What type of AC refrigerant might be used in a 30yr old (GE brand) residential system? R22..R12? Do newer systems use R134?
Thanks,

What does the condenser say?
Thirty year old unit may take R500.
Almost certainly R-22.
No, not your typical split system. Still R-22 or (ugh) Puron.
Thirty years ago, essentially all AC systems (residential or commercial) used R-22. Please let us know what you're trying to do. Are you a service tech?
R-134A was not used in any signifigant ammounts till 1993 or 1994.
