Does an air conditioner contain chlorofluorocarbons?

Answer 1

Perhaps yes or perhaps no. Don't mean to be a wise guy, but in the strict sense, chlorofluorocarbon refrigerants have no hydrogen in them. They have only chlorine, fluorine and carbon. These refrigerants have been demostrated to be harmful to the ozone layer, though, and have been banned to a large extent by treaty. Only a few of the "old style" units remain in use. You may or may not have one, and that's why the "yes or no" answer. There used to be lots of chlorofluorocarbon (CFC) refrigerants, but now we have what are called HCFCs to replace them. The HCFCs are a lot less damaging to the ozone layer, and, though they aren't as effective as refrigerants, they are less harmful to the environment. HCFCs are CFCs with a bit of hydrogen in them. We're not splitting hairs here, but it is important to keep our facts straight. Wikipedia has a short blurb on CFCs and HCFCs, and it is tucked inside the post on haloalkanes. No sweat. Just surf on over and read just that section. It's not rocket science. A link is provided.

Answer 2

Older air conditioners may have contained chlorofluorocarbons (CFCs), but most modern air conditioners use more environmentally friendly refrigerants like hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs). It is important to recycle and properly dispose of old air conditioners to prevent the release of harmful CFCs into the atmosphere.
