what happend was, i went to an appliace and started talking to the owner. i figured since he owns the place and works on some of the stuff he might know a little about refrigeration. he started telling me a bunch of crap id never heard before, like having different gauges for each refrigerant, never braze with nitrogen or itll blow sky hi,and you cant make a living working on heat pumps and such in a town of only 80.000 etc. i guess some people will try to tell you anything to make themselves look good. until you know better.

I was over at the local parts counter the other day and I saw some new guages that were for R-22 and R410A. Counter guy said manufacturers are saying you can do both with these guages without any problems> That sound right? At some point you are going to be mixing. I dunno.
