"Dave, was professional and reliable. He did the job very well and returned when we had questions and resolved them. We upgraded our service from 100 to 200 amp electrical service. We also installed a charging port for our new electric car. We are very satisfied with the new service and charge station. I would highly recommend him to others."

"I called them for a basic service the day after Snomagedon2015 fully expecting not to get anyone out for at least a few days. Someone was at my door within 3hrs! Answers all my silly questions, provided helpful information and advice and cleaned up when he was done. Will definitely be calling them back for future service and installation when the time comes!"
