In case anyone is still interested.....
Apparently there was a meeting on Monday at the AC company and then people showed up here with some new equipment. Things were better but not great.. could not easily pull below 700 microns. In the afternoon they came back with a new hose that was the vacuum type. Big improvement - pulled to 450 microns.
I pointed out that the new hose brought this morning wasn't the vacuum type. If you want to pull a good vacuum things have to be correct and in good condition. The last? problem is when turning off the ball valve to hold the vacuum - it adds 100 microns.
Anyway things are getting better.
