That's cool! You'll like the HVAC training...I just finished school for HVAC&R about a year ago. I never went into the field, but I'm still doing a lot of related maintenance work. Got my certification to work on all HVAC&R systems, including my MVAC license to work on motor vehicles...now just need to gain some real world experience. If I can find it, I'll send you a program with some HVAC&R training material. It's a real nice tool to help you learn how it all works.
