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!
