Hello.

Does anyone know if there is a way to use R410A or any other available (widely available enough) non-ozone depleting refrigerant in a typical R22 9,000 BTU compressor?

I'm not sure about propane because there seems to be a safety issue, and refrigeration store don't sell it here.

I am new here and just learning about air conditioning and refrigeration, and am unfortunately experiencing difficulty finding the information that I need.

Thank you for your time.
