They came out to check on my compressor they installed this fall after it sustained some damage from falling snow and ice. CJ was probably the nicest service person I have ever had come through my house. He thoroughly inspected the compressor and my units, and then took the time to research a snow guard for me to install for future winters.

The first year maintenance by Eydin was great.

Knowledgeable staff. Came right on time. Happy with the service.

I am one of the few that do take reviews very serious, if I give you 1 you deserve a 1 and if I give you a 5 you definitely deserve a 5. I got my system installed in October and had a manufacture defect in February. Miscommunication took place between the company and I and it got to the owner he reached out out to me after hours 11:30pm apologizing and did promised that first thing in the morning I was going to heard from the team to get a time frame which was Monday, I told my husband maybe he only promising me
To calm me down, no he was not by Wednesday his team was up replacing my whole system. I am
Sorry I don’t get the technician names but they work all day making sure I was up and running properly. Thanks to them and the Owner Matt. He do value his customers and listen to their cry. As a business owner myself that was a top notch for me. Definitely will be sending more customers your way. Thank you endless energy

Garrett did an excellent job servicing our heat pump. He was extremely knowledgeable and took the time to explain everything clearly, making sure I understood what was going on and what to expect moving forward. His professionalism and attention to detail really stood out. It’s refreshing to work with someone who not only knows their craft but is also great at communicating it. Highly recommend Garrett for anyone needing HVAC service.

I had an energy assessment done at my home in Winchester by Endless Energy, and the experience was outstanding — especially thanks to Brendan.

Brendan was extremely thorough, professional, and detail-oriented. He carefully inspected every area of the house and took the time to clearly explain the current energy efficiency conditions, potential issues, and recommended improvements.

I truly appreciated his patience in answering all of my questions. His explanations about insulation, air sealing, and energy savings options were very informative and helpful for planning future upgrades.

If you are considering insulation or any energy efficiency improvements, I highly recommend requesting Brendan from Endless Energy. The service was knowledgeable, honest, and genuinely customer-focused.

We installed a high-efficiency boiler about ten years ago but the company went out of business immediately afterwards. We have been looking for someone to service it, but the plumbers who saw it seemed to have no idea how to deal with it; turns out it is not a common home-type boiler. I searched high and low for a knowledgable person to help with this, and Donald at Endless Energy was the guy. He quickly identified the problem, which was that our boiler was a fancy (who knew!) early model of a high efficiency home boiler, which did not find a broad market at the time, not until it was redesigned and lowered in price. So most plumbers had never seen it. Donald's deep experience with boilers of all sorts, and his interest in the industry, enabled him to do the maintenance quickly and efficiently.We were extremely impressed with his really smart assessment of the situation, his professionalism, and his thoroughness. This was by far our best experience with a home repair in 35 years.
