Howdy folks,
AC blowing hot as summer begins rearing its ugly head. I had a local mechanic vacuum out the refrigerant (r134a) so I could investigate, and I discovered the black death had struck. I will be replacing everything I need to but I have one concern: The mechanic said it will be fine to put the old refrigerant back into the system once I get everything replaced, but I don't want all my work to be for nothing by putting contaminated refrigerant into the new clean system. Would a proper AC vacuum pump system at a mechanic be able to filter out the contaminants caused by the black death, or should I just put fresh refrigerant in?
