Recently my wifes Saturn compressor self destructed. A mechanic she knows replaced it and a couple of other components for her and re-charged. Since then the system is noticeably less efficient at cooling the car than before. I know nothing about AC and this is not a Mercedes so I'm posting it here asking a general question. I suspect that he may not have charged it back to full capacity. Could that cause it to cool inadequately while otherwise apparently working normall?
