Upflow Furnace: : Is used to describe furnaces that stand upright and blow air upward. These systems are designed for first floor installation with attic ductwork or basement installation with ductwork positioned below the first floor. Low boy furnace: : Similar to Upflow except the furnace is shorter so it can fit in basement with low ceilings. Down flow furnace: : Furnace goes into the attic and pushes air down through vents. Ductwork may be in a concrete slab floor or a crawl spa...
