Description
The Rheem-Ruud AS-61579-05 is an OEM replacement heat exchanger designed to restore safe, efficient heating performance in compatible Rheem and Ruud furnace systems. As a critical component in the heating cycle, the heat exchanger transfers combustion heat to the circulating air supply while keeping combustion gases completely separated from the conditioned air stream — protecting occupants and maintaining indoor air quality.

Why Replace a Faulty Heat Exchanger?
A cracked or damaged heat exchanger is a serious safety hazard, as it can allow carbon monoxide and other combustion byproducts to enter the living space. Replacing the heat exchanger with a genuine Rheem-Ruud OEM part — like the AS-61579-05 — ensures the furnace operates safely and efficiently, extending equipment life and maintaining manufacturer performance standards.
