York S1-373-27868-405 Indoor Coil

The York S1-373-27868-405 Indoor Coil is a high-performance replacement evaporator coil engineered for precise fitment in 17-inch wide residential furnace and air handler cabinets. Designed with a 16-inch height, this A-Flex indoor coil features 3R circuiting and high-grade tin-coated copper tubing, providing superior resistance against formicary corrosion—a common failure point in standard copper coils. This technical enhancement, known as Tin Coat protection, ensures long-term heat transfer efficiency while maintaining the integrity of the R-410A refrigerant circuit in demanding environments.

For contractors performing HVAC system repairs, the S1-373-27868-405 offers a drop-in solution that optimizes thermal conductivity and airflow. Its compact 17W x 16H footprint is ideal for tight plenum spaces, ensuring consistent moisture removal and cooling capacity. Utilizing argon-welded seams and a robust two-piece copper drain tube, this York HVAC part is built to handle the cycling pressures of modern high-efficiency split systems without the premature leaking associated with unprotected alloys.

• Advanced Corrosion Resistance: The specialized tin-coated finish prevents pinhole leaks caused by household volatile organic compounds (VOCs).
• Precision Fitment: Standardized 17W x 16H dimensions facilitate rapid installation in matching York, Luxaire, and Coleman equipment.
• Optimized Heat Exchange: Tin-plated copper construction maintains high thermal performance for maximum SEER ratings.
• Enhanced Durability: Features argon-welded seams and Powerflex technology for reliable service in gas or electric furnace applications.

• Is this coil compatible with both AC and heat pump systems? Yes, this indoor coil is designed to work with both central air conditioning and heat pump configurations using R-410A refrigerant.
• Why choose a tin-coated coil over standard aluminum or copper? The tin coat adds a protective barrier that specifically targets formicary corrosion, which is the leading cause of premature failure in indoor evaporator units.
• Does this include the drain pan? This model is the A-Flex coil assembly; always verify if your specific installation requires an additional plastic or metal drain pan depending on the furnace orientation.
