Hi my name is Anthony, I had homework's energy company come…read moreout to my home in Randolph to insulate my attic the crew that was sent out Gus, Luis, chistrin, Chris. Gus came into my house very respectful very polite and very friendly told me what his crew were going to do in the attic and they did actually what they said there were going to do and in a timely manner two days like Gus said. Chris came by several times to check on the guys to see if they needed anything and also checking with me and at the end of the second day came back to see how the job was done. I was very satisfied with the work the attic looks, amazing job well done. very efficient, testing the house for tightness before and after insulating. I could see the difference before and after it was like closing several windows in the house. my central air system was cooling down the house a lot faster than normal. overall was very satisfied with the work and the quality of work. (Cleaned up like they were never here) Best regards Anthony Would recommend this company Very highly. thank you, for a job well done.

The crew arrived late and began the job. 4 hours go by and the lead guy is talking about it coming back the next day because he had a job in Dover MA that he needed to attend to. I informed him that he needed to come back tomorrow and complete the job. He arrived next day and I watch as him and his partner rush through the job. He leaves holes in walls, my garage is full of insulation materials that he didn't blow in correctly, they failed to address a back wall (I have cameras there) although he tried to lie until I pointed out the cameras. All in all they did a terrible job. 2 days later the pipe that was supposed to be insulated froze and cost me $250 to have it repaired. I called the office and reported what happened and basically got the runaround. Eventually, they sent out a second group who noted several inconsistencies in the job that was supposed to have been completed. At this point, I realized that I no longer wanted them back up my home because if you lied to me the first time you'll lie to me the second and third time. I contacted the office again and I asked them to give me back some of my money so I could hire a company to complete the work that they did not do that is verified by their own second team contractors. We've been playing this game for the past four months. I contacted Adobe the company that hires homework and to date I have not gotten any satisfaction. I read the reviews on homework energy into my surprise or Betty yet to no one's surprise, they are the worst company out there. They do half ass jobs and when you call to complaint they give you the runaround.

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.

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.

He completed the audit and went over all of his findings thoroughly. He explained the improvements our home needed to be more energy efficient as well as programs that we might be eligible for (interest free loans, no cost updates and general tips to improve energy efficiency.) The next step was to get our attic more insulation and our bathroom exhaust. Younes and Hector arrived at our home as scheduled for the improvements (again ETA was communicated and they were precisely on time.) They were professional and respectful; Younes and Hector communicated every step they were doing while making sure that they kept their work station clean (they left without leaving a trace.

ZERO stars for Homeworks. If this was a publicly-traded company, I would short the stock…read more My Homeworks saga has been going on for more than a year. They were hired to upgrade an electrical panel and install and heat pump hot water heater. From the beginning, there were some red flags. The wrong team (insulation) showed up for an energy audit for HVAC services. I was sent a quote intended for another customer - and it took over a week of back-and-forth with three people to get the right quote. Still, I signed up because I've had some sub-optimal experiences with small contractors, and the larger Homeworks organization appealed to me. I was also buying the convenience of one-stop shopping for MassSave and Heat Loan processing. Big mistake. One year update: 1) Heat pump hot water heater does not work. 2) I have been bounced-around to numerous people. In total, at least 20 people have been involved in the installation of the hot water heater. 3) I ended up directly managing the subs on the project (plumbing and electrical). This was done out of necessity, not preference. 4) A final electrical inspection was done, and then re-scheduled twice because the electrician didn't have a process for accurately recording project inspection status. 5) I am convinced that decarbonization/electrification efforts in progressive states like Massachusetts will fail if my experience is at all indicative of what it's like trying to replace gas-fired equipment. I should note that the quality of the work performed, once it was performed, was quite good. The issues with Homeworks are less about the work done in the home and more about the people working in the office. This company is in desperate need of restructuring, overhead reduction, and a stronger focus on operations. It would be a good business school case study. If you can find good contractors, I recommend hiring direct and navigating rebates and Heat Loan financing on your own. Avoid the Homeworks morass if you can!
