Blocking Furnace Air Return
My wife wants to move a bookcase right over the floor register for our furnace air return. I figure I can build a little stand for it to give air a clear path underneath. So the question is, how tall does this stand need to be so a to have negligible effect on air flow? Since it’s a return rather than a supply, perhaps it doesn’t take much? The footprint of the bookcase is roughly the same dimensions of the floor register.
