Is r22 refrigerant legal

As of January 1, 2020, the production and import of R-22 refrigerant have been banned in the United States due to its ozone-depleting properties. However, R-22 can still be legally used in existing systems, and reclaimed R-22 can be purchased and used for maintenance and repairs. Users are encouraged to transition to more environmentally friendly alternatives. Always check local regulations, as they may vary by region.
