Description
The Rheem-Ruud AS-90645-11 is an OEM replacement heat exchanger engineered specifically for Rheem and Ruud heating systems. Designed to restore peak thermal efficiency, this heat exchanger ensures safe and effective transfer of combustion heat to the air supply while maintaining the integrity of the flue gas pathway — keeping harmful combustion byproducts fully separated from conditioned air.
Why Replace Your Heat Exchanger?
A cracked or deteriorated heat exchanger is one of the most serious issues in any forced-air heating system. It can allow carbon monoxide and other combustion gases to enter the living space, posing significant health and safety risks. Replacing a failed heat exchanger with a genuine Rheem-Ruud part restores safe, efficient operation and extends the service life of the furnace.
