"I needed someone fairly quick with a faulty outlet. I was contacted within an hour of reaching out to Current Electric. We discussed the problem and was able to set up the service quickly. They were there at the exact time that was agreed upon. The problem was fixed and area was cleaned and all appliances were plugged in. Thank you for the awesome service!"

"Jim is local. It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job. He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer, Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.
