Bundling the critical ancillary parts into one convenient package, this kit helps ensure the repaired system operates reliably and extends the life of the new compressor.

Why Replace These Components Together?

When an A/C compressor fails, debris and contaminants can travel throughout the system. Replacing the expansion valve, filter drier, seals, and oil at the same time as the compressor is critical to preventing repeat failures and protecting your investment. Four Seasons installer kits are assembled to simplify this process and ensure nothing is overlooked during the repair.
