I would have to disagree.
The dispersion of the supply will be severly disrupted by having the return in close proximity. You'll end up sucking supply air into the return before it has a chance to effectively disperse and reducing the heat performance.
It's not based on tradition but rather dynamics of air flow.

I have to agree with Canuck, you never put a supply and a return on the same wall.
My two cents:)

I would also further the comment that the under window heat/ac units commonly found at hotels that rdsigns refers to, draw the return air from the bottom while spewing the supply air out the top, creating a circular airflow. AT least the unit's that I've seen do.

I'd have to agree with A.Spruce also :)

Yep --- I spend enough time in hotels and those A/C / heaters are crappy for air flow.

Quote from Rdesigns

Remember that the supplies drive the system; their velocity throws air out in a pattern that is determined by the configuration of the register, and the function of the return is actually nothing more than pressure relief of total volume of air that the supply builds up.

HUH??

In order to properly heat a room you have to get the cold air out, otherwise your just dumping warm air on cold and not getting the proper heating your looking for.
The same goes for dumping cold air on warm with A/C, you have to get the warm air out, only other difference is you have dehumidification as the warm air is pulled back. The pressure relief is definitely a factor but not the "nothing more than" that you talk of by a long shot.

Re: Relocating forced air ducts

Why not locate your furnace in the attic, that would solve all your problems. There would be no carrying stick to get in the way and you could put your supplies towards the outside wall and your returns towards the inside wall.

If that's not an option then they do run ductwork on outside walls, but it is always insulated. It's not the best way but it is done quite often, unless you have closets you can use. Good Luck!!! :)

Oh Yeah, seal your ductwork also, LOL :D:)
