How to Evacuate an AC system, Full Vacuum Procedure

Great video, Bryan. So many good tips!

So much information lol. Thanks👍

On a new minisplit install. Will flushing the copper lines with 400 psi nitrogen remove ash, if any, leftover from the nitrogen brazing.

Good video. Analogy with small port and toll both is a bad analogy because fluds accelerate through orifices to match the volume through the rest of the line...not so with toll booths. Better proof is to blow air through a drinking straw and a gsrden hose. Waaay harder to blow through a long hose than a short straw even though straw is way smaller.

I wish I could get people to follow these procedures at my job it’s insane how many guys are doing these simple steps wrong in the field !

Completely clear, thank you

Napakahusay at detalyado nang iyong paliwanag👍

I’m currently going to school, your videos and a couple of other channels are really helping me out understand the information apart from the lectures and in class labs 👍💯

When pulling a vaccum I noticed my oil level goes up to the top of the sight glass even though when it's off it's a the oil fill level...is this normal?

this is not for people who dont know about this subject evidently

For everything he says he never achieved below 300 Microns. Hmm!!!

Decades using a manifold set and now this guy says they don't work as well?

Core removal tools are no good. You can test this by blowing into one side of core removal tool while having the shaft is back in place. Air is entering system.

Wow info overload 😵‍💫 great video if you want lots of info you don't really "need" to do the 2min job to hook up . Really smart guy though .

As times have changed. Interesting, thanks. 45 years ago, 29.95 was the goal.

Wow! By far the best video on this subject, thank you!!

Even with a wider hose doesn’t it still have to go through the small hole anyways just like it would with a skinnier hose?

New to the trade love your videos ❤

Bryan you are the man. Your delivery and knowledge on this subject of HVAC is second to none. I am a big DIY guy who has done most DIY stuff except AC refrigerant type work. Probably never will but at least I know what it’s all about. I understand everything you say and it is clear you have great knowledge and passion for this subject. Great delivery. Thanks
