What is a Furnace Fan?
A furnace fan is the main component of a furnace system that forces air into an area of a home where heated air is needed. Most central heating systems in existence today are forced air systems and therefore require air to be moved in some way. A furnace fan, also known as a furnace blower, is one of the easiest ways to accomplish this. In a heating system, after the air is heated, it must have a way of getting to other areas of a building. The heated air travels through the duct system to those other areas. However, without a catalyst, the air would lose much of its heat by the time it arrived at its intended destination. A furnace fan moves the air much more quickly than it would move on its own.
