Very good experience
After calling several places with two no shows, the moment I called Endless Energy, I felt like I was in good hands. Jake had THE BEST customer service skills and really worked with me to help my situation. This something you don't see that often anymore. My central air cranked out during the heatwave, and he was able to get me an emergency appointment since I have a little girl with complex medical needs who is more compromised in these situations. That same stellar service continued the moment Eydin and Pedro walked through my door to assess and fix the problem. They were pleasant and skilled. They took the time to explain each of the issues, showing me videos of before and after. "Exceptional" service from the first call to completion. 5 Stars and High Five to this Team and your company. You are doing something RIGHT.
Very helpful staff on servicing my 8-year old heat pump unit. The whole house heat pump system they installed 2 year’s ago is working well even though that heat wave we just had.
Easy fix , clear communication, kind and efficient
Mark was very informative and easy to communicate with
I discovered that my central AC unit started leaking water in the basement in the afternoon on 6/24/2025, when it was100 degrees outside. Endless Energy answered my phone close to 5 PM and called me back to confirm my appointment just before 5:30 PM. They were courteous, responsive and reliable.

Eydin arrived in about an hour. He was polite, professional and meticulous. Throughout the process, he explained his diagnosis and solutions he would try. After cleaning the main clogged pipe, he carefully examined the other parts of the central air unit to see if they were leaking. He also gave me advice on getting fans to dry the floor.

I appreciate Endless Energy for their quick response and professionalism in both communication and performing the repairs. Thanks to Eydin and the dispatcher who helped me make the appointment (Sorry I forget your name but you are both awesome!)
This is in appreciation of Garrett, who came out this morning on the hottest day of the year.
First of all, I am a big fan of this company. I had mini splits installed last summer and everyone at this company from the sales associate to the techs to the schedulers, is a pleasure to work with.
Most recently, I made my first service call after about ten months with our new units. Nothing was wrong with them, but they were acting like they were being controlled by aliens. I knew it had to have something to do with the integration system - Flair - and I would not be able to navigate this on my own.
By the way, this is during a massive heatwave. Do they make me wait? They do not. I get a service call immediately, orchestrated by the very talented Alex (sorry, I also write theater reviews).
You know how you always have a window? Well Garrett arrived at the beginning of the window. He agreed it was the Flair pucks being naughty, and we both thought it was going to be a simple fix.
Garrett fixed it, and it was complicated, but he never broke a sweat. He didn't indicate frustration, just quietly kept working and answering my questions all the while. People like Garrett is why professionals exist.
He fixed all the issues - meaning, ones I didn't know I had - with the Flair and those silly pucks and gave me a tutorial afterwards and it was like the skies cleared up and I understood the Flair universe.
Another Happy Endless Energy moment. Thanks, Garrett.
Edyin was great! Quick fast service. Our AC at our salon unit broke right before this heat wave. Resined fast with availability next day. Highly recommend .
Eydin is a very professional respectful young man and it was a pleasure working with him he went above and beyond to get the AC working properly before the heat wave thank you so much
