Your tip about not tightening the coupler valve snug is so important! These valve cores can be bent easily.

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. 🙏

👍✝️ thanks Paul.

[@surgingcircuits6955]

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.

Very informative video. Really appreciate it. Looking forward to next video, how to put refrigerant back into the system. Thanks again.

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

[@TimothyKoffel]

Have u had a instance where vac gauge would not arrow down to 29...vac has been pulling near 12 hrs

[@axemanjoe2945]

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.
