like all this. but my problem is nobody is teaching how to pull a vacuum on these ac systems. everybody says 30 to 45 minutes and my 10k machine makes the world perfect. i use a micron gauge and if you do everything like oil balance ,proper freon charge and get down under 500 micron with no more than a rise of 1000 , i like to stay under those numbers myself and i can achieve low microns with triple nitrogen purge and sometimes a 12hr vac pull. dont have to go 12hrs but sometimes it is needed. thats the only thing i see is not happening. everybody will say been doin that 45 min for 20 years wont even attempt to try a micron gauge.whats ur thought
@RATCHETMAN1001 90% of techs are going to use an AC machine from Robin air or similar. They are going to press vacuum, set the timer, and that's it. A micron gauge is great. More accurate, more of a guarantee that you have forced evaporation of any moisture in the system. But bluntly, it's a better way, an added cost, a longer vacuum time... for what? We are servicing thousands of cars a day without issue using what we have. I have seen a couple cars in my career with evidence of excessive moisture in the system. One was a body shop car that had the lines open for a month and it just needed a longer vacuum time and a desiccant replacement. The other was parts store can recharged multiple times and just a vacuum and recharge fixed it. So yeah, sounds like you are doing an amazing and thorough job. Very nice. But from a business perspective, not more profitable, from a typical customer perspective, taking longer and not objectively providing any more effective service. With that being said, I appreciate your attention to detail.
