The S8X2 furnace offers two stages of heat for comfort in cold weather, while maintaining the DNA that American Standard is known for: quality and reliability. The S8X2 is rated at 80% gas efficiency (AFUE), providing energy savings and a consistent flow of warm, comfortable air in both winter AND summer.

Two-stage furnaces can achieve more consistent temperatures throughout the home compared to a single-stage furnace.
