"5 stars! Mark Chapman with US Energy Solutions just installed a manual transfer switch box for my portable generator. The work was done professionally, on time, and very reasonably priced. Mark tested the install before he finished and it was perfect the first time. He was knowledgeable and experienced. My next electrical project will start with a call to Mark!"

"Fantastic! We had hired a handyman from SMAP ( send me a pro ) to install a new bathroom door for us and he did such a terrible job that the door would not even close. Hg came out and corrected the situation so we now have a perfectly functioning door. We now know who to recommend , and who not to recommend, when work needs to be done."

"Jay came out looked at the issue and gave me a quote to fix it. He was professional and so was his employee. They came a few days later fixed the issue with precise and increíble workmanship and kept me infomed the entire time. They cleaned up when done and stayed exactly on his original quote. No surprises or tons of extra costs. Very professional and I would absolutely hire him and his crew again. I highly recommend this company to anyone."

"They were quick to reply to my quote request and Blain arrived when they said he would. I noticed my water heater had gone bad around 11:00am and they had the new one installed around 6:00 the same evening. Blain was extremely nice, professional, and respectful and the work seems to be top notch."
