Kevin Pitts

I haven't had the service yet, however we had Gavin Periera come by to estimate and it was far and away more professional and knowledgeable than three of their competitors that tried to estimate without the correct supplies.

Ava Wood

I had a delightful experience with this company.They have amazing self booking service. They are also very easy to work with and very responsive and respectful.

Lauren Martin

Our water heater was leaking and with no knowledge about HVAC, I called Endless energy to come out and take a look. I thought for sure I would have to wait a day or two and just do water clean up every so often. Endless Energy responded immediately and sent out a technician within a few hours. Don came out and I couldn’t help but stand in the basement like one of those customers watching while he worked. He was extremely kind and patient as he answered all of my questions and concerns. He was very knowledgeable with years of experience and explained every step he was doing along with certain things I should keep an eye on with our system! I would recommend Endless Energy especially those that walk into their basement and see water leaking and have absolutely no clue what they’re looking at! They will walk and talk you through every step and leave you feeling comfortable and assured of the job they did. And as I did, you will feel more knowledgeable about your system!

They did an amazing job installing our water heater.We got to meet this very polite man name Don. He worked great around our schedule.

March 2025:
I had Gavin and Adán diagnose a bad fan in one of my LG floor units. They also installed surge protection in my two outdoor units. There were very professional and friendly. Thanks!

December 2022:
We had two air source heat pumps installed by Endless Energy. The two installers, Matt and Zack were very professional, proficient, and had great attitudes. They made the installation process worry free.

Victoria Nadel

A friend referred me to Endless Energy. I met with Tina who was knowledgeable, helpful, and very kind. The team to install my mini-split, Hunter and Paul, came in what was expected to be a snowstorm but turned out to be some snow and really unpleasant cold weather. They were terrific! They were very efficient, careful, and thorough. The unit was installed, looks good, and works great! I would highly recommend this firm and, especially, the people mentioned here.

Anne Lutz

Garrett was very professional as he introduced himself and described what he would be doing during the repair of our unit. He acknowledged that the replacement part is under warranty and that we would only be charged for the labor for the repair. he explained clearly that the indoor units would benefit from professional cleaning and took photographs to show us the buildup of soiling inside the unit. When I agreed for an endless energy service person to come back to complete the cleaning of these units, he explained that endless energy would be contacting me to schedule this service in the near future. Overall was extremely satisfied with the service that Garrett provided for us today.

Valerie Taylor

We had Endless Energy install heat pumps and mini splits in our home. The staff was knowledgeable regarding the functionality of the system and and helped us with our financing options. The installation was professional and everything was spotless after the installation was completed.
I have suggested Endless Energy to my friends and family as I am confident they are a quality company.

Team West

When my last HVAC tech didn't take my calls for an Xmas eve emergency and another said I needed to be an established client for an "after hours" call, Endless so very graciously took on the job and I mean really took it on, like a quest until it was completed! The tech went above and beyond providing information about my home - what was happening, why and what to expect...and did so with compassion for the stress it caused, which I experienced also from the dispatcher. I am glad to now be an Endless Energy client.

Kimberely Altomere

Hunter and Chris worked ahead of schedule and made certain I had all the information that I needed to feel confident with my new system.
