  • A Mass Save® energy audit in Waltham may use advanced diagnostic equipment to measure air leakage, assess insulation quality, and evaluate your HVAC system’s performance. This analysis produces a customized report with recommendations tailored to your home’s unique characteristics, whether you’re dealing with drafty windows in Warrendale or inadequate insulation in Cedarwood.

Eligibility for incentives 

Completing the Mass Save® energy audit is the first step to unlocking rebates and incentives for energy-efficient products and services. Without this initial evaluation, you cannot access many substantial savings available to Massachusetts residents.

Personalized recommendations 

An experienced specialist conducts a thorough walk-through to identify specific areas for energy-saving improvements. You receive recommendations tailored to your home conditions, lifestyle, and budget, rather than generic online calculators.

My actress name is Jonelle,and I am also married and my married last name is Berkley. Two young men by the names of Pete and BIG J came over and did the work on my bathroom sink .The pipe under the sink broke and was leaking very badly.It as an emergency call to the Go Endless Energy Company. The two young and very experienced men did an excellent job repairing the bathroom sink! They put in new pipe and faucets and sink stopper. Plus they gave me a one year warranty on all parts and services. I give these two guys that came over today a million plus star's for a job well done. If you call this company for a repair please ask them to send over Pete and BIG J. They are GREAT!!! Thankyou, Mrs.Jonelle A. Ference-Berkley
Friendly, considerate workers. They worked quickly and fixed my shower leak and left the place tidy. Also they inspected other items in my house and gave me estimates for future work they recommend .
Very nice team!
Eydin was very professional and helpful.
Marcus did a great job and gave us detailed information after our energy assessment. Helpful and very knowledgeable. Recommended.
Response from the owner:Hi Jim, thank you for the kind words about your Mass Save Home Energy Assessment and trusting us!
I called Endless Energy to ask for a quote for some plumbing work and everyone I spoke to on the phone was kind, professional and efficient. Josh and Peter came out exactly at the time they were scheduled and were polite and professional. Josh was extremely knowledgeable and spent time understanding my plumbing concerns and explaining everything to me and detailing the process for completing the repairs. He sent me a detailed quote and gave me a timeline for getting the parts needed. Josh and Peter came out for the repairs right on time and did an excellent job. They made sure everything was working perfectly and cleaned up once repairs were completed. I could not recommend them more!
Response from the owner:Thank you so much for your kind words. We're glad our expert plumbing team was able to assist you with your repairs and that our team was responsive. If you need anything else, please let us know!
Just a Wonderful Company that installed a Heat Pump with two Splits.
In addition, Technician Eydin Gomez has been to my home twice recently and has performed exceptional work in making my Oil Burner and Heat Pump perform very well.
I appreciate his hard work and expertise.
Response from the owner:Thank you so much for your kind words, Bob! We’re thrilled to hear you had a wonderful experience with Endless Energy. It's fantastic that you’re enjoying your new heat pump system. Your satisfaction means everything to us! If you ever need assistance, please reach out.
Brad, the account manager, was timely in responding to my many questions and sending quotes to match my requests. Very courteous, professional, organized implementation crew led by Hunter and his helper Shameel and the rest of the crew that came on day 2. This included moving, without complaint, the location of one of the units which made me very happy.

Update: CJ came to provide annual maintenance in April 2026. He was polite and tidy in his work. Also, he was patient with my repeated questions about ice that had built up on the unit over the winter (which turns out is not a problem).
Response from the owner:Ellen, thank you so much for your kind words and for taking the time to share your experience with Endless Energy! We're thrilled to hear that Brad was able to assist you promptly and professionally, and that Hunter, Shameel, and the rest of the crew exceeded your expectations during the installation.

It’s great to know that the team was able to accommodate your request to move the unit and that it brought you satisfaction. Our goal is always to ensure that our customers are happy with both the process and the final results.

If you need anything else in the future or have any more questions, please don’t hesitate to reach out. We’re here to help!
I got a MassSave inspection. It was great, what was being checked and the suggestions were all all described to me very clearly.
