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.

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.

NEGATIVE 1,000 STARS…read more I hired HomeWorks Energy for attic insulation through Mass Save. I paid nearly $3,000 out of pocket -- while HomeWorks reportedly billed the state program roughly $16,000 for the same job. Draw your own conclusions about where that gap goes. The crew did not properly seal or protect the area they used to access my attic. While spraying insulation foam, they let a can explode, coating a leather messenger bag that my late father gave me shortly before he passed away. It's now ruined -- foam soaked into the leather and fabric strap, and no amount of cleaning has restored it. On top of that, one of the crew members' behavior raised serious safety concerns. He spent much of the appointment with his face covered, sitting in his running vehicle, and locked in my bathroom. He repeatedly drank Gatorade and had to lean against the truck to steady himself. He then bolted out of the house and ran head-first at full speed toward the HomeWorks truck parked on my street, nearly colliding with it. I'm not sure if he had a hard night out before visiting my home that morning, but he never should have been dispatched to a customer's home in that condition, with my family present. When I raised the damage to my father's bag, HomeWorks' "resolution" was to offer me the value of a refurbished/used bag from an outlet -- not a new one, despite this being a gift I received brand new. I've asked for a full refund of my co-pay, retail replacement value, and a formal apology. I have also repeatedly asked -- by email and by phone, on multiple occasions -- to be connected with the owner or any senior member of management. Every request has been refused. A company that stonewalls customers from reaching anyone above a customer service rep, especially after property damage and a safety incident, is hiding behind its front-line staff rather than taking accountability. If you're considering Mass Save's insulation program, ask specifically NOT to be assigned HomeWorks Energy. Based on my experience, this company should not be a state-approved vendor, and I'd urge Mass Save and the DPU to reconsider this relationship. Save yourself the headache and go elsewhere.

Don't plan on saving ANY money unless you have oil or electric baseboard and you may need a new 200-A electrical panel to accommodate the heat pump load.

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.
