Why You Need a Home Energy Assessment
There are many ways to make your Massachusetts home more energy efficient. At Endless Energy, we can identify them. We’ll also help you access rebates and other financial incentives through the Mass Save® Program.
Your no-cost assessment can not only qualify you for a heat pump rebate (we’re part of the Mass Save® Heat Pump Installer Network). It can also help find other options to reduce energy usage. This means a chance to save with financial incentives, including instant rebates, and lower utility costs!
Inspection:
A detailed inspection of your home, its insulation, and where heat loss and other inefficiencies are occurring.
Recommendations:
Our team will provide customized recommendations based on their findings.
Access to Financial Savings:
We’ll inform you of all available incentives that make insulation and other upgrades more affordable.
Here’s a more detailed look at our process:
When we complete your Home Energy Assessment, you’ll also receive an in-depth report with all the fine details about your home’s energy efficiency.

We had an energy assessment with Seth, and it was a great experience. He provided us with several no cost upgrades (power strips, showerheads, etc.) and recommended some insulation work at a very reasonable price due to the Mass Saves incentives.

Endless Energy did necessary repairs, etc., to improve whole house heat retention, following an earlier no cost energy inspection. Todd was exceptional with his explanations. All work was done well and rapidly. I highly recommend this team.
Patti D.
Endless Energy performed a Mass Save energy audit and insulation upgrade for our house. All personnel were very friendly and professional. They arrived on time and worked continuously to do the install. They also applied the substantial Mass Save incentives to the cost of the job. All good stuff!

Endless Energy's team, led by project manager Ryan, did a great job insulating our attic and basement. They worked efficiently, were neat, and patiently answered my questions. They also took care of a few extra small in-scope tasks I requested, and did a great job with cleanup.
Neal M.
I recently worked with Endless Energy on an insulation project in our attic to reduce what we were spending on electricity and oil. The crew was hardworking, polite, and focused on the work that needed to be done.
George B.
Endless Energy recently completed a massive insulation project at my home in Framingham, totaling over 4,000 square feet of attic, wall, and crawl space insulation. The technicians, Todd, Carlos, and Stephen, were incredibly professional and knowledgeable. They worked diligently for almost two weeks. They were punctual, respectful, and maintained a tidy workspace throughout the entire project.

I could not be more pleased with the service I received from Endless Energy. Alycia Maxwell was in constant communication with setting up appointments to accommodate my schedule. The team that showed up was very polite and kind. They left the room cleaner than when they arrived.

It was such a blessing to work with Endless Energy. They were communicative, scheduling was a breeze, and everything was taken care of without having to worry. The workers were professional and kind. All of the work was done on time, and they explained everything at every step.
Stacie B.
During the process, all your representatives proved time and time again that you were looking out for my best interests. However, I would like to give specific recognition to the install team leader and his assistant. They were incredible to work with. They took the time to explain everything to me and left their work area cleaner than when they found it.
Stacie B.
The employees of Endless Energy are always kind, punctual, and knowledgeable. They are thorough in their inspection and good at communicating their needs to fully inspect the house. Their follow-up is detailed and helpful in making decisions.

These guys were great; they did a great job and were fast, efficient, and friendly! You could feel the difference in the house immediately! I would recommend them highly. Looking forward to saving money on my electric and my oil! Thank you so much, Endless Energy and my representative, Dan.

Benefits of Improved Insulation
At Endless Energy, we know every home is unique. We provide a solution tailored to your needs, so you see all the great benefits of proper insulation:
Consistent Temperature:
Updating your home’s insulation can eliminate drafts and variations in indoor temperatures.
Lower Energy Costs:
High-quality insulation can help reduce your monthly utility costs year-round.
Increased Property Value:
Potential buyers can see a well-insulated home as more attractive and be willing to pay a higher price for it.
Sustainability:
Insulation improves energy efficiency, which reduces your home’s carbon footprint and environmental impact.
Reduced Noise:
Insulation can absorb sound, so it reduces noise from outside and other rooms in your home.
Enhance Your Home’s Comfort and Efficiency with an Insulation Upgrade
Attic Insulation:
Attics are major sources of heat loss and heat gain; insulating your attic is beneficial in the winter and summer.
Wall Insulation:
Our team uses the latest, most advanced techniques to create an effective thermal barrier.
Crawl Space Insulation:
Homeowners don’t often consider the crawl space as a source of energy loss, but insulating it improves overall efficiency.
Thanks to the partnership between Endless Energy and Mass Save®, you can potentially save thousands of dollars upfront. Our insulation installation professionals are experienced with all common materials. They help choose the right type and thickness, which depends on the area being insulated.
