Your vacuum series, is absolutely amazing 😍

Well done you are good teacher

[@love2hvac]

Thank you

Excellent vid friend...

Thank you

Thank you Mr.Ty in the length of refrigerant lines in every 1 foot should have to add 2 oz? Thanks. 🌹

Great question, here is a great explanation for that www.acservicetech.com/refrigerant-weights

Why use Nitrogen prior to vacuuming it out?

[@love2hvac]

To sweep the water vapor out. The more water vapor pushes out, the leads that will end up in the vacuum pump oil and the faster the vacuum will be.

I have a real question to pick everyones brain If youre pulling a vac on a carrier system (basic ones) Where the cond is piston(liquid line port)and the indoor is txv and the drier is installed at the liquid line port.. Is it better to put the trublue hose still at the suction line port and micron gauge at the liquid port? Or the trublue at the liquid line and micron at the suction meaning should you start the evacuation with wheres more restriction is at first or should it be let handled last?

In the title, you indicate p16 example 4 standard manifold. Is that referencing a text book? If so, can you name it and can I get a copy? Thanks

[@love2hvac]

It's just how I'm labeling the series. I record them sequential so one lesson builds upon the next. One day I may make a book that references the videos.

I hope you don't get paid to teach HVAC you can't even pull a vaccum right. You NEVER put your micron guage on your pump. A vaccum pump produces 20 microns of deep vaccum to allow it to pull down to 500 microns or below. You want to place your micron guage at the furthest point so you know that you pulled the entire system down to 500 or less microns. Get a T take out the core and put it on the suction or liquid side if you have to just DONT PUT IT ON YOUR VACCUM PUMP! All your doing is giving yourself a false reading and checking how deep your vaccum is at your vaccum pump...... Dosent make much sense does it 🤣 I'm a commercial hvac tech and they teach that in the apprenticeship class during your first year 🤣 ask any school even online ones or any commercial tech and they would laugh at you for putting it on your pump.

I agree with what your saying even though I disagree with the aggressive delivery. Now that we agree the micron guage should not be at the pump would you allow me to explain this video? 1st this video is part of a series about vacuum that goes deeper than any HVAC instructor has dared to go starting at HVAC 135 understanding atmospheric pressure all the way to HVAC 152 the review of vacuum. I think video havc 152 vacuum pt 19 you might like and you will see I say some of the very things you are passionate about. 2nd if you would take the time to watch this entire you would see the entire purpose is proving why we do not want to have the micron guage at the pump. This video shows a method that is commonly used but if you keep watching you will see a second micron gauge installed at the evaporator coil far from the pumps and I prove the very point your trying to make. I show the micron at the evapo coil far from the pump and the microns at the pump so everyone can see the difference. Everyone can see how big the difference is 3rd if you just watch at the 5:30 mark, the micron guage at the pump shows 500 microns but at the evaporator coil far from the pump is at 1114 microns. That is quite a difference designed to show why we don't want the micron guage at the pump. 4th I agree the valve cores should be removed, and I explain that in this video, previous videos and videos after this where we do the comparison showing how much faster it is with the valve cores removed and using vacuum rated 1/2 hoses without using a manifold at all. I could be wrong but it seems to me we are on the same page. The only difference is you chose to address the video with a snide comment before even watching the whole thing to see what it was about. If we are going to be promoting the importance of good vacuum techniques, let's work together to lead people to a better way. I feel this is much more productive than personal jabs. If you would like to discuss this topic further please send me an email with your number and I will give you a call and we can have a professional conversation. I will be happy to share my credentials, qualifications and experience if that is important to you. Have a great night and keep things positive. It's just too hot out here to be arguing on something we already agree with.

Your comment was funny , you guys are saying the same thing 👍🏽

[@NeighborhoodDada]

@@love2hvacthis guy obviously didn’t watch or listen to the video because he would have heard you explain that we don’t typically put the gauge on the pump
