I got a question about the phase change topic. In the article it was stated numerouse times that before building your own setup, it would be prudent to get HVAC certified. I have a question about that. Where would one go to get this certification? Are there age restrictions? How much is it? and this may be really dumb, but how is it pronounced?....
(H-V-A-C) or H-vac (as in vacume cleaner)
I have read a couple articles about phase change setups, and all of them say that getting HVAC is a good idea, but no one gives any details about the course/certification itself. I would really apreceate any people that are already HVAC certs to shed some light on this.
Thanks
