I had asked in the general questions thread about the AC in my F150, I'd recharged it only to find the high side valve was leaking.
I couldn't get it booked into the shop before July 1 and realized last weekend that all the R134 had leaked out the bad valve already, and that this handy thread was back up for reference.
So I replaced the valve ($5 at auto zone), dryer and o rings ($40 from Napa), pulled -26psi of vacuum on a Harbor Freight air powered vac pump, left it for a bit and filled it up again. It's been running like a champ for maybe $120 worth of parts including the gauge set I bought and 2 cans of wasted refrigerant. A great result.
The price of R134 seems to vary a lot between stores and brands, the cheapest stuff I found was at Harbor Freight, they had a decent selection of auto AC tools as well and I was impressed by the air powered vacuum pump. It did take a lot of air to pull the vacuum >20psi, my small 110v 2hp compressor couldn't hold it past 15.
i must be misunderstanding something. how on earth can you get < -14.7psig? car at the bottom of the ocean?

well, autozone has the AC gauge set and vacuum pump in their loan-a-tool program, so if you want to do it yourself you should be able to at least verify that it holds vacuum before you take it to the shop
but you could also swap the drier and charge it up yourself too, if you wanted
