[Stephan & Christina]

Can you explain the split system? We'll want / need to keep most of the house, except the attic, at the same temperature, so I'm not sure if we'll gain an advantage there.

If there's a way that I can run a duct up to the attic, I can snake it around the edge, where the roof line and floor meet, and drop down some vents into each 2nd floor room. We'll be putting 2 - 3 foot mini-walls around the attic, so the ducts won't be visible. The tricky part will be to bring the main duct up there without it being too much of an eyesore.

I guess I just needed to write it out to get ideas of what can work.
