The technician, JT, provided excellent detailed maintenance and cleaning of my two Fujitsu units and my two Mitsubishi units. He noticed one of the Fujitsu heads had accumulated a large amount of mold buildup. Thankfully, he scheduled June 18th as the date for him or another technician to return to clean this mini split head.

6/18/25
One of my Fujitsu mini-splits had a great deal of mold buildup. Eydin, the technician, explained what he would have to do and did an excellent job of answering my questions and cleaning the mini split head.

Both technicians were very knowledgeable about the mini splits, the work that needed to be done, answered all my questions and completed everything in a timely fashion.

I have been a customer of Endless Energy since 2018 and have dealt with them multiple times for various tasks. They have always provided excellent service and superb after-sales service. Most recently I got an energy assessment done by them. Mark Otis came in on time, was extremely knowledgeable, very courteous and provided very helpful feedback. Best of all, he did not try and upsell me anything and left me with important and helpful information I could use in the near future. A truly comfortable experience and I would highly recommend them for all your energy savings needs.

I’d recommend Endless Energy 10/10, they were punctual, transparent, & worked diligently! They weren’t able to finish the job in one day due to unforeseen circumstances. However, they came back the next morning & finished the installation of HVAC system.
Hunter, Mike, & Keith were very professional!
Hunter explained the process of what was going to happen & what to expect, which was appreciated!!

Special thanks to Don Davis and Cameron Nolette for their thorough annual maintenance on our LG heat pump. Above and beyond the call ensuring condensation water drained properly - completely ready for the summer. Many thanks.

Gavin arrived on time and did an excellent job in fixing our HVAC system! He was very professional in troubleshooting and fixing the issue, and verified with our smart thermostat that everything was configured properly and working as expected.

Exceptional service from Eydin Gomez, very professional and knowledgeable.

Peter from Newton

Daniel Hagerstrom of Endless Energy completed a MassSave-sponsored energy audit of our house in Newton. We are considering heat pump installation and asked that he focus on how heat pumps would fit with our heating and cooling needs. He was very helpful in furthering our education on options and factors affecting those options. Dan also reviewed our existing insulation and recommended further wall insulation. He is very knowledgeable and professional. We recommend him if you are considering a home energy audit.
