This week we’re going to discuss the differences between the function and characteristics of Downflow vs. Upflow Furnaces and how to tell which system you have.

An Upflow furnace takes in returned air from the house through the bottom of the furnace while heating the air and sending it into the ductwork feeding the warmer air to the interior rooms.  As you might expect Downflow furnaces operate in the opposite way that Upflow furnaces do by taking the air from the top of the unit and sending the heated air out the bottom of the furnace into the ductwork.

Generally, an upflow furnace must be installed in a basement on the second level of a larger home so the heat can rise most efficiently through the system. A downflow furnace is best installed in the mechanical closet with the ductwork in the crawlspace. By paying attention to the locations of the registers and locating the ductwork in your home you can identify the configuration of your furnace.

Incorrect design or placement of either of these furnaces can result in taxing the equipment, causing excessive amp draw or power usage. This will inevitably increase your utility bill and reduce the efficiency of any system regardless of the brand or cost of the equipment.
