Sue Livermore

Hunter and his team (Cameron and Pedro) were pleasant, unfailingly polite, professional, hardworking, and efficient. Hunter was very accommodating and patient with our questions and concerns. He was especially good at leading his team and explaining what needed to be done. The equipment was installed neatly, and the quality is top-notch. He and his crew were respectful of our property and gardens. They cleaned up when they were finished, and Hunter carefully explained the operation of the system to us. The job was finished on time and with a minimum of fuss. Hunter is a great ambassador for Endless Energy. He deserves a five-star rating.

Mark Otis performed our Mass Save Home energy assessment. He is yet another example of the professionalism and quality of the people employed by Endless Energy. He was friendly and polite, and he listened to our questions and concerns. He thoroughly examined our house and quickly identified what was not insulated and what required more insulation. He performed a combustion safety test on our boiler and then crawled out into the attic space under our eaves on a hot day to be sure of what he was dealing with. He laid out our alternatives clearly and produced a comprehensive set of reports and documents on the same day. We’d be happy to refer Mark to our family and friends. Five starts for Mark.

Our AC is back! Thanks to Eydin of Endless Energy who patiently worked on the repair for 5 hours, working outside that day is very uncomfortable, 84F, but besides that he was able to finish the job effectively and on a timely manner. I can tell based on our conversation that he is knowledgeable for the task and very efficient. He gave me detailed answers to my questions. Eydin is very polite and professional. Very satisfied customer here, Endless Energy highly recommended. Thank you!

I am installing solar and National Grid is making me either curtail my power export or install batteries or pay them $8000 to upgrade their transformer, so I picked the batteries. Unfortunately, the duct work for my heat pumps was set too close to the only wall in the house where the batteries can go and had to be moved. The solar project was stopped until the batteries passed inspection. Eydin made time in his schedule to move 12' of ductwork 30" over on a Saturday so I can pass my electrical inspection. My sincere thanks to Endless Energy and especially Eydin! I can't wait to turn on the solar and say goodbye to sky-high electric bills from National Grid!

Eydin came to check out my HVAC system that was not working properly. He was very knowledgeable about systems in place and gave helpful tips. He also switched our filters out which was a great help.
