Put a new furnace in my garage. It is a upflow Lennox model. I was wondering if it is worth the effort to run ducting from the plenum down to the floor and then coming out at a 90 angle or just run a couple elbows out the top. It would be nice to have heat at floor level but not sure if it would just rise so fast it wouldnt do much good.
