The Bard 5062-074BX is an OEM coated evaporator coil shipped boxed for service replacement, built to restore proper indoor heat transfer and moisture removal when a coil is leaking, restricted, or badly corroded. In Bard wall-mount and packaged systems, the evaporator coil is the primary cooling coil in the airstream, so replacing it with the correct factory part helps maintain designed capacity, airflow performance, and refrigerant metering operation. Because evaporator coils are model and revision specific, match 5062-074BX to your unit data plate and the Bard parts list before ordering, and plan for standard refrigeration best practices like nitrogen purging while brazing, replacing the filter drier as needed, evacuating to a deep vacuum, and charging to Bard specifications.
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.
