"The process from beginning to end was highly professional, technically very competent and complete, and the installation was impressive (Team of about nine people, all worked efficiently and simultaneously outside and inside my house. The job was done in a little over half a day. Very happy with my decision to hire GAC to spec, supply, and install the system."

"Our existing generator died. James diagnosed the problem and gave us a few options to repair or replace it. We chose to replace it. James handled everything, from getting and installing the new generator to electrical and fuel (propane) connections. We have asked him to schedule us for the annual maintenance on the machine. We are pleased, though we haven't lost power since it was installed, LOL."

"On June 10, I had a company to install security equipment in my home. In doing so, the installer drilled through a wire and I did not have electricity in several outlets due to the damage. Since the company did not have an electrician on staff and was unable to refer me to anyone, I turned to Angie’s List for help in finding someone to correct the problem. I called Hands on Electric on June 11 and spoke to the owner, Kevin Williams. I explained my problem to Mr. Williams and he gave me a window of time in which he would be able to come out. Not only was he able to come out the same day that I called, but Mr. Williams was able to come much earlier than expected. Once he arrived he was able to trouble shoot and diagnose the problem. Mr. Williams was very, very friendly, professional and honest. He was able to answer my husband’s questions and explained what he was doing as he made the repairs. My husband was very happy about that and we were both impressed by the years of experience Mr. Williams had for his age. I have been looking for an electrician for a while now and have decided that I will be using Hands on Electric for all of my future projects. I was very pleased with the work that was done by Mr. Williams and will recommend him to my friends and family when they need of electrical services."
