J T Alder

Mike Valenzuela/Courtesy Electric installed a new electric charger in our garage and we couldn't have been happier with his service. Not only timely in his response to our phone calls, estimate and work the day of, but also courteous, & efficient, including communications with the follow-up City permitting process and inspection. We are very pleased with his work! Highly recommend.

These folks have amazing extended hours. The technician was able to diagnose an issue that stumped 2 others before him. Then he was able to tell PG&E exactly what they needed to bring to fix it-done in an hour!
