Why Endless Energy

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!

Here’s a more detailed look at our process:

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.

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 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.

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.

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.

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.
