I've heard that they're phasing out the old A/C Refrigerant in favor of a new, more environmentally friendly version.

That’s right. As of January 2010, cooling system manufacturers can no longer make equipment that uses R-22, commonly known as Freon. R-22 has been found to damage the Earth’s ozone layer, which is a key factor involved in global warming. By 2020, R-22 will no longer be produced. The coolant that has replaced R-22 is known as R-410A, which was developed by the Allied signal company in 1991. Several companies have since trademarked their own version of R-410A, including Carrier (Puron®), Honeywell (Genetron® AZ20) and Dupont (Suva® 410A). Years of commercial use and testing have proven that, in addition to being more environmentally friendly, R-410A is superior in performance and energy efficiency to Freon.
