Recommended values for vacuuming are as follows. 20-30 minutes for automobile,SUV,Small truck 30-45 minutes for Mid-Size,straight,local delivery 60-90 over the road w/Sleeper class 7 and 8 90 or more minutes large equipment or extensive hoses. *This information was directly from my A/C certification class I took earlier this year.
This was such a great and easy to follow, important video..... Thank you so much for your excellent instruction! Looking forward to seeing more of your informational videos!
2--6 hrs minimum evacuation for a previously running system but low on gas. 12 hr overnight minimum on a system that had no gas if the system has been outta gas for a long time nitrogen sweep will be required A vac pump needs to be 2 stage Vac pump needs to be minimum 4cfm ---8 cfm for a car upto 10cfm--12cfm for a RV
After pulling a vacuum like shown in this video, will it be okay to use the can refrigerant like (AC Pro/Artic Freeze) that comes with a gauge on top to refill/add refrigerant? Thanks. 🙏
It surprises me that the simple way the valves work, doesn't allow air to be drawn in when you've created a vacuum, and remove the coupler. I guess the springs are strong enough to prevent this? Thx.
This exactly the problem I am having. The spring in the valve is not strong enough to overcome the vacuum - and allows air to enter into the system (which is under vacuum). I have not seen any videos address this.
What is the logical reason to let the pump run over night? How much volume of air can be in that AC system? Not very much. Once the air is sucked out, the vacuum is created, so why let the pump run all night?

Really like how simple to speak very good with the way you speak and good clear to understand

👍😃
Your tip about not tightening the coupler valve snug is so important! These valve cores can be bent easily.
Great video brother GOD bless you
Very informative video. Really appreciate it. Looking forward to next video, how to put refrigerant back into the system. Thanks again.
That was the best you tube explanation and applied procedure to vacuum and A/C system. Thank you.
Ty, Goodluck on that world record
Very simple and straightforward
👍✝️ thanks Paul.
I dont have a car anymore ..... But I trust YOU cuz Sparky looks like an Honest mechanic!!
👍😂

You the BEST OF BEST👍👍👍👍I WATCHED A LOT VIDEO 😱😱😱😱YOUR VIDEO PERFECT and EASY and TO THE POINT👍👍👍👍👍👍👍
Great video..................to the point. Thank you
I only clicked on your link because you look like Red Foreman! lol
very detailed thank you brother
Very good video
Have u had a instance where vac gauge would not arrow down to 29...vac has been pulling near 12 hrs
I think it depends on elevation. Down at sea level it's -29.9psi vacuum. In the mountains 4700 ft it only can vacuum down to -24 -25 PSI.
Sparky needs a hair cut around his eyes so he can see through his hair 🤣
ya remove the hoses befowa ya put d gas in ????

Does it matter which end of the yellow hose goes to the vacuum?? One end has a one way valve and the other end is open so it would seem to matter
You only pulled the vacuum to 20 i though it had to be 30
Why can’t you just use the can and gauge kit without the can and just release the pressure that way ?
You need to pull vacuum to get moisture out of the system
