What is the only refrigerant that is freon?
Technically, the only actual Freon was R-11, which was one of the most common chlorofluorocarbon (CFM) fluids in use up until 1996, when CFM was banned in the United States due to its impact on the ozone. Subsequently, automakers replaced R-11 with the non-CFM fluid R-134A, which scientists developed as a somewhat eco-friendlier though still chemically-laden refrigerant. In 2013, however, the auto industry initiated another change, this time to HFO-1234yf, which is believed to be the most environmentally sound refrigerant yet conceived. With this latest development, cars pose a smaller environmental threat in cases where the refrigerant leaks.
