"Roy is really a prof. He installed two overhead fans and a hanging lamp. The fans had a complicated control system but he was able to get them to work flawlessly. Bonus: he is really a nice person and he cleaned up too! I would recommend his work to anyone."

"I asked for a team to install and wire 8 kitchen can lights. Great professional team that came in on time, did a great job protecting the kitchen, finished the job in less than 2 hours, and cleaned up behind themselves entirely. They charged a very reasonable price, and made the whole project as smooth and seamless as possible. Definitely recommend for your project."

"Extremely well. Although the generator was installed some time ago by Doug, a new problem arose with the central air conditioning when the electric power went out and the generator needed to run. Doug spoke with the company servicing the generator and the air conditioning to find a solution and fixed the problem. At my request, he communicated long distance with my son (an engineer), to explain what was happening, as I had little knowledge of the problem and solution. Doug spent considerable time and triple checked that the solution was working before he finished. As always, Doug was extremely caring and efficient."
