Master Class on Vacuum & Evacuation (whole presentation)

Instead of the 4 separate videos on Vacuum & Evacuation, we've combined them into one so you can grab a beer and some popcorn and enjoy 1 hour and 15 minutes of Jim Bergmann love.

I’m glad to hear you mentioned using copper lines as vacuum hose because that’s exactly what my dad taught me when I was 12 years old and that was 40 years ago. And my dad was taught that when he was a young man so this is nothing new it is old technology taught by the masters who died long ago. Thank you Jim Bergman for putting in all your hard time and effort to re-educate a trade that lost its education decades ago.

Not all heros wear capes, this man a living legend.

He actually makes watching HVAC training exciting.

I’m mostly learning auto systems right now but most of the car air videos are crap. This is where you go to really learn stuff. Very good, I may have to watch it two or three times but excellent stuff. Gets your head screwed on straight when it comes to vacuums and evacuating systems.

What a public service to HVAC & MVAC professionals 👏🏽👏🏽👏🏽👏🏽. Thank you Jim! You are a wealth of knowledge and we all benefit from this and thank you 🙏🏾

"The more I learn the less I know!" Been digesting this for a couple of weeks now, very nice job Jim. Thanks so much for putting this together!

[@Pennconst101]

With these hoses you could do a legitimate Triple evacuation every time in less than an hour. Outstanding

[@jrm163]

Very good information, Jim! You know both theory and practice!

[@dacoelec]

One of the smartest thing I've done in equipment procurement was purchasing a two hose Tru Blu kit! Unbelievable what it does to your evac time and makes a great carry case for all of your adaptors and fittings!

[@mrcrux213]

Another very good explanation in a infomercial by one of the best in the industry Mr Jim Bergman. 👏👏👏👌😉

[@bradenjohnson3830]

Very informative! Thanks for combining them for us.

[@chuckdearruda6271]

Great video, thanks Jim!

[@waynepesuit9520]

Great presentation however showing the slides full screen would really improve their clarity. Thanks

[@chuckdearruda6271]

Really nice! Thanks Jim!

[@hozerhvac4406]

What a great lesson and presentation Jim 👍

[@rojohe]

Excellent video as usual. That said, I found one small discrepancy that would benefit from some clarification. At approx.

[@marksmith6259]

@ 39 Minutes, I totally agree with him on the oil, but would like to say one thing, if you go from job to job just installing small splits and relatevely clean systems (no brazing) short pipe runs the pump definitely doesn't need to be changed every time, however I have pulled a system that I changed over 5 times in a single pull down...

[@jrm163]

Another thought, based on the theory, we should probably take off those OEM small adapter(s) or fittings on the vacuum pumps, and use a bigger one that matches a big hose, which further matches the pump’s CFM. this should further improve efficiency!

[@satakal]

high quality stuff. Thank you.

I've been a service tech for 16 years , nobody ever told me to loosen the ballast when you start the pump and close the ballast around 2000 microns for a deeper vac . Education
