Keep your take offs 2' or so from any change in direction or reducer.

If your trying to keep thew house smoke free. then get a PTAC, or some other source of heating and cooling for that addition.

If you use a duct from the main unit. then it will also cause air from the addition to be forced back into the home. And you won't have a smoke free home anymore.
