22, 23, and 33 is where the VAV boxes fall. Like I said, I will eat you alive when discussing my line of work. I have installed these many times.

LOL, fine then RV. Ductbenders do duct, plumbers do med gas and airconditioning equipment as is laid out in clear language in the UA constitution. There isn't a word about plumbers or fitters doing any duct work of which VAV boxes are clearly a part and they sure don't do it around here or anywhere else I ever worked. I already proved only journeyman plumbers are allowed to run med gas piping according to Kentucky code. I could care less about anything you have to say further on the matter, I was there and saw it all go down for four decades.
