I think you'll be able to buy R22 for at least another 6 (and probably another 11+) years, at which point that system will be 20 (or 25+) years old and replacing it won't be viewed as out of the ordinary, nor provide a particular bonanza of income/profits to HVAC companies.

A lot of people in various countries just charge R-22 and R-12 systems with purified propane. (or regular propane too)
