There are some differences, however. When replacing an R-22 system with R-422B, only charge the system to 95 percent of the R22 level. The refrigerant charge may need to be adjusted to deliver its best performance. Also check the superheat, following the dew point on the pressure/temperature (P/T) chart.

What is R22 Refrigerant? R22 refrigerant is a colorless gas known chemically as hydrochlorofluorocarbon 22 (HCFC-22) and is one of several refrigerants that goes by the brand name “Freon.” It's used in a wide variety of applications, including central HVAC, commercial refrigeration equipment and automotive AC systems.

HCFC refrigerants are being phased out from use. This refrigerant phase out chart outlines what's already been halted and what's scheduled in the coming years.
In this chart, we compare R32 vs R290 vs R134a vs R12 refrigerant, so you have all the basic details when conducting research for repairs and retrofitting.
You’d be surprised, it’s still sold pretty much everywhere. just got really expensive recently. My main concern is the POE and MO currently used in various R22 systems.
