I went to my local supply house looking for a micron gauge the first counter guy said micron what? & walked over to the next guy to ask about it.
Now the somewhat disturbing but not surprising part, The next counter guy said "not on this side of town" (culver city serving most of west l.a)
I did eventually find a supco vg64 at another supplier hidden on the bottom shelf with a bunch of crap over it.
Is this a normal thing throughout the country that the majority of a/c guys are hacks?
