The information age is pretty awesome, we have at our finger tips just about any information you could ever want to know. Maybe too much information though, I mean there are do it yourself hvac videos on youtube. That's a bit of a scary thought to me. I can just see jim bob and cousin cooter after a long afternoon of drinking deciding they need to slam some liquid into their compressor. I'm just a newbie myself as I just started school but seeing some of this youtube stuff brought some questions to mind. I imagine it's pretty hard for the average weekend handyman to get his hands on a tank of refrigerant right? Also anyone ever get any good service calls to homes or office buildings where someone thought they could play service tech only to royally screw things up?
