Best Load Bank Testing in Denver CO

I stopped by to ask a quick question about a residential wiring issue that I had, i’d taken multiple pictures and was well prepared for any answer. Unfortunately a sign on the door says visitors by appointment only, I called and spoke to “Larry” , He didn’t seem interested in even coming out from behind a desk to talk to me, or even look at the pictures, I get that it wouldn’t have netted him any income, but in the interest of good PR probably should’ve made the effort. Based On this experience I will not be contacting them for any of my residential electrical needs which from what it looks like would be possibly rewiring my home
