What is the purpose of a blower in a gas furnace?

The purpose of a blower in a gas furnace is to circulate heated air throughout the space. The blower is a critical component of the furnace's heating system, as it draws the air from the home, passes it over the heat exchanger where it is heated, and then pushes the warm air back into the living areas. This process ensures that the heat generated by the furnace is effectively distributed throughout the entire space, providing comfort and maintaining the desired temperature.

By circulating air, the blower also helps to maintain consistent heating, preventing cold spots and allowing for a more efficient system. It supports the overall operation of the furnace by ensuring that warm air reaches all rooms, enhancing the heating system's effectiveness.
