Does Freon R-22 hurt the environment?
Scientists have associated ozone depletion with potential health risks, and many countries, including the United States, are taking steps to reverse the trend. The culprit in traditional refrigerants (R-12 and R-22) is a chlorine atom, which reacts with ozone in the upper atmosphere and destroys it. R-410A, chemically known as an HFC (hydrofluorocarbon), contains no chlorine and will not damage the ozone layer.
