"Joe Electric technicians were on time as scheduled, professional, knowledgeable, courteous, friendly and cleanly. They did the job thoroughly and quickly. After having 2 other contractors flake out on the job at the last minute it was refreshing to have true professionals from Joe Electric come through. I highly recommend them!"

"I had Excellence Electric install a Tesla charger in my garage. The job was difficult and required a replacement upgraded 200 amp circuit breaker with a 60 amp power line pulled through the attic across the house and dropped down into the garage where the Tesla charger port needed to be installed. Raymond at Excellence Electric completed the job on schedule, took care of all of the HOA and city permits, and kept me updated all the way through the process. I can highly recommend Raymond at Excellence Electric with out hesitation for any electrical work needed on your home or office. Kyle Webb Casa Del Sole residence"
