Program Overview
What is Mass Save®?
Mass Save® is a collaborative initiative by Massachusetts' electric and natural gas utilities that promotes energy efficiency services for residents, renters, landlords, and businesses. The program offers no-cost home energy assessments, substantial rebates, and zero-interest financing to help reduce energy consumption and lower utility bills.
Participating Utilities: Eversource, National Grid, Unitil, Berkshire Gas, Cape Light Compact, and Liberty Utilities
Who funds Mass Save®?
Mass Save® is funded through energy efficiency charges that appear on customers' monthly gas and electric bills. These small charges, which Massachusetts residents already pay, fund the no-cost assessments, rebates, and incentives offered through the program. Essentially, you've already contributed to funding these benefits.
Who qualifies for Mass Save® programs?
Massachusetts homeowners, renters, landlords, and businesses who are customers of participating utility companies qualify for various Mass Save® programs. Some rebates may have additional requirements based on household income, property type, or previous participation in energy efficiency programs.
How long has Mass Save® been around?
Mass Save® was launched in 2009 as part of Massachusetts' commitment to energy efficiency and carbon reduction. The program has evolved over the years, expanding rebates, adding new technologies like heat pumps, and introducing innovative financing options like the zero-interest HEAT Loan.
Home Energy Assessments
What is a Mass Save® Home Energy Assessment?
A comprehensive evaluation of your home's energy efficiency conducted by BPI-certified professionals. The assessment identifies energy-saving opportunities, provides personalized upgrade recommendations, and determines your eligibility for rebates and incentives. The process includes blower-door testing, thermal imaging, and installation of immediate energy-saving products.
How much does a home energy assessment cost?
The comprehensive home energy assessment is completely no cost for eligible Massachusetts residents. The assessment is funded by energy efficiency charges that you already pay on your utility bills, so there's no additional cost to schedule and receive this valuable service.
How long does an assessment take?
A typical home energy assessment takes 90-120 minutes for most single-family homes. Larger homes or properties with complex systems may require additional time. The assessment includes exterior and interior evaluation, testing, installation of energy-saving products, and a detailed review of findings and recommendations.
What do I receive during the assessment?
During your assessment, you'll receive no cost installation of immediate energy-saving products, including:
- • Energy-efficient LED light bulbs
- • Low-flow showerheads and faucet aerators
- • Weather-stripping for doors and windows
- • Smart power strips to reduce phantom loads
- • Programmable thermostat (when applicable)
Can renters get assessments?
Yes! Renters can access online energy assessments without landlord permission. For in-person assessments with major upgrade opportunities, landlord cooperation is beneficial but we can help you approach property owners with information about available rebates and the value of energy efficiency improvements.

However, there are substantial incentives for transitioning to electric heat pumps, which can provide both heating and cooling while significantly reducing energy costs.
Can I combine Mass Save® rebates with federal tax credits?
Yes! Mass Save® rebates can often be combined with federal tax credits, state incentives, and utility-specific programs to maximize your total savings. For example, heat pump installations may qualify for both Mass Save® rebates and federal tax credits of up to 30% of the project cost.
How are rebates processed and paid?
Rebates are typically processed as instant discounts at the time of installation when you work with Mass Save® participating contractors like Econova. We handle all rebate paperwork and applications, so you see the reduced price immediately rather than waiting for reimbursement checks.
Eligibility Requirements
What makes a home eligible for Mass Save® programs?
To qualify for Mass Save® residential programs, you must meet these basic requirements:
- • Be a customer of a participating Massachusetts utility
- • Live in a one to four-unit residential property
- • Have not received similar energy upgrades recently
- • Complete a home energy assessment before rebate eligibility
Are income limits required for Mass Save® rebates?
Most Mass Save® rebates are available to all eligible customers regardless of income. However, some enhanced rebates and additional programs may have income qualifications that provide even greater savings for low-to-moderate income households. We can help determine all programs you qualify for during your assessment.
Can I participate if I've had energy work done before?
Previous participation in energy efficiency programs may affect eligibility for certain rebates, but doesn't disqualify you entirely. We review your home's history during the assessment and identify any remaining qualifying improvements. Many homes can benefit from multiple phases of efficiency upgrades over time.
Do condos and townhomes qualify?
Yes, many condos and townhomes qualify for Mass Save® programs, though the specific improvements available may vary based on what systems you control versus what the condo association manages. We can evaluate your specific situation and identify eligible improvements during the assessment.
Financing Options
What is the HEAT Loan program?
The HEAT (Home Energy Assessment and Transformation) Loan provides up to $25,000 in zero-interest financing for qualifying energy efficiency improvements. This innovative program allows you to finance the remaining costs after rebates with no interest charges, making comprehensive energy upgrades accessible to more homeowners.
Is the 0% interest rate permanent?
Yes, the HEAT Loan offers true 0% interest for the entire loan term. There are no introductory rates, promotional periods, or interest rate increases over time. You pay back exactly what you borrow with no additional interest charges.
What credit score is needed for HEAT Loan approval?
Credit requirements vary by participating lender, but the HEAT Loan program is designed to be accessible to homeowners with fair to excellent credit. The exact requirements depend on the lender, loan amount, and other factors. We can help you understand your options during the assessment process.
Are there other financing options available?
Beyond the HEAT Loan, many contractors offer additional financing options for energy efficiency improvements. These may include traditional loans, equipment financing, or lease programs. We can help you compare all available options to find the best solution for your budget and project needs.
