York S1-373-39504-003 Conversion Kit

When you are performing a field upgrade on legacy York hardware, the York S1-373-39504-003 GEN2 Compressor Conversion Kit is the essential OEM solution for transitioning from GEN1 to GEN2 compressor technology. This kit is engineered to modernize existing residential air conditioning and heat pump units, ensuring seamless integration with original line sets and electrical configurations. As a veteran-grade retrofit package, it eliminates the guesswork inherent in compressor replacement and HVAC system efficiency upgrades. By utilizing this genuine York replacement part, technicians can achieve optimal refrigerant flow and compression cycles without modifying the entire condenser chassis.

The kit includes high-precision components designed to maintain system equilibrium while improving cooling reliability. For contractors, this means a significant reduction in labor hours compared to sourcing individual fittings. This HVAC conversion kit is critical for revitalizing older units that require the superior mechanical tolerance of contemporary GEN2 HVAC technology. Proper installation ensures that the compressor operates within manufacturer-specified parameters, maximizing BTU output and minimizing operational vibrations.

• Ensures direct mechanical compatibility when upgrading from Generation 1 compressors.
• Reduces on-site modifications with a complete assembly of necessary adapters and fittings.
• Maintains the structural integrity of York residential air conditioners and heat pumps.
• Optimizes system performance by aligning legacy hardware with modern GEN2 specifications.
• Streamlines the service and repair workflow for professional technicians.

Is this kit compatible with R-22 to R-410A refrigerant transitions?
This kit focuses on the mechanical conversion from GEN1 to GEN2 compressors. While it supports more efficient motor and valve technology, always verify that your specific compressor model and expansion devices (TXV/piston) are rated for the lubricant and pressure requirements of the refrigerant being used.

Does this kit include the compressor itself?
The S1-373-39504-003 is a conversion hardware and component kit. It provides the essential adapters, wiring, or plumbing required to mount and connect a newer generation compressor to an older unit frame; the compressor may need to be ordered separately depending on the package configuration.

What field tools are required for this installation?
Standard HVAC recovery equipment, brazing tools (oxy-acetylene), and vacuum pumps are necessary. Because this involves opening the refrigeration circuit, the use of nitrogen during brazing is required to prevent oxidation inside the new GEN2 components.
