"David has done several jobs for us and we have been really happy with his work and would recommend him. He did all the electrical work on a new garage we built, this was a big job. He pulled the permits, ran a new line, installed a new panel, installed lighting and switches. He also completed the wiring and lighting for a remodel we did. Would hire him again, he’s nice guy and does good work."

"It would be very difficult, if not impossible to find another company that has the commitment to excellence that M&M Electric has. I had them put in new central heating and air in my house and was surprised at how quickly they installed everything while still maintaining a high quality standard and while paying attention to every detail. Very impressive considering what they charged for the install was way less than what I was expecting to pay. I will definitely keep their number handy for any other jobs that pop up."
