There are many benefits that an energy-efficient home can provide, such as lowering your carbon footprint and saving money on energy costs. The Mass Save® program makes it easy for eligible homeowners, renters, landlords, small business owners, and property owners to make the upgrades necessary to make their homes and buildings more energy efficient. If you’re a Massachusetts resident, you have probably heard about the benefits of the Mass Save program and the generous incentives available to locals like you.

Advanced Power Strip

Household items like computers and coffee makers continue to draw power even when they’re in the off position. The National Renewable Energy Laboratory (NREL) says that vampire loads add approximately $200 every year to your energy costs at home and wastes energy that could’ve powered 11 million homes. Get advanced power strips at no-cost through a Mass Save Home Energy Assessment.

Business Assessment

The Mass Save program offers no-cost assessments to small businesses in Massachusetts to help find savings opportunities that will allow owners to save money on overhead costs and increase comfort for employees and customers. There is a 100% off insulation offer that is running right now for a limited time. Go here to schedule a small business assessment.

Carbon Emissions

The Mass Save program was created by Massachusetts utilities and energy efficiency service provider to lead the state to a cleaner future and help residents save energy and money. Massachusetts continues to be one of the most efficient states in the country, ranking #1 or #2 for more than a decade, according to the American Council for an Energy-Efficient Economy (ACEEE). The Mass Save program is an integral part to meeting the state’s goals of zero emissions by 2050.

Ductless Mini-Split

Through the Mass Save program, you can access up to $10,000 in rebates for ductless heat pump systems. Ductless mini-split (DMS) systems are great if you have a non-ducted heating system, want to heat/cool an addition without ductwork, or want to condition individual rooms to your liking. Learn more about ductless mini-splits here and read in-depth about electrification here.

Energy Assessment

The Sponsors of Mass Save offer Home Energy Assessments at no cost to Massachusetts residents. A Home Energy Specialist will come to your home to show you how your home consumes and loses energy. An assessment typically takes about 2-3 hours and you get a custom home energy report at the end with details about saving opportunities and eligible Mass Save rebates. You can walk around your home with your Specialist and they’ll explain everything they’re doing.


Participation in the Mass Save program is no cost because residents like you help fund the program with a small energy efficiency charge on your utility bill. Take a look; you’ll see the charge! We get the frequent question about why the incentives are available and why there’s no charge for things like air sealing and assessments, and this is why!

Generous Incentives

To make your home more energy efficient, the Sponsors of the Mass Save program offer incentives like 75-100% off insulation, 100% off air sealing, up to $10,000 in heat pump rebates, 0% financing for energy efficiency upgrades, no-cost energy-saving items, and more. To access the incentives offered to eligible Massachusetts residents, you must first get your home assessed at no cost.

Heat Pump Rebates

A heat pump is an extremely efficient way to heat and cool your home, all with one system, powered by electricity. While there are different kinds of heat pumps on the market, an air-source heat pump (ASHP) is the most common one installed in New England. A heat pump transfers heat from one place to another, which is what makes it so efficient – it requires less energy to transfer heat than to generate it. The Mass Save Sponsors have rebates up to $10,000 for heat pumps! Learn in-depth about heat pumps and electrification here.

Insulation Incentives

According to ENERGY STAR, 9 out of 10 homes don’t have enough insulation. Insulation acts as a winter sweater for your home, working to keep your home warm or cool! That’s right, you also feel the benefits of insulation during the summer. Insulation protects you and your family all year long. Through the Mass Save program, you can access 75-100% off recommended insulation upgrades. You can get your current insulation levels assessed at no cost by signing up for an assessment here.

Job Programs

The Mass Save Clean Energy Pathways program was created to develop HVAC skills and boost the energy efficiency workforce. It’s a paid internship program that lasts for three months, which could turn into full-time employment with the company afterwards. HomeWorks Energy is one of the companies partnering with the Mass Sponsors on this project and we are hiring interns.

Keep Air Outside

If insulation is your home’s winter sweater, consider air sealing its windbreaker. Sealing the gaps, cracks, and holes in your home keeps the heat where it belongs – outside during summer and inside during winter! The Natural Resources Defense Council (NRDC) says that if you add up all the holes in a typical home, where air is leaking, it’s equivalent to leaving one window open all year long! Luckily there is an easy solution because Massachusetts residents can get 100% off air sealing through the Mass Save program.

