    JSA Electrical ROCK!!! Both John and Steve did a great job upgrading our panel from 100v to 200v and adding a EV charging station to our garage. These guys take pride with their work, no shortcuts and cutting corners. They treat our house with respect and concern, like their own. My wife and I are very happy and pleased with the electrical work that was performed to our home. Thank you John and Steve you guys rock!!!

    John was always on time, did a great job removing all of my nob and tube and replacing, in entire house including basement and attic, to make my house safe. Found other newly installed electric that was done incorrectly and fixed it. The job as done right and at a fair price. I would highly recommend him and his company to anyone.

    5.0 Alexandria A. San Gabriel, CA

    John of JSA Electrical Services is a very nice, kind, honest man, as well as an excellent electrician! He installed in-ground landscape lighting in my front and back yards under Japanese maple trees and did other major, significant electrical repairs in my garage and house. I will definitely use his electrical services again and will recommend him very highly to others.

    5.0 Michelle D. Pasadena, CA

    What can you say about the work of an electrician their work is seldom seen but when you need power they are the most important person in your arsenal of home repair. JSA Electrical Services came highly recommend by our ac installation company. We were not disappointed and asked for estimates on other projects. His prices were more than fair and he was able to put in an sub panel that was need to accommodate the new air conditioner. In one day we were able to enjoy our new ac during the hottest day in July.

    5.0 Mark W. Pasadena, CA

    Thank You John. What a nice man you are and you did awesome work for very fair price. I definitely would hire you again and recommend you highly to others. Very hard to find someone in this day and age who embodies the pay it forward sentiment with the skills to match :o)

    5.0 Barney M. San Marino, CA

    John of JSA electrical installed new LED lighting on our front lawn olive trees: in our patio area; and our backyard all of which beats the cost of old flood lights and are much brighter ! He's thorough and very professional taking pride in his work. If something goes wrong at all he is happy to return and solve the problem. He has my recommendation for anyone who needs electrical work done inside or outside their home whether it's a small or a large job!

    5.0 Dermot C. Sierra Madre, CA
