Looks like the one picture of the second floor vent uploaded having trouble with the attic ones I will keep trying. Notice you can see right up through no filter no nothing.

Without knowing more about the complete geometry of the wiring as is passes through the duct, I cannot say for sure that it is a specific NEC violation, but I sure would say that it is so far from "workmanlike" that no inspector who notices it will pass it.
 
For the life of me I cannot upload these pictures it keeps saying error. Went back took more same thing even took a really short video same thing yet the one of the vent went through. It's not a light issue its plenty bright up there. Any ideas there all on my IPhone 6s right now. You guys really need to see these

This site (forums.mikeholt.com) has limits on the size of attachments that you are allowed to upload. The vent photo probably compressed to a small enough file as a jpeg and the others did not.
You could host the photos on a site like PhotoBucket and the video on YouTube and then just put the links to them into your post.

So far, all of the HVAC contractors who have responded to a post that I made about your case agree that you have every right to be upset. The HVAC person performed sloppy work that ends up making you look bad even though you were not responsible.

I hope he is a stand up guy, and he fixes this at his own cost.

Thx for that it really would not be a big deal for him to move it over cut his own hole same with the grill below. A drywall company is coming in to patch the entire house so he wouldn't even have to worry about it. I was really hoping to find a related article on this. I will figure a way for these pics to be seen. Certainly you can send me your email address and I can send them to who ever wants to see them. Biggest thing that pisses me off is I know they were paid a lot of money for this job shouldn't get hacked. The whole cardboard thing bugs me didn't even attempt to at least caulk in some metal.

OK. The distance traveled through the air handling space is not much longer, if anything, than the spacing between rafters, and technically I guess the wires are now running perpendicular to the air flow rather than parallel to it. So still no single directly citeable Code section, but again, I am sure any inspector who sees it will figure out a way to write it up somehow.
Possibly that his cardboard "walls" are too flammable to be forming a wiring chase. Or possibly cardboard is not an allowed material for that purpose under HVAC codes.

For sure.

Also can't think of any direct NEC violation off hand- maybe something somewhere in 300?? 300.21 or 22??. Do concur about it being failed and inspector finding a way to make it stick.
 
Is the "cardboard" just cardboard scraps or is it actually foil coated product that is intended for use as a duct?

Why does 300.22(B) not apply? There's no exception regarding perpendicular runs.

What is that valve handle for that was under the flooring?

Ugly HVAC work. Where is that grill located from the bottom; hallway, room, ??? Did he have space elsewhere to put it?

No it's in the master bedroom so what happens when that door is closed ? I'm not trying to start trouble but these are nice people and I know this guy got 70K for system in basement and system in attic. Biggest mistake I see besides not enough return is he ran his main supply line down the peak of the attic roof and used flex line in the roof deck channel. Basically squeezed in between the rafters against the roof deck. That plastic stuff might even melt it's so hot right there. Idk minimum he's gotta move that fly by night return it even looks like crap down below hide the wires with a filter next time at least. This is a old but high end home who wants to see that in there master bedroom. Should be returns in each bedroom anyway.

If the "made" duct runs all the way to the outlet or register then yes. If portions of the structure are used as a part of the duct, then 300.22(C) may allow it.

I don't think that 3-1/2" of fir that's attached to the duct work transforms a "Duct Specifically Fabricated for Environmental Air" into "Other Spaces for Environmental Air".

That 3-1/2" of fir was specifically fabricated to be structural support, the HVAC installer happened to use a portion of it as a duct wall.

If they would have used some additional horizontal distance of the joist space as duct we would all probably agree it is "other space for environmental air", but since it is only 3-1/2" inches long some see it as something else, but it isn't. The NM cables are still crossing perpendicular to the air flow just like they would be if the "duct" were horizontal in the joist space, effects of air flowing over the cables is not really any different in either case. Biggest issue with the install is the ugliness of being able to see the cables through the register.
