Thank you for putting this video together and for an explanation that does not involve 2 to 3 thousand dollars in equipment

Just some advice to help out. You don't have to check for bubbles if you're holding pressure. A faster more accurate method would to use a digital pressure gauge that monitors in points tenths and 100 of a pound. Also using a larger vacuum hose after you remove the valve stem will save you a lot of time. Used in tandem with the digital pressure gauge will really save you a lot more time.

NIce video; easy to see & you explain it well. I've heard of people soldering refrigerant joints rather than brazing. Have you had trouble with them lasting ?

Hey very good video how much cubic ft is that nitrogen cylinder and approximately how much ac units can u test with that cylinder of nitrogen

Is 14 minutes holding nitrogen a 💯 you dont have a leak?

Agree to disagree.. bleeding is an insurance to avoid air at all cost!! Little risky in my opinion! Thank you for the response 😊

[Samlol_drrich]

Great. Thanks. Is that the same tank you use when you brazed the linesets?

What's the capacity of you nitrogen cylinder tank?

[juansantiago]

Sorry, but it appears you did not bleed your lines before releasing the nitrogen to the system..
