Recommended Customer Reviews

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

John and Debbie are the best
Awesome service
John is very knowledgeable, quick and efficient service
We have used them twice now and I would definitely use them again!!!

ACDC is awesome. John knows exactly what he's doing - 30 years in the biz! And Dianne in the office is great! She knows how the system works. I've enjoyed working with these two immensely!

I've used AC DC in the past. This time, I needed to bring the electrical for my older rental property up to code. John, in my opinion, is probably the best electrician in Tracy. I've had other electricians look at that home in the past, only to shy away from the difficult stuff. John (along with his great associate, Cynthia) tackled all of my problems, and actually solved them and explained to me exactly what was wrong in every instance.
Issues were identified, brought to my attention, and corrected. If you're looking for cheap labor, this is not for you. If you want the job done right, use AC DC. It's a great experience when you know that your electrical is safe.

Excellent communication, speedy response, straightforward pricing, fast service, very pleasant to deal with. Job done perfectly, will definitely hire John for more projects in the future. A+

We've used John and AC DC on our rental properties here in Tracy and have been very happy with their work. Debbie in their office is fast and courteous about responding to calls and scheduling and their pricing has always been fair and reasonable.

The light switches on the house bathrooms were having issues, and AC-DC Electric was able to fit me into their schedule for same-day service. I am pleased with the work, the time it took, the cost, and the professional attitude of all involved.
