"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."

"My house project was a trouble shooting on many outlets and lights that were not working, upgrading the electrical panel, rewiring and replacing ceiling fans, installing lights in new patio. At my business (Auto dealership). Replacing old lights, upgrading electrical panel, adding new light fixtures in lot, troubleshooting and repairing some faulty outlets and switches at the office. Francis does a very accurate and precise quality work. He keeps the jobsite clean that barely anybody notices he is working or repairing and installing fixtures. Needless to say he has a great personality toward his clients."

"Mr. Johnson and his crew have performed a fewjobs from lighting installations, to doorbell repair, to rewiring. Every job has been done well and at a reasonable price. The workers were respectful and very helpful at explaining the work they did before they left. What really set this outfit apart is Mr. Johnson himself. He always returns calls, his crews show up on time and perform the work expediently. On top of this, when I have had questions about other electrical concerns, Mr. Johnson takes time to have a phone call to consult on the issue. Mr. Johnson and his company are of high integrity and I would highly recommend them for any residential electric work."

"I recently had Narek install a Tesla wall connector in my garage in Los Angeles, and I could 't be happier with the service I received. Narek was not only professional and knowledgeable, but he also got the permit required for the installation very quickly. He arrived on time and took the time to explain the installation process and answer any questions I had. The installation itself was done quickly and efficiently, and Narek made sure to clean up after himself once the job was complete. He also took the time to show me how to use the wall connector and ensure that it was working properly before he left. Overall, I would highly recommend Narek to anyone looking to install a Tesla wall connector. His professionalism, attention to detail, and expertise made the process easy and stress-free, and I am thrilled to now have a reliable and efficient way to charge my electric vehicle at home."
