Best Breaker Box in San Francisco CA

Harry and Alex have gone above and beyond with their work. They are great at communicating when and where they will show up, what type of work they have been doing, and what you need to do going forward for maintenance if necessary. When I say they went above and beyond, I mean that my housemate accidentally blew a fuse on New Year's Day, and Harry and Alex were at the house within 15 minutes to identify the issue and fix it, and we haven't had any issues since then. It was incredible. They also handled a potential headache with the permitting office and got everything done quickly and with minimum work on my end. I love their professionalism and will be happy to hire them again.

Sergio & his team do phenomenal work and have been regular electrical contractors for both our HOA and for my extended family. He was able to scope and deliver a very complex EV charger project involving splicing new subpanel for all units in our building and then wiring each parking spot to be EV ready. His team completed all of the work extremely efficiently, pulled permits and coordinated inspections, and delivered the full project on a quick timeline and within budget. He also helped to repair our aging heating elements and wired our new appliance system. I would highly recommend Sergio and his team for any electrician project - they are the best!

I am super happy with Carlos from Guerreros electric. We had another electrician come in and tell us we had to change the wire and replace fuses and outlets and breakers and it would be over 2000 dollars! It didn't seem right so I called to get a second opinion. I spoke with Carlos explained my problem and sent him a couple of photos. He was able to come the next day and do the minor job at it wasfor under 400 dollars! It did not need replacing! And I could not have been happier with the service and promptness!

I called for a quote and got a cold hello with a subsequent complete dismissal of my request for electrical work. Avoid this place!
