I am glad you admit to
''''. Even though I know that pressure and R22 is the best way to find leaks'''' Rollguy
If a person wants to try nitrogen and soap .. great... but if they want the best check... read SNIFF ..... and for the sniffer to cover the entire AC system in one move.... then they know what to do...

I don't think you get it. I think you live in a ivory tower. If the shops, the professional, do not use it then it is either not practical, expensive or cumbersome to use R22. You don't understand the law of diminishing return. R22 may catch 0.1% of the leak but if the shop can make do with N2 and soap water to catch the other 99.9% then why bother? If you are happy with using R22 then so be it. It does not mean everyone has to do it or follow you. Next subject.
