"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."

"After talking to multiple companies, Jay from Mr.Electric showed up. He was very professional and the only one who took the time to plan what I needed. He did a great job installing new outlets and switches for my new kitchen. Ask for Jay!"

"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!"

"Service was excellent. I dealt directly with Joe the President on the specifications. He gave me a number of options at different efficiencies and price points. The work was preformed the 3 first days of Thanksgiving week. All work was performed in a timely and professional manner. The installers took care to highlight the efficiency of the new system and walked me through operation and maintenance. My family is very pleased with the result.

"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."
