York S1-363-93521-704 Heat Exchanger

The York S1-363-93521-704 Heat Exchanger is an essential OEM replacement component engineered for high-efficiency thermal transfer in residential and light commercial HVAC systems. This 4-cell furnace heat exchanger is constructed from industrial-grade, heavy-duty steel to withstand the rigorous demands of repeated thermal cycling and prevent premature stress cracking. Designed specifically for York heating equipment, this unit ensures optimized airflow and maximum BTU transfer, maintaining system performance while reducing fuel consumption. As a critical pressure-containment part, this York OEM heat exchanger maintains structural integrity under high-operating temperatures and prevents combustion gases from infiltrating the supply air stream. For contractors performing a furnace heat exchanger replacement, this 4-tube assembly provides an exact fit, reducing labor time during teardown and reassembly of the burner plate and collector box. Utilizing genuine York HVAC parts ensures the unit remains within original manufacturer specifications for safety and efficiency.

Key Benefits:

• Precision Thermal Control: The 4-cell design maximizes surface area for superior heat transfer efficiency.
• Heavy-Duty Construction: Manufactured with robust, corrosion-resistant materials for industrial-grade durability.
• Direct OEM Fit: Ensures seamless compatibility with the York S1-363-93521-704 specification, eliminating field modifications.
• Engineered Safety: Provides a tight seal between the combustion chamber and ventilation air to prevent CO leaks.
• Optimized Performance: Engineered to restore factory-rated AFUE ratings and reduce system short-cycling.

Common Questions:

What are the signs of a cracked heat exchanger in a York furnace?
Technicians should look for soot buildup on the 4-cell heat exchanger, irregular flame patterns (flame rollout), or the presence of moisture/condensation in the combustion area. If the furnace trips the high-limit switch frequently, the assembly should be inspected for internal obstructions or structural failure.

Is the S1-363-93521-704 compatible with other brands?
While this is a York OEM replacement part, it is also frequently used in certain Coleman and Evcon residential gas furnaces sharing the same chassis design. Always verify the model number on the unit’s rating plate before installation.

What is required for a professional installation?
A complete replacement typically involves removing the inducer motor, manifold burner assembly, and collector box. It is highly recommended to replace the associated gaskets and high-temperature seals during the process to ensure a gas-tight fit.
