"What can you say about the work of an electrician their work is seldom seen but when you need power they are the most important person in your arsenal of home repair. JSA Electrical Services came highly recommend by our ac installation company. We were not disappointed and asked for estimates on other projects. His prices were more than fair and he was able to put in an sub panel that was need to accommodate the new air conditioner. In one day we were able to enjoy our new ac during the hottest day in July."

"Robert did an amazing job installing several 3-way Leviton WiFi smart switches in the stairwell of my home. He was very professional, detail oriented with the install, and did a great job sharing the info with me on how he set things up! The work areas were all cleaned up and he took his time to make sure everything was pristine. I definitely recommend Robert if you’re looking to have any electrical work done. Thank you!"
