The Ducane 97G2DF110CV20K is a 97% AFUE downflow furnace intended for high‑demand residential heating applications. With heating capacity around 110,000 BTU/hr and support for 5‑ton cooling, it works well in larger homes or installations requiring substantial airflow. Its two‑stage heating system helps maintain more even comfort by adjusting output based on demand, while the ECM blower motor provides stable airflow and quieter operation. The downflow configuration makes it suitable for homes where ductwork is located below the furnace, and the stainless‑steel secondary heat exchanger enhances durability for long‑term performance.
