  1. Your article should mention that all refrigerant should be reclaimed and recycled by an auto shop that can do it legally. Venting R12 refrigerant can result in a $10,000 fine. It is illegal and it depletes the ozone layer. The fine for synthetic greenhouse gasses, like R134a is even greater, $50,000, because they contribute to global climate change more than carbon dioxide, by a factor of 1,000.
