All conduit was run beautifully and the all black LG panels look great. All work was done in one day! My sales guy Kevin definitely was knowledgeable about his recommendation and placement. Al in all, this was a really good experience with zero issues at all.

We were told that we did not have any insulation in our home at our energy assessment performed by…read moreBrian. Because of the style of our house, we were also told in no uncertain terms that the insulation would have to be put in from the interior of the home. So we spent weeks preparing by pulling everything off the walls and packing up my husband's small collectibles and moving all of the furniture in every room to the center. And we had to remove the beautiful real wood paneling in our dining room so that they wouldn't drill into it. It's the good stuff, not the cheesy 70s stuff. When the insulation company came, they drilled holes in four different rooms. Every room had insulation. We then had to patch and paint every hole and put everything back where it came from. It was a horrible experience with very little in the way of an apology from the company. When the team came to do the insulation and discovered that it wasn't needed, they asked who had done the evaluation, and when we said Brian, they said that that made sense. Apparently this isn't the first time that something like this has happened to someone. That is shameful! They did nothing to help our energy consumption.

Frank and his team upgraded our fluorescent lighting to LED and the results are amazing! He also…read morehandled some new construction lighting needs we had as well. Not only were Frank and his team very professional, they handled everything from coordinating the electrician to delivery of all materials. They were on time and on budget. Frank explained how we could finance the portion that the rebates wouldn't cover directly through our utility company with NO INTEREST. It was easy to set up and no fuss. Being in the auto collision business, lighting is paramount because we need to be able to see any imperfections in our prep and refinish work, along with color matching. The LED lighting is like having natural sunlight indoors, which in our industry, is gold. I would highly recommend utilizing Frank for any energy efficiency needs your business may have.

What they don't realize is how much focus Uncle Sam is placing on mandated energy efficiency and this is driving huge year-on-year improvements in building-centric systems like lighting, HVAC, refrigeration, window films, insulation, roofing, water systems, building controls, waste management, and more. There are a LOT of tools in the tool belt if you just know how to employ them. I invite you to contact me at fcollins@trustenergy.solutions for a free consultation or to discuss further.

When Chris first came by we kind of brushed him off at first but he followed up in a very professional manner and explained how we could go solar without putting any money down. He gave us the options for both purchasing and leasing the equipment and for our situation we decided to lease. They said customer service is their focus and I can attest. Excellent! They installed our system in one day and took about 5 weeks from initial signing. They said it could take a few months, so i was pretty excited. I'm happy with the process and I look forward my savings. Thanks Chris and Dvinci Team!

Endless Energy installed a Fujitsu heat pump system in my home in October 2022 through the Mass…read moreSave program, and it has never worked properly since day one. From the start, the system constantly shut down and threw error codes. We were actually told by their team that shutting off power to our entire house for 30+ minutes to reset the system was an acceptable solution--something we had to do multiple times per week (and sometimes multiple times per day). That alone should have been a huge red flag. Winters were even worse. We haven't been able to use it at all during the coldest months and were told that just happens in New England winters. We've been forced to rely heavily on expensive oil heat while still paying for this system. They attempted a few fixes over the first couple years, including installing a surge protector, but nothing ever solved the issue. The system continued to fail repeatedly and has now been completely unusable since December 2025. We recently had an independent electrician evaluate it, working directly with Fujitsu, and the system now needs a new compressor and control board. Even more concerning, it appears likely that the root issue may stem from the original installation or wiring--something that was questionable from the start. The installers often seemed inexperienced and had to call others for guidance several times during the install. To make matters worse, Endless Energy now wants to charge us just to come out and diagnose a system they installed that has never worked correctly. They are apparently under new ownership with significant staff turnover, and at this point have been completely unwilling to take responsibility or meaningfully help resolve the situation. After 3+ years of issues, missed work for service calls, ongoing loan payments, and thousands spent on backup heating, I have zero confidence in their ability to fix this. I would strongly caution anyone considering using Endless Energy.

I've never left a negative review before, but I felt this needed to be shared…read more I had a brand-new LG mini split system installed in 2022. Within 8 months, it stopped working properly and was only blowing room-temperature air in both heat and AC. A technician came out, diagnosed it as low refrigerant, and repaired and recharged the system under warranty. Now, just a couple of years later, I'm experiencing the exact same issue again. After testing, they confirmed it's once again low on refrigerant--but this time I was quoted $2,500 for repairs because the 1-year labor warranty has expired. I declined the repair and was told a manager would follow up, but I never received a call. This appears to be an installation issue that was never fully resolved--just temporarily fixed with a recharge the first time. Unfortunately, I had referred Endless Energy to several others after the initial install. Based on this experience, I can no longer recommend them. I would suggest finding a company that stands behind their work and properly resolves issues the first time.

Mark took whatever time was necessary to air seal in our unconditioned attic, install baffles, and also ensure that the insulation which was poorly placed on the surface was cut down properly so it could be in contact with the attic floors. I don't know how much energy savings air sealing will do for me as my newer house was already pretty comfortable before embarking on this project, but I am confident that this project has been completed in the most competent manner possible. I did receive quotes which were a lot less than Mark's, but still chose to hire Mark for the job since he seemed like he was going to take the time to do it correctly. After seeing how big a job it was, I really don't feel confident someone would have been able to do the job right at those lower quotes. The project ended up being about 4.5 days of work where Mark had to crawl through insulation for many hours to get the job done.
