This is Turtle.
i have a Son in law that was working for Dupont at the time and he and I was
talking to one of there chemical engineers at a social gathering and he was
telling the R-22 did show some signs of some break down on or about 164 years.
They have ways of projecting time of freon break down and r-22 does break down a
little at 164 years. He did say that if it would be the case. You should change
out the R-22 every 164 years in any equipment that you may have.
So we should recommend changing the Freon 22 out every 164 years !
