Best Custom Control in Chicago IL

Responsive, prompt, knowledgeable expert. Plus competitive price. Stefan was all-around great to work with for our electric garage heater install. Definitely recommend to others.

I have used Penco for years and have always been satisfied with their work. They maintain our generator but we also used them to install smart switches. More recently they installed lights, a new panel and electrical switches to support my small woodworking shop. Everything was completed professionally and they provided me with guidance and consultation every step of the way.

Always great professional service
