Upflow vs. Downflow and Horizontal Flow Furnaces
Airflow configuration — upflow, downflow, and horizontal flow — is just one factor you might need to consider. Upflow furnaces are great for homes with the furnace installed in the basement, while downflow furnaces work well when the furnace is in an attic. Horizontal-flow furnaces are ideal for homes with limited space.
