Reusing Refrigerant After the Black Death?

[redrangerbluemiata]

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?

most ac recovery systems have filtration on them already

What's the black death?

What's the black death?

Bubonic plague.

Caused by poor digestion and sin.

Trust the Science.

What's the black death?

Catastrophic AC compressor failure which contaminates the whole AC system. Requires a complete replacement of every AC component except the evaporator. It's a well documented Ford issue.

Not really a Ford issue, it is a A/C compressor issue.

Either they make cold air or blackness and dispair.

A modern reclaiming machine will filter out whatever impurities there are in the freon.

It's not a "Ford issue", it's universal to anything with a compressor. Most of the components can be flushed with solvent- at least all the lines can if you're concerned about trapped particles.
