again, I don't do residential for a living.
"usually" the up and down are completely separate.
one return up, one down.
if you can convert it to that way you may consider it. '
its your house and you know the layout.
just keep in mind you want the air to flow BACK to the unit that is running.
I would "hope" the guys that put the system in did it the most efficient way, they usually don't want to waste money running unnecessary duct
