Certain types of Freon are. Those types are no longer used in new air
conditioning or refrigeration systems. Older systems will still have
them,
but you can't replace lost fluid if you have a leak.

Where did you hear that? That must have been nonexistium that the AC
technician put in my AC at home this spring. G

The old stuff is still available, but it costs more than the new stuff, and
must be used by licensed tecs, and must be pumped out and recovered when
conditions demand that it be removed from the system. I think I heard that
the old stuff is not being manufactured anymore, but that the existing
stockpiles will last for a few more years, but I'm not at all sure about
that.
