In the US when were R-22 and R-142b phased out?

Explanation:
R-22 and R-142b are ozone-depleting refrigerants (HCFCs), and their use in the U.S. has been tightly restricted under EPA rules that align with the Montreal Protocol. The phaseout happened in two stages: a ban on using these substances in new equipment around 2010, followed by stopping production and import for servicing by 2020. That means for servicing and new equipment, the practical end date is 2020. Up to that point, systems could be serviced with reclaimed or recycled refrigerants, but new production and import of these substances were halted by 2020. So 2020 is the date that reflects the full phaseout timeline across the United States.
