"I'm very satisfied with his work. I had used him for 16 years and I had him install two different generators. I never had any problems at all and he is very responsive; that is why I have recommended him before."

"VERY pleased! Was able to make an appointment ASAP. On time, courteous, knowledgeable, trustworthy, honest, and very friendly. Bo knows his stuff! How he adroitly repaired my Casablanca ceiling fan switch & tested it in short order was amazing. I'm now having him service my Generac generator on a routine basis. I'd call Bo for anything electrical any time!"

"Very professional, friendly, clean and fast. He even fixed some bad plumbing the original installer had put in, without charging or complaining. Price was what he quoted plus a few hoses and valves that had to be replaced. Would definitely hire again."

"This was the first time I used D-Tech Systems. I needed an electrician to reinstall a chandelier. Daniel Malachowski (with D-Tech Systems) was polite, extremely efficient, very conscientious about keeping the work area clean, and did a professional job in a short timeframe. During that same visit, he was able to resolve a couple of other electrical items and showed me how I could fix a simple item myself. I will use D-Tech Systems in the future and would definitely recommend them and, in particular, Daniel M."
