Could not have been better! The main panel blew up on a SUNDAY morning and the frantic search for tech began. Shawn Perovic and the people at Mister Sparky quickly responded. By the end of the day, Shawn had the old panel removed and a new one installed.and running. Who could ask for more? He even upgraded a 50 amp panel to a 200 amp panel. The thing that sold me was that he had all the replacement items already on his truck and was set to go as soon as he arrived.
