The Ducane 97G2DF090CV20K is a high‑efficiency 97% AFUE downflow furnace built for homes that need stronger heating performance and compatibility with 5‑ton cooling systems. With heating output in the 90,000 BTU/hr class, it is suited for larger residential spaces or installations requiring higher airflow. Its two‑stage heating design helps reduce temperature swings, and the ECM blower supports smoother, quieter airflow across different operating conditions. The downflow layout allows the furnace to be installed above the duct system, making it appropriate for closets, utility rooms, or other spaces where downward airflow is required. A stainless‑steel secondary heat exchanger contributes to long‑term reliability.
