The blower fans push the air through a ductwork system in your home. This air then moves out through the vents. The furnace will use the same ductwork as the home’s air conditioning system. There is no need for additional ductwork. Natural Gas Furnace Natural gas furnaces use a pilot light to ignite burners in the combustion chamber. The heat from the burners enters a heat exchanger. From this point, the warm air is transferred and heats the ambient air. The blowers push the air throughout the ductwork system. Furnaces that use propane...
