Recommended Customer Reviews

I've had John and his crew do several jobs for me, and all turned out great. Most notably, AC/DC completed a complete electrical remodel of my boyhood home, built in 1960, in April 2024. They procured the permit, designed the wiring and outlets to conform to current codes, and installed all the new fixtures, which I procured. Everything works great. They've also done some smaller jobs for me, installing new LED light fixtures on my Manteca home.
I highly recommend AC/DC to anyone needing electrical work, large or small!

I highly recommend this company. They are reliable, dependable and deliver on your vision and needs. When you need a great electrical contractor reach out to AC/DC..

John from AC/DC came out to fix my pendant lights. Totally my fault as I was turning them to clean/dust them and one of them got longer about 4 inches. My OCD was in overdrive. Lol. I called them because when I bought my house back in 2016, they installed all my ceiling lights and fans (but not these pendant lights). He was done in 15 minutes. Also had him check and outlet. I'll use them again. Thanks John.

We used AC/DC Electrical and they were amazing. Customer service is the best. We had great communication and set up an appointment. We change a few things in the house and they were very friendly, clean and helpful. Prices were very reasonable . We will definitely use them again. Thanks so much AC /DC

I recently needed some general electrical clean-up in my garage plus an additional outlet. John and his helper not only did the work but made an old garage safe and it looked really good! Their good work was an important part of my house passing inspection and selling in 6 days.

They came out same day and got our electricity up and running without any issues. Thank you for the prompt and safe electrical service. We will definitely call them again.

very poor customer service; I called a week ahead for a service an to have outlets on my kitchen checked. The appointment was made for 9-10am; I came home from work early for this. waited till 11.10 and as nobody had shown up I called ACDC. The lady told me that the technician should have been there and she was going to call him. I told her that I cancel the appointment as nobody notified me in regards of a delay. Very poor customer service; will never use this company.

AC/DC to the rescue! We had an electrical inspection and it didn't pass. The previous electrician didn't install it correctly. Debbie and John at AC/DC are both amazing. They are responsive and were able to fit us in their busy schedule and come out within a few hours. It was a super quick fix, thankfully, and we're ready for re-inspection. We appreciate using a good local business, and getting excellent customer service. Thanks again AC/DC!

We wanted a heated towel rack installed in our small bathroom. We knew it would be somewhat tricky, but John came up with excellent solutions and the work looks great. We would definitely call them for any future electrical work.

Thursday evening I heard a crackling sound come from one of our breakers after turning it on. Immediately turned it off. Next day I immediately started to make calls to find an electrician to see what was going on.
AC/DC was the first place I called and while they said they were booked they listened to my problem and did everything they could to get someone out to us today.
Electrician was in and out within 15 mins
