Certified called Monday morning to respond to my online weekend request. Gary spent 15 minutes with me on a busy Monday to explain the likely cause of my most pressing issue (GFI tripped on socket near breaker box) and possibilities for my other less pressing issues. First class response and attitude puts them top of the list for future service! Socket in garage lost power, but no breakers tripped at panel. Other miscellaneous projects pending.Gar
