It’s not that R-22 is not available (it is - at $825 per jug… that’s $225 for the refrigerant and $600 for the UN)
We used Duracool R-290 for a while, and then moved to R-424 (also marketed as “Acme Cool 77”. They were good, but voided the compressor warranties (generally 10 years), and required evacuating and nitrogen purging the system before charging. We calculated for a 20% loss in cooling capacity.
The R-422 seems to work at 100% in an R-22 system. I still have to purge the system before charging, but otherwise it’s a drop in replacement (no change in lubricants). $225 per jug, too!
It also makes my trips to London, Ontario purely personal (visiting a friend sons), and I don’t have to pick up the jugs of R-290.
