If I were you I would learn about the following:
24 volt control wiring
240 volt circuits
convectional heat exchange and the refrigeration system.
Return Air/Supply air/ CFM's and ducting
Because without the basics it will be so foreign you will likely get very discouraged. And the old techs can judge a techs knowledge very quickly and will humiliate you for not knowing anything. I would also examine an air conditioner and how they are laid out and designed.
Thank you, for the advice and the congrats !

So, I guess there is a balance that needs to be attained.
Thank you !

Uh, I hope, I am not that guy !

Ah, the refrigerant cycle ! It took me about 6 weeks of class before that started clicking.

Good advice about the note taking, thanks !
Thanks for the reply !

relays, contacts, safety switches. by mechanical I mean anything that got nothing to do with electricity. based on my experience as long as I know what kind of voltage/current/capacitance/resistance I should get at an electrical device I could do diagnostic on most electrical problems. motor issues will stump me every now and then, but that happened all the time.

oh and 24v will give you a little jolt if you're sweaty. normally it won't.
