@@ralphdoid Yes I just suck at making videos and I left out a few parts but after you assemble the lines you pull a vacuum and then you induce the refrigerant. This helps eliminate contaminations like humidity and air. It can also help you test for leaks during that vacuum. I have seen many mechanics do jobs and not pull it vacuum and everything is fine but I believe down the line the contaminants catch up with you.
@@ralphdoid yeah basically right after you put everything back together you pull a vacuum to verify there are no leaks and to decontaminate the system. At that point you charge the freon and turn on the car.
Do you have to create a vacuum in the system first before introducing the refrigerant?

@@carboydino Thanks for the reply. Yes, I was certain a vacuum is pulled during the process but wasn't sure at what step.
