Mike and I are kicking around whether or not there is a good alternative refrigerant for R-22 in A/C service ??
ICOR Nu22-B came up - is there any info you learned folk can pass on?
Past use, oil change info, capacity loss / gain etc. would be appreciated - or is is a buch of ' snake oil ' ?? Perhaps this discussion has already gone around the bases ??
Thanking you in advance - - - - -
