Ah, well. All the numbers. 12 went to 134a (with oil change,
and new metering device). The newer equipment is designed
22 is going to, something else. Either a drop in blend, or
maybe the equipment will die by the time it's needed.
502, couple replacements. 408a comes to mind, and the new
404a with new oil and new equipment.
It's all big blur of numbers.
