About R-422B
The appeal of R-422B is what you do not have to do: no flush, no oil change, no wondering whether the old charge and a new lubricant will get along. It is a blend, so liquid charging applies and the pressure–temperature relationship is its own, not R-22's. Re-check the expansion device and the superheat after a changeover.
