Single & Variable High Efficiency Furnace | S9X1 | S9X2

S9X1 and S9X2 are high-efficiency gas furnaces built for reliable, quiet comfort all winter long. Both models deliver up to 96% AFUE efficiency and feature a high-efficiency constant torque ECM blower motor — a major step up from standard PSC motors in energy savings and quiet operation. The S9X1 is a single-stage option ideal for homeowners who want 96% efficiency and ECM airflow without paying for two-stage technology, while the S9X2 adds a dual-stage burner for improved temperature consistency and efficiency during milder weather. Both are ENERGY STAR certified and built with American Standard's legendary reliability.
