Best Permit Services in Chicago IL

I visited Dunning today who I believe was contracted to replace all unit breaker boxes in my condo several years ago. I first called and spoke with a very pleasant woman who encouraged me to stop by with the faulty breaker needing replacement that was not providing the necessary 120/240 voltages to my electric range. She noted that I should stop by mid afternoon in time to ask the service staff if a replacement was in stock or could be ordered. I did so and was greeted by two knowledgeable service men. They knew immediately what I needed and checked for a replacement in their inventory. I was given a used exact replacement breaker gratis. It resolved my voltage issue with my electric range and so I am once again a happy camper and can cook and bake once again! Thanks Dunning!
