No the accumulater was not replaced

System needs to be flushed oils are not compatiable. Acc must be replaced as well as orfice tube. 134A not a drop in replacement. Would take to professional AC not a DIY job

No way R12 oil will not be picked up and flow through sysytm. Consult with a shop that does AC
