Start at MassSave.com/WindowQPL and use the Filter Your Results tool to select windows certified for the Northern Region. Look for windows on the 2024 Most Efficient list, which now allows a wider range beyond triple-pane models. Confirm the presence of the NFRC label, showing compatibility with your climate zone. Before installation, an Energy Specialist will verify your windows during a no-cost energy assessment. Only ENERGY STAR Most Efficient certified windows qualify for Mass Save rebates when replacing single-pane windows.

To successfully claim your rebate, follow these steps:

Your home can expect savings ranging from $101 to $583 annually from replacing single-pane windows and benefiting from the Mass Save offer.
Financing and HEAT Loan Options for Homeowners
Replacing your windows with ENERGY STAR Most Efficient models can lead to substantial energy savings, but financing that window replacement through the Mass Save HEAT Loan isn’t an option since the program doesn’t cover windows.
However, you can still use the HEAT Loan to finance other energy efficiency upgrades like insulation, ductless mini-split heat pumps, or high-efficiency water heaters, which help reduce energy consumption.
To maximize savings, combine this financing with rebates and investigate federal tax credits for energy-efficient windows. This strategic approach makes upgrading more affordable while lowering utility bills and carbon footprint.
Complementary Energy Efficiency Upgrades: Insulation and Air Sealing
Because insulation and air sealing directly address heat loss and drafts, they’re essential energy efficiency upgrades that work hand in hand with window replacement to maximize your home’s comfort and reduce heating and cooling costs.
The Mass Save Program requires you to complete these upgrades to qualify for window replacement rebates.
Here’s why you should prioritize insulation and air sealing alongside window upgrades:
- Cut energy bills by up to 15% through reduced heat loss
- Eliminate drafts for improved indoor comfort
- Improve overall energy efficiency when combined with window upgrades
- Contribute to lower greenhouse gas emissions from your home
- Fulfill Mass Save Program requirements for rebate eligibility
Integrating these complementary upgrades boosts your investment’s impact on energy savings.
Benefits of a Home Energy Assessment
Identifying energy inefficiencies through a no-cost Home Energy Assessment gives you a clear picture of where your home loses energy and where improvements will have the greatest impact.
This assessment helps you reduce energy waste by targeting upgrades like insulation, air sealing, and energy-efficient windows.
Through personalized recommendations, you can increase comfort while achieving up to 15% annual savings on energy bills.
Plus, completing the assessment is required to qualify for Mass Save rebates and incentives, making it a strategic step to maximize your financial benefits and create a more energy efficient home.
Leveraging Federal Tax Credits With Mass Save Rebates
You can maximize your savings on window replacements by combining the federal tax credit—worth 30% of project costs up to $600 annually—with Mass Save rebates of $75 per qualifying window.
To do this, choose ENERGY STAR Most Efficient certified windows that meet both federal and Mass Save eligibility requirements.
Make sure to keep all purchase and installation documents to claim both incentives properly and reduce your overall costs effectively.
Federal Tax Credit Benefits
Federal tax credits and Mass Save rebates form a powerful combination to reduce the cost of upgrading to energy-efficient windows in Massachusetts.
By leveraging both, you maximize financial benefits while boosting home energy savings. Consider these critical points:
- The federal tax credit covers 30% of eligible window replacement costs, up to $600 annually.
- Mass Save rebates offer $75 per window for replacing single-pane windows with ENERGY STAR Most Efficient certified windows.
- You may claim the federal tax credit even if you don’t qualify for Mass Save rebates.
- Combined incentives can yield annual energy savings from $101 to $583.
- These programs make energy-efficient upgrades more affordable and accessible for Massachusetts homeowners.
Combining Rebates and Credits
Although the federal Energy Efficient Home Improvement tax credit and Mass Save rebates operate independently, you can utilize both to substantially reduce your window replacement costs.
By choosing ENERGY STAR Most Efficient certified windows, you qualify for a $75 rebate from Mass Save plus a federal tax credit worth 30% of eligible expenses, up to $600 annually.
Even if you skip Mass Save, the federal tax credit still applies, giving you flexibility in energy-efficient upgrades.
Combining these incentives significantly lowers upfront costs and contributes to annual energy savings ranging from $101 to $583 on your window replacements.
