    Unprofessional, pressure-sale tactic, model calculations not up to date, price inflated.

    Due to the field of work I do, I am a perfectionist for detailed work from those that I hire. The…read moreguys from Energy Monster did a fabulous job on my 4kw LG system. Installers were Tim & Lyle. 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.

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.

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.

Garret, Gavin, Keith, and Rich handled the installation and did an exceptional job. They were professional, knowledgeable, and took the time to walk me through everything--from how the system works to setting up the thermostat and even how to replace the filter. Their workmanship and communication were top-notch. I also want to recognize Nick and the team working behind the scenes. Nick has helped us through our no-heat situation,put together our proposal quickly, and arranged a weekend installation to make sure we weren't left without heat. His coordination and responsiveness really stood out. Every part of this experience was handled with care and professionalism. I would recommend Endless Energy to anyone without hesitation. Todd R

    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.

    GO ELSEWHERE! Simply put you will get the B Team (at best) and all the forms of sloppiness that…read moregoes with it. Some here have gone into detail as to how you can screw up a basic insulation job, so I won't repeat it. The number of screw ups and amateur work quality was more than I've ever seen in 30 years of home ownership and contractors work. The highlight: they core drilled through structural 2x4s inside the wall, under window framing. Who the F does that?! Everything from communications, to quality of work, to damages, to explanations, to billing / paperwork, slop/mess/clean up, it goes on. Ghosting communications to the office and field lead. Yes, they came back to fill in the various areas where they put NO insulation at all in several wall cavities...but, really, how do you just miss that unless you've been on the job for about a week. The only reason I got them to do that was I got a temperature gun that showed several places where it was a cold wall... They came with a IR image gun and verified various empty areas. What kind of training and qualification do they go through? and oh yea, one of the crew wanted to sit in my hallway for long periods of time, because his feet were very cold and he had nothing to do. When he was 'working' he was on his phone talking and texting non stop. I am not making this up. On each of two crews, there was one person of the three that was competent and able to communicate reasonably well, and two who were not. They meant well, but just not up to the task. Find a real insulation company with a real crew of adults.

    Such a terrible set of experiences with HWE. I went through MassSave to get their services:…read moreinsulation and other heat-saving measures, including door jambs, blow-in insulation, and expanding foam in foundational joists. In total they required THREE separate trips, which I'll expand on: 1) Initial visit -- 2‑br, 1‑bath job. I was onsite for the first half of the full day's work, and they were great in the kitchen and living room: they put up plastic sheeting and handled dust/debris carefully. I left them to finish, assuming all was fine. Unfortunately, both bedrooms and the garage were NOT plastic-wrapped as they had been where I was present; they were an absolute mess when I returned (see images). I had moved everything to the center of each room to make it easier to cordon off, but everything -- most frustratingly my bedding -- was covered with dust, drywall particles, and insulation. I don't understand why the don't use a shop-vac while drilling to cut back on the mess. I would have assumed HEPA everything but instead it's just drill and blow insulation. Additionally they used the green-lid 24-hour joint compound on the drilled holes; that compound would be fine alone, but they applied two coats only a few hours apart, which creates too much moisture and causes cracking, something anyone who has used joint compound before would know. That requires much more post-processing sanding and reapplication to get a smooth wall (also shown in another image). Also, many of their styrofoam 3″ inserts used to plug holes protruded well beyond flush with the wall and required complete removal and reapplication. If the inserts were close to flush, a few coats of joint compound would have fixed the elevation, but these protrusions were extensive and made repairs take about three times longer than necessary. I spent many weekday evenings and weekends cleaning and repairing and to this day find pockets of my quarters in a layer of drywall & insulation. -Adobe Energy, an independent verification company, came onsite about two months later. The rep was great, found several cold spots in the walls (well documented), and advised another visit to remediate them, plus noted poor door-jamb installation and a missed foundational joist insulation spot. 2) Scheduling was reasonably responsive. The second HWE crew remediated some of the shoddy work from the first trip (door jambs and joist foam patches). For some reason they didn't fully reference the Adobe Energy photos and drilled many more holes in the patched walls than were necessary. They attempted to use their blow-in insulation machine but said it was non-functional and that they would need to return a THIRD time. I was understandably upset but I tried not to take it out on the reps. They promised an escalated call from a manager that day to reschedule; I did not receive it. I waited until mid-afternoon the next day, then called. The scheduler was empathetic; she initially said the next available slot was three weeks out, which I told her was unacceptable given the circumstances and state of holes in my wall. She said she'd follow up after working on scheduling and, after about an hour, called back to say she could send reps the next day. 3) The third visit finished the blow-in insulation and patchwork. Unfortunately they were NOT given the pictures from Adobe's assessment, I made it clear we wouldn't progress until we could reference the pictures. The rep made some emails/calls and got the pictures, we reviewed and executed. I lost another weekend to joint compound, sanding, priming, and painting. HomeWorks Energy demonstrated widespread incompetence: broken equipment, poor onsite training, and low-quality materials (they even had a duct‑taped blade they were using - see image). Whatever they're billing MassSave clearly isn't going back into operations or equipment. I lost multiple weekends cleaning up their mess, and it's a shame to see a good MA program affected like this. I would warn people to stay away from HomeWorks Energy at all costs and look to other contractors.
