Eydin was very professional and helpful.

Jim Feeney

Marcus did a great job and gave us detailed information after our energy assessment. Helpful and very knowledgeable. Recommended.

N Hernandez

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!

Bob Green- Providence College

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.

Ellen Stewart

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!

Eydin and James did our annual AC maintenance and once again they did a great job. They are always on time, very professional in doing the work as well as very informative and pleasant to work with. We highly recommend to whoever needs this service.

Professional HVAC Replacement?

No matter how happy you are with your heating and cooling, your devices have an average lifespan of about 10-15 years. That’s because there’s rapid improvement in the field of HVAC, so newer models are far more energy efficient than older ones. Plus, older systems become less reliable and efficient over time. Let us know if you’re ready to update and upgrade your comfort with a new heating or cooling system! We carry a great selection of quality HVAC systems for any budget and any home. Whether you need a new furnace or heat pump we have you covered!

Don’t Neglect Your Annual Tune-Up

We recommend that all of our customers book an annual tune-up service. Although this appointment doesn’t take long, it can net you some major savings throughout the year. First of all, as your technician cleans and lubricates all relevant parts, they ensure that your system will be operating at maximum efficiency all year.

On top of that, our talented technician will inspect your HVAC equipment and let you know if you need to get any repair work done — which of course means that you’ll be unlikely to encounter any problems with your HVAC system.
