The Ducane 97G2UH070BV12K is a 97% AFUE upflow/horizontal furnace built for homes requiring moderate heating capacity and compatibility with 3‑ton cooling systems. With an input range up to 70,000 BTU/hr, it provides reliable performance for mid‑sized residential spaces. Its two‑stage gas valve and variable‑speed ECM blower help deliver smoother temperature control and quieter airflow, making it suitable for installations where comfort consistency is important. The furnace’s compact 17.5‑inch width and horizontal/upflow flexibility allow it to fit into tight mechanical rooms or attic spaces, and its stainless‑steel secondary heat exchanger supports long‑term reliability.
