What is a Heat Exchanger?

Furnace RepairA heat exchanger is a device for transferring heat from one medium to another. It is also one of the most important parts of your furnace. When your furnace burners ignite, the flames are directed into the heat exchanger where the gasses heat up its metal walls. On the inside of the heat exchanger, the gasses (which include carbon monoxide) are then vented out of the furnace. The Furnace fan blows air over the hot heat exchanger and the warm air is distributed through your ductwork.
