The Bard 917-0403BX coil assembly boxed-service is an OEM replacement refrigeration coil designed to restore proper heat transfer and airflow performance in compatible Bard wall-mount HVAC equipment. This coil assembly is used in the sealed refrigeration circuit, so correct model and serial matching is critical before ordering, and installation typically involves refrigerant recovery, proper brazing practices, evacuation, and weighing in the factory-specified charge. If your unit is showing symptoms like poor cooling, icing, oil staining at the coil, or confirmed leaks, replacing with the Bard 917-0403BX helps bring the system back to Bard specifications while maintaining fit, tubing alignment, and serviceability expected from genuine Bard parts.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
