Hello from 5,280 Ft. above sea level. About me = I'm a 15 year+ project manager for a commercial GC that decided to switch tracks and take up the HVAC trade. I was referred/hired for/lucked into an apprentice gig on the service side of a pretty stable mechanical company, and at 5 months in it's so far so good. I got my EPA universal right out of the gate, so at this point I'm gathering tools, watching youtube vids, and of course registering on this site. There is some really good reading to be done here. Thanks.
