• Subcooling Heat Exchanger

Bard part number 5204-001 is an OEM subcooling heat exchanger used in the sealed refrigeration circuit on select Bard wall-mounted package air conditioners (listed as a functional component in the W17L2 and W18L2 replacement parts manual). This component helps stabilize liquid refrigerant delivery by improving subcooling, which supports proper metering performance and dependable cooling under changing load conditions. Because it is a refrigerant-carrying assembly, replacement should be handled by a qualified HVAC technician using proper recovery, evacuation, and leak-check procedures, and you should confirm model and serial compatibility before ordering to ensure correct fit and connections.
