"Dan (The Technician) and his Apprentice (Brody) were EXCELLENT) and would give them more than 5 STARS IF POSSIBLE! We have used Dan at Current Electric several times with difficult tasks but he seems to always find a way to get the project done! We had 3 lights installed today, had rewiring so they not exposed and got our projects done that we wanted for 2 years now THANK YOU SO MUCH! I would recommend them to anyone!

"This is the first time I used Mr. Sparky, and they will definitely be my new go to electricians! I love that they are a small locally owned business! I called about a small non-urgent project, and they were able to come the same day, despite being backed up due to many local flooding issues. Kasey was extremely friendly and helpful on the phone and communication was excellent from start to finish. James showed up on time and was very sweet, yet professional, and my cats even loved him :) He was respectful of me and my property, and took care of my issue in no time. The price was very reasonable! I will definitely call them again, and would highly recommend!"

"All of their technicians were very professional and polite and helped me understand what was going on every step of the way, from the initial inspection, diagnosing the issue, deciding on a new furnace, and through the installation process. When the inspection showed that my furnace was no longer working, they even shuffled some appointments around to make sure I had working heat before it started getting too cold outside. Not only did they do a great job installing the new furnace and AC, they went out of their way to clean up the basement and duct work a bit and left things looking even better than when they got there! Mike was my technician for the initial inspection and Austin worked on the Furnace and AC install. There were a couple other techs with them as well who's names I didn't quite catch, but all of them were great!"
