What is a Furnace Blower?
All forced hot air furnaces are equipped with a furnace blower that works to circulate hot air throughout the house. A home heater, or furnace, that uses forced hot air consists of the burner, the plenum, and the furnace blower. In the typical forced hot air system, the burner is fired by oil, natural gas, or wood. Air that is heated by the burner is gathered in the plenum. The hot air is then forced, or blown, from the plenum throughout the house by the furnace blower.
