The Ducane 97G2DF110CE20K is a high‑efficiency downflow gas furnace designed for residential heating systems that require strong output and compatibility with larger cooling equipment. With a 97% AFUE rating and a 110,000 BTU/hr heating capacity, it is suited for homes that need a substantial and efficient heat source capable of supporting 5‑ton cooling. Its two‑stage heating design helps maintain steadier indoor temperatures by adjusting performance to match demand, while the ECM blower motor provides consistent airflow and quieter operation across a range of conditions. Because it is built for downflow installation, it works well in homes where ductwork is located below the furnace, such as in closets or utility areas. A stainless‑steel secondary heat exchanger contributes to long‑term durability, making the unit a practical choice for homeowners who want reliable, high‑capacity heating in a compact, efficient package
