energy efficiency program is offering free and heavily subsidized energy upgrades — including insulation, weatherization, heat pumps, and smart thermostats — to qualifying residents across the state. If you pay an Eversource, National Grid, or Unitil utility bill, you are already funding this program and eligible to claim your benefits. Getting free energy upgrades in Massachusetts is a straightforward process: schedule a no-cost home energy assessment, receive your personalized upgrade recommendations, and let Mass Save-approved contractors complete the work — often at zero out-of-pocket cost. Here is exactly how to do it.

• Schedule a free Mass Save Home Energy Assessment to get started.
• Qualify for free insulation and air sealing (up to 100% for income-eligible households).
• Receive free smart thermostats through your utility provider.
• Access 0% interest financing on qualifying energy upgrades.
• Get rebates on heat pumps, heat pump water heaters, and HVAC systems.
• Income-eligible homeowners can receive upgrades at no cost through Mass Save LEAN.
• Renters and landlords both qualify for select Mass Save programs.
• Combine Mass Save rebates with state and federal tax credits for maximum savings.

What Is Mass Save — and Why Should Massachusetts Homeowners Care in 2026?

Mass Save is a statewide energy efficiency program administered by Massachusetts’ major electric and gas utilities — including Eversource, National Grid, and Unitil — in partnership with the Massachusetts Department of Energy Resources (DOER). The program is funded through a small charge already built into your monthly utility bill, which means you’ve almost certainly been paying into it for years without ever claiming your benefits.

The goal of Mass Save is straightforward: help Massachusetts homeowners reduce energy consumption, lower utility bills, and improve home comfort. In practice, that means covering the cost of insulation, weatherization, smart thermostats, heat pumps, and more — often at no cost to you, or at dramatically reduced prices through rebates and 0% financing.

With Massachusetts winters being as brutal as they are — think sub-zero wind chills in Worcester, feet of snow in Springfield, and relentless cold from November through March — the demand for these upgrades has never been higher. And in 2026, program funding is robust. The window to act is open. The question is: are you taking advantage of it?
