I was a painfully picky installer because I knew that something looking off leads a homeowner to look for more.
My guess on the duct is that he didn't want to end up going below the metal pipe because that would put the vent pipe below the main trunk and that would mess things up for framing a bulkhead and boxing the duct in for a drop ceiling.

Thanks guys, great info. In regards to the AC lines my concern is the butchering of the wooden framework that was completely unnecessary but I would have preferred he run it that high so I wouldn't have to box the line in to drywall the ceiling. Again it just looks amateurish and hack to me.
It does sound like I might be overthinking it though which is why I'm bouncing it off you guys. Sincerely, thank you all.
