These terms refer to the direction the air flows as it is taken in and heated by the furnace. So in an upflow furnace, the cool air is taken in at the bottom, warmed, and then expelled at the top. A downflow furnace, on the other hand, takes in cool air at the top and expels heated air at the bottom.
How does downflow furnace work?
A downflow furnace takes in cold air at the top of the unit and expels air at the bottom. By doing this, the downflow furnace directs heat downwards towards the area that requires it. Heat naturally rises, so the downflow furnace must constantly fight against the natural tendency of the air it’s circulating.
