Can I get a "Hell, Yeah!"? I couldn't agree more, Mike!
When I watch those videos I'm reminded of when I first started out in Commercial HVAC, as I told my fellow Tech School classmates, "If I can't walk inside of it, I don't want to work on it." And thus my first job was working for Mammoth, who made large, custom penthouse systems. Loved those 250 ton and larger units!
