HVAC Holliston MA

I hit the Home AC lottery having my new Central AC and AC Split Units installed by Endless Energy! We are so happy with the service we received start to finish with this top Company and we highly recommend them. Beginning with the knowledgeable, helpful and patient sales pro Mike H., the experience of specialists Jeff (Proj. mgr.) and Jeremy/Emmit (Elec.), to the professional, competent and always friendly installation team led by Techs Zach and Paul, we could not be happier with our choice and we love our system! Thanks guys!

A great crew, friendly, explained every step, played with our dog and made sure she didn't get out on her own. I was surprised how many guys showed up over the course of two days for a heat pump installation, but each one introduced themselves and said what their role was. The most impressed I've ever been by any home improvement project crew. Hunter, Joe, Chris...all were superb! Endless Energy are the only people I'd ever call.

Gavin was here to do our mini splits cleaning. He was exceptionally professional, thorough, and careful in his work. We also discussed other home heating issues (e.g boiler maintenance). He was knowledgeable and clear in his explanations. We are confident in his expertise and find him to be genuine and passionate about his work. We can’t recommend Gavin and Endless Energy highly enough since we are very satisfied customers!

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

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.

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!

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.
