I don't think CFCs are the ones that cause global warming. They deplete the ozone layer, but recently, the ozone's been healing. Global warming is a bigger issue though...b/c it's hard to find a replacement for fossil fuels that release carbon dioxide. Also, it's very hard to reverse this. The temperature has risen some four degrees.
Anyways, CFCs aren't only in ACs. They're also in refrigerators. It's good CFC isn't used anymore...
