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

HVAC Refrigerant
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. -- Christopher A.
