Map out your duct path to upper floors before you start cutting any holes. Ducts should be able to run between studs in the wall and then turn into a joist bay (the space between two joists). Make sure the studs and bays line up well enough to leave a clear path. Basic Rule No. 5: When you make a turn, use a fitting designed for the purpose. That will keep the air moving efficiently.
