Don't drink the Kool-Aid. DuPont owned the right to "FREON' R-12. Then the ozone scare. But low and behold DuPont comes up with the environmentally safe R-134A. Difference? R-12 sold for 19 -49 cents a can, The new and improved R-134A sold for like 15.00 can when it came out. Hummmmm? They then came out and said, one volcanic eruption did more damage to our Ozone than a 1000 pounds of R-12 being released every day for a 1000 years!
