I agree with you guys, it probably isn't a real issue but it sure shows poorly. It's looks like an amateur afterthought to me.
It gets better though, how about this one. This is the AC ref line where it exits to the outside of the house. I'm still trying to wrap my head around this.
First photo for reference and the second is a close up. The red and blue tubing that's hanging is just yet to be connected PEX.
