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.
