York S1-373-27868-402 Indoor Coil

The York S1-373-27868-402 Indoor Coil is a professional-grade evaporator coil engineered for high-efficiency heat transfer in residential and light commercial forced-air systems. This unit serves as the direct replacement for York 373-18108-001, ensuring a precise fit within existing air handlers or furnace plenums. Constructed with corrosion-resistant materials and featuring a tin-coated finish on select surfaces, this A-Flex coil is designed to mitigate formicary corrosion and maintain structural integrity under high-pressure refrigerant cycles. The integrated drain pan is molded from high-heat resistant polymer to prevent sag and ensure positive condensate drainage, reducing the risk of microbial growth and water bypass in the ductwork. Technical specifications indicate compatibility with York indoor coil configurations requiring a 17.5-inch cabinet width, providing reliable latent and sensible heat removal. Using this OEM York replacement part preserves factory performance standards and ensures HVAC system compatibility with the original equipment design.

• Direct OEM Fit: Drop-in replacement for part 373-18108-001, eliminating the need for extensive field modifications to the refrigerant lines or cabinet.
• Enhanced Durability: Features specialized tin-coated copper tubing or aluminum fin stock to protect against environmental degradation and leaks.
• Integrated Condensate Management: Includes a high-temperature drain pan with multi-directional drainage ports for flexible installation.
• Optimized Performance: Specifically calibrated for York and Johnson Controls equipment to maintain AHRI-matched system efficiency.

Is this coil compatible with R-410A systems?
Yes, the S1-373-27868-402 is designed for modern high-pressure refrigerants, though a TXV or orifice change may be required depending on the specific BTU rating of your outdoor unit.

Does this unit come with a factory-installed expansion valve?
This indoor coil typically requires the transfer or replacement of the thermal expansion valve (TXV) or piston, as it is designed for multiple tonnage applications.

Will this fit in a 17-inch wide furnace plenum?
This model is standard for 17.5-inch cabinets; always verify internal clearance and transition requirements before brazing into the system.
