"Highly Recommended! We have hired Zero Electric to do several jobs at our apartment complex including installing a generator, EV chargers, new panel, and even installing recessed lighting in the units. They handled all aspects of the projects and had top notch communication throughout. The team has always been quick and professional. We will continue using Zero Electric for our electrical needs."

"They were prompt and reasonable. They were able to re-wire our kitchen and pull extra electric from the electric main. They also cleaned up the electrical panel and replace bad breakers The only issue we had is that some of the outlets were not level and the right depth for the 1/2" drywall that was going to be installed."

"Ricardo is the best electrician I?ve ever hired. Was very professional and friendly to talk to. Honest pricing for a meter panel upgrade. Did what he said he was going to. Also checked out some lighting fixtures I wanted to get installed in my home as I?ve had several quotes and they were just outrageously priced but he gave me the best price out of 6 electricians! Will definitely hire Rick for all my future electrical needs!!"

"They are knowledgeable and installed the car charging station in my garage. I had compared with other companies who seemed to be cutting corners, and I felt McKee was doing things the right way so I chose them. His communication was good, he was on time, and followed through on what he said he would do. Good, clean, and professional. I intend to have him back out for my next electrical project."
