Leisanne Doo

James and installation team were knowledgeable, skilled, and courteous. Excellent experience using Endless Energy for heat pump estimate and istallation.

Wes Merrill

My wife and I decided to replace our failing natural gas furnace and central air conditioner with a new furnace and whole house heat pump. Mike and his team from Endless Energy did the complete installation for us. As the project moved along Mike was easy to work with and kept us updated and answered all of our questions. They took care of everything we requested and Mike even went out of his way to modify our attached whole house humidifier, which was not working, so that it will now work correctly.
After completion the team verified that everything was working perfectly and explained how the heat pump and furnace operated and how to control everything using the smart thermostats.
We are very pleased with our new heat pump and furnace.

Endless Energy (EE) installed my full home heat pump and mini split system several years ago. From the sales through the installation, the entire team was fantastic.

Over the years, they've continued to maintain, assist with preventative maintenance (PM) and even addressed some concerns as they have arisen.

Recently, I was experiencing an annoying noise coming from one of my mini splits. I submitted an online service request and they called back the next morning. One of their service technicians, Don Davis, arrived at my home to address my concerns. He's been to my home before for PM and is great. Extremely knowledgeable of my system, professional and just a great guy. He was able to address one of the "noises" but needed a part to resolve the full issue.

EE and Sean Connolly were great about taking care of my concerns and all is well again. These systems are pretty complex, and Endless Energy really does a great job from top to bottom with delivering on their products and services.

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.

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!

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.

Professional HVAC Replacement?

No matter how happy you are with your heating and cooling, your devices have an average lifespan of about 10-15 years. That’s because there’s rapid improvement in the field of HVAC, so newer models are far more energy efficient than older ones. Plus, older systems become less reliable and efficient over time. Let us know if you’re ready to update and upgrade your comfort with a new heating or cooling system! We carry a great selection of quality HVAC systems for any budget and any home. Whether you need a new furnace or heat pump we have you covered!

Don’t Neglect Your Annual Tune-Up

We recommend that all of our customers book an annual tune-up service. Although this appointment doesn’t take long, it can net you some major savings throughout the year. First of all, as your technician cleans and lubricates all relevant parts, they ensure that your system will be operating at maximum efficiency all year.

On top of that, our talented technician will inspect your HVAC equipment and let you know if you need to get any repair work done — which of course means that you’ll be unlikely to encounter any problems with your HVAC system.
