One of them is already in this thread....and I expect the other one to arrive any minute... LOL
It is not you that I am referring to...
that tool kit you recommend IS two stage... thumbs up...

This part of his statement " cheap VP is good enough. You don't need the best vacuum for A/C to work. I used to use the Venturi VP ( $12 ) pump with a compressor to do A/C work at home. never failed. "

NO ONE who knows about the physics of taking the moisture out of and AC system agrees that a ' cheap' VENTURI VP ( OR EVEN AN Expensive one ) will pull enough vacuum to be effective....

OK. It is me who wrote the Venturi pump. If it does not work then it will not be manufactured by Harbor Freight or others. Is it ideal? No. Does it work? YES. There is NO conspirator or conspiracy theory here. Please do not elevate yourself. You may fall and fall hard.

' does work or will not be manufactured by HF ' ...LOL
the Venturi type of pump does NOT WORK WELL ENOUGH to properly evacuate an AC unit...
it can make a vacuum for less ' needy ' uses.... but drawing enough vacuum to BOIL out the moisture is in a different category than that...

Last post here.

"does NOT WORK WELL ENOUGH" = WORK

"to BOIL out the moisture" = receiver/drier does the job

It is not a perfect world. A/C is not rocket science, please do not convince others that it is. Please don't elevate yourself either.

LOL... where do you get this reference to ' perfect world' ?
there are CHARTS which show for any particular temperature and barometric pressure ( and perhaps mixed with oil ) HOW much vacuum must be pulled to boil that mixture...
it has nothing to do with ME...
all this stuff can be looked up...
if you actually wanted to know and understand it...

and another thing.. which I have said MANY TIMES..

there is a difference in what it is fine for you to do TO YOUR OWN CAR...
as compared to what it is ETHICAL to recommend to others.. many of which have not or can not do their own research into AC fixing..
therefor conservative and slam dunk reliable information should be a priority for THEM...

For the record... literally.... WHunter posted with regards to the ' venturi pump ' acceptability .... NOT... is the conclusion.. IF you did not understand the physics information available everywhere..

This is why I put you into the conspiracy theorist category... as if " I " was trying to sell " PERFECT WORLD" philosophy concerning AC theory.. this is easily accessed information all over the industry...

"""Originally Posted by ah-kay Last post here.....

the idea that""" the receiver / dryer does the job of taking out the moisture"""" is ABSOLUTELY WRONG.... it is made to take out what you can not get from using a vacuum pump to take out.. it is of limited CAPACITY ..
and EVEN OPENING ITS CAPS before you are about to install it is WARNED AGAINST IN THE MB AC MANUAL...
and everywhere else AC is discussed on the web, in TEXT books, just everywhere...