Low-Income Program

The Sponsors of Mass Save believe energy efficiency is for everyone. If you qualify for the income eligible program, you could receive increased offers like no-cost insulation and new appliances like heating systems and refrigerators. For example, income for one person would have to fall under $42,411 and an income for a 4-person household under $81, 561. For more information or to look at other income levels, click here.

Money Saved

Making your home more energy efficient means more money in your wallet! To read about real homeowners and their real savings, click here. For example, one Westhampton homeowner is expected to save almost $500 every year with the energy upgrades that were made to their home. Many upgrades pay for themselves such as insulation, in a couple years or less.

No-Cost Items

When you get a no-cost assessment through the Mass Save program, you get items installed in your home such as advanced power strips, faucet aerators, water-saving showerheads, and programmable thermostats. These items are called “instant savings measures” because you start saving energy and money the minute you start using them! Once your assessment is over, you get your items right there – there’s no waiting!

Offers for Renters and Landlords

According to the Mass Save Sponsors, every $1 spent on energy efficiency could add up to $10 in property value. Landlords have access to big incentives such as 100% off insulation to keep energy costs down for their tenants and make their buildings more comfortable. Renters can also sign up for a no-cost assessment of their unit to get the process started.

Programmable Thermostat

No-cost programmable thermostats are offered through a Mass Save Home Energy Assessment. You can program your thermostat with various automatic settings so that you save money while you’re asleep, away at work, or on vacation. According to the U.S. Department of Energy, you could save up to 10% every year on heating and cooling by setting your thermostat back for 8 hours a day, 7-10 degrees. The Mass Save Sponsors also offer a $100 rebate off a smart thermostat.

Quote for Upgrades

After a no-cost Home Energy Assessment, you get detailed numbers! For example, your Home Energy Specialist will walk you through recommended insulation upgrades, what the price of that original project is, what rebates you would be eligible for, and what would be your out-of-pocket cost. They can also discuss financing options for what’s left for you to pay. At HomeWorks, we also offer heat pump consultations at no-cost where we will come to your house and give you an on-the-spot quote for a system that’s designed specifically for your home.

Refrigerator Recycling

If you have a working refrigerator or freezer that’s not energy efficient, you can recycle them through the Mass Save appliance recycling program. The program offers no-cost pickup and removal, plus a $125 rebate to go toward your next eco-friendly refrigerator or freezer. To qualify, you must be an electric account holder of Eversource, National Grid, Unitil, or Cape Light Compact. For more information, click here. This is a limited-time offer as the rebate typically offered is $75.

Safety Check

A Home Energy Assessment includes elements of safety such as a combustion safety test. A combustion safety test is performed during your assessment to verify that all combustible appliances are working properly and are vented as they should be to protect you and your family. This test is performed to verify that gases are not being trapped inside your home. For example, if a gas dryer is not appropriately vented, carbon monoxide could build up in your living areas and cause severe consequences.

Three-Year Plan

The Three-Year Energy Efficiency Plan was developed by the Program Administrators (such as Eversource, Cape Light Compact, and National Grid) to support the Commonwealth’s goal of net zero emissions by 2050. The foci include electrification, equity, and workforce development. Participation from Massachusetts residents like you contributes to the GHG emission reduction goals and more.

The Sponsors of the Mass Save program include your local electric and natural gas utilities and energy efficiency service provider: Berkshire Gas, Cape Light Compact, Eversource, Liberty Utilities, National Grid, and Unitil. They have official partners, like HomeWorks Energy.


R-value is a measurement of how well insulation resists the conductive flow of heat. The higher the R-value, the better that material is at insulating your home. In many parts of the U.S., homes can get away with lower R-values because of the climate, while other areas of the country will need more protection. To see the recommended R-values for your area of the country, click here to see an ENERGY STAR map. At a Mass Save assessment, your specialist will ensure that you have the proper insulation for the best protection of your home and family.


When you upgrade a single-pane window to a triple-pane ENERGY STAR-certified window, you can get a $75 rebate through the Mass Save program. According to Mass Save, the upgrade could reduce energy costs and your home’s carbon footprint by 12%. You could expect a yearly savings of $101-$583. To qualify for the rebate, you must complete the weatherization recommendations provided during your assessment. For more information, click here.
