Jeffrey Riklin
I had a MASSAVE audit with Mike Heil. He is a true professional. Not only is he knowledgeable about the process, energy audit, and programs, but he is a pleasant and enjoyable person. They are lucky to have him as the face of the company!
Response from the owner:Thank you for taking the time to leave your fantastic review! We couldn't agree more that Mike is great asset on our team!
Scott Nevins
CJ was really efficient and helpful with our needed repair. Gave us honest feedback and recommendations.
Response from the owner:Thank you so much for the fantastic 5-star review, Scott! We're thrilled to hear that CJ provided you with efficient service and honest recommendations. Your satisfaction is our top priority at Endless Energy, and we appreciate your kind words!
Marc Chamblee
Technicians have always been courteous and knowledgeable about the HVAC system. The most recent service technician, James, was fantastic. He was worked efficiently and offered thorough explanations of the work that needed to be performed.

I have, unfortunately, over the course of the last 3 years had to interact with Endless Energy representatives all too often, because the system they installed has had an array of issues. While the repairs and adjustments have been costly and the continuing issues with the dusting have been frustrating, I can say that I have no complaints about the individual service technicians who work for the company.
Response from the owner:Thank you so much for your thoughtful review, Marc! We're thrilled to hear that our technicians, especially James, provided courteous and knowledgeable service during your HVAC maintenance. It's great to know that their efficiency and thorough explanations made a positive impact. We're genuinely sorry to learn about the ongoing issues you've faced with your equipment. Your feedback is invaluable, and we appreciate you as a valued customer and will continue to partner with you to ensure your system is working properly. Thank you for taking the time out of your day to send positive feedback about our technicians, especially given your challenging experience.

Nancy Auerbach
Endless Energy just did the annual maintenance on our Mitsubishi heat pump, and I wanted to take a moment to compliment their technician, Eydin. Eydin was friendly, efficient and highly professional, and we appreciated the thoroughness with which he serviced our system. He went out of his way to make sure we were happy, and he patiently answered all of our questions. Highly recommend!
Response from the owner:Thank you Nancy for your kind review! We will be sure to extend your praise to your technician!
Paul Kelly
Eydin and Ryan did a great job. Under warranty, they repitched the air handler in our attic so that condensation flows to the drain appropiately. They were prompt, professional, and explained clearly what they were doing and why.
Response from the owner:Thank you so much for your kind words! We're thrilled to hear that Eydin and Ryan provided you with prompt and professional service. Your satisfaction is our top priority, and we're glad we could resolve the issue with your air handler effectively.
Jose Kleinberg
We had HVAC maintenance service and were extremely pleased by Mike and Travis’ workmanship: meticulous cleaning and care, respectful attitude toward the home, leaving no mess behind, courteous and friendly attitude and willingness to explain the process and answer any questions.
