Suspended Ceiling and Duct Conflict

LOL... I can tell you are not an HVAC guy...…....
Ha, I'm only "filter changer" certified for that stuff. No cutting up floor joists for me. And I'm not looking to have the new kitchen island relocated to the basement!!

...anything less and you must install the tile b4 you inatall the cross tees . Takes 3x longer that way but sometimes you have no choise .
Yeah, I did expect to do that from the get go.

Figure out a way to support it from above. If the duct is not supported well...….,
I think I'm good on duct support. It's only a couple feet or so from the furnace and the hangers are close. Going to try a few screws into it.
It really wouldn't have been a that big a problem if they didn't put the intake so close to the output! (where have ya' heard that before) That bent main T is just a couple inches into the intake duct.
The initial picture shows the "end" of the intake on the left. The second picture is the reverse angle.
