Why: HCFC-22 was phased out in steps. Since 2020 there has been no new production or import of R-22. EPA says some HCFC uses continue, such as servicing existing equipment. All HCFCs end in 2030.

Huh, didn't know that: EPA required HCFC use to be at least 99.5 percent below baseline levels by 2020.
