During a system cleanup, changing the oil in a hermetic compressor:

Explanation:
Oil inside a hermetic compressor is part of a sealed lubrication system and isn’t changed during a routine system cleanup. Draining and replacing that oil can upset the lubricating balance, alter viscosity, and remove additives that protect the bearings, which can lead to inadequate lubrication and potential compressor damage. The cleanup process is focused on clearing the refrigerant circuit of contaminants, replacing filters and dryers, and ensuring proper evacuation and recharge. Oil changes are only considered in special situations, such as confirmed oil contamination or when replacing the compressor. So, changing the oil during a system cleanup is not suggested.
