Amana-Goodman 2821300S Primary Heat Exchanger

The Amana-Goodman 2821300S Primary Heat Exchanger is an essential component of any gas furnace or heating system. This is a metal chamber that transfers heat from the burner's hot combustion gasses to the circulating cooler air in your house. In order to effectively warm the air, the heat exchanger's fins or tubes increase the surface area contact between the hot gasses and the cooler air. Your ducting then distributes this heated air to maintain a comfortable living area. For a furnace to operate safely and effectively, the primary heat exchanger must be replaced if it is cracked or broken. Defective heat exchangers can cause harmful carbon monoxide leaks as well as poor heating efficiency.
