"JW. Koehler Electric has always had a welcoming professionalism that makes you sure to call them back for other projects in their area. I used them for our Premier customers and the customers are always happy. They respond quickly and if they can do it they will without charging arm and leg. I would definitely recommend JW Koehler !"

"I needed security cameras installed, and I am so glad I ran across Mitchell through Angi. I can’t say enough good things about this guy. He was on time and communicated well in person and through text. He was fast, effective, efficient, thorough, honest, hardworking, and just an overall decent guy. Once again, my wife and I are so glad that we ran across Mitchell at Freedom Electric and Construction, and we are looking forward to working with him on future projects!"
