Have a quick question.
My boss goes away to a manufacturer's school.
Comes back proclaiming that we have to be EPA certified to work with R-410A.
I humor him, and let him babble on.
Now I know that some supply houses are selling training classes to get tech's familiar with the pressures and a refresher on techniques. Also to let them know that now evacuating to 500 microns is now an important thing, as it always has been.
My question is.
Is there some validity to his paranoia?
I figured that I would ask people who know what is going on.
