The Ducane 97G2UH090CV12K is a high‑efficiency 97% AFUE furnace designed for upflow or horizontal installations in homes that require 90,000 BTU/hr heating capacity paired with 3‑ton cooling. Its two‑stage heating operation helps maintain more even indoor temperatures, while the variable‑speed ECM blower supports quieter performance and improved airflow control. The furnace’s 21‑inch cabinet width allows it to integrate with a range of residential duct systems, and its stainless‑steel secondary heat exchanger contributes to long‑term durability. This model is well‑suited for homeowners needing a balance of strong heating output and efficient operation in a flexible installation layout.
