In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
On a Rudd system with a scroll compressor, my neighbor shot some 22 in and it helped with the cooling problem. It was last charged 9 yrs.ago so I'm not that concerned with it leaking, I'm concerned that the liquid line does not stay cold for more than 5 minutes. Could that be a symptom of an overcharge? Not sure if it did that before, it cools better now but does not seem to draw down as fast as it did before.
