UAC AK 2220 A/C Compressor Replacement Service Kit

The UAC AK 2220 is an A/C compressor replacement service kit — an ancillary kit that bundles the supporting components needed when replacing an air conditioning compressor. Replacing the compressor alone without renewing wear items like the accumulator/drier, expansion valve, and seals is a leading cause of repeat failures, making a complete service kit an essential part of a proper A/C system repair.
