Craig has been a keystone in my learning of the HVAC field. I went from being an installer of seven years not knowing how anything worked, to being able to fully diagnose some of the more complicated issues without any assistance from more experienced technicians.

Thanks for putting this out Craig. It is rare to find a true craftsman in the trades. Most people are just content to make it work but to truly understand how it operates and runs at optimal performance is the right way to be.
