"There was no electricity in one of our rooms. They found it was the sending unit in the ceiling fan not sending a message to the switch. 15 minutes later, remote reprogrammed. Mike wrote down the instructions if this should happen again. Great guys"

"Perfect and smooth journey, Jorge came pre instillation to check the electrical panel and where the the charger was going to be installed and after the review he text me the cost of parts and installation, after I received the charger he came on time and the job was completed. I was updated by text messages throughout the process. In the future if I need any electrical work I definitely use JK Flores Enterprise."

"Wilson Electric was great to work with, they promptly responded for my request for a quote and provided me an estimated price for the job as described. The day they arrived to do the work, they finished in about 2 hours and made sure we were happy with the job. I would use them again in the future."

"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"
