York S1-029-22156-000 Filter Drier

The York S1-029-22156-000 Filter Drier is a critical liquid line filter dryer designed for high-efficiency moisture and contaminant removal in residential and commercial HVAC units. Engineered as a high-performance filter drier strainer, this component utilizes a desiccant core to adsorb system moisture and neutralize harmful acids created by hydrolysis. By protecting the expansion valve and compressor from debris like copper shavings or brazing flux, it ensures refrigerant flow optimization and prevents the formation of ice or sludge within the capillary tubes. This OEM replacement part is specifically sized at 1 x 4-1/4 inches with an integrated spring, making it a drop-in solution for York model AC024M1021A and compatible 410A refrigeration systems. For any veteran technician, maintaining a clean refrigeration circuit is essential; replacing the drier during every system opening is standard practice to prevent HVAC compressor failure and ensure the long-term stability of synthetic polyolester (POE) oils.

Key Benefits

• Advanced Desiccant Technology: Effectively adsorbs liquid moisture and prevents acid buildup in high-pressure liquid lines.
• Integrated Strainer & Spring: Features a robust 1" x 4-1/4" design with a spring mechanism to ensure proper seating and particle filtration.
• OEM Compatibility: Precision-engineered for York AC024M1021A and various Johnson Controls equipment.
• System Contamination Protection: Traps solid contaminants such as carbon and flux to protect sensitive metering devices.

Common Questions

When should this filter drier be replaced?
Standard field procedure requires replacing the filter drier whenever the sealed system is breached for repairs, or if a significant pressure drop is detected across the device.

Is this compatible with R-410A systems?
Yes, this drier is designed to handle the hygroscopic nature of POE oils used in modern R-410A circuits, ensuring maximum moisture retention.

What does the internal spring do?
The spring provides mechanical tension to keep the internal strainer and desiccant held firmly in place, preventing bypass and ensuring all refrigerant passes through the filtration media.
