Just purge that air out.

How do they eliminate complaints from being posted from unhappy DIYers?

LOL 2:29 while letting audible gasses out of the valve… he stated he was convinced there was no air left in the system.

This guy is a genius.

Vigilance. If they find a negative post, they delete it. They may also review all comments before posting them. Just because it’s posted doesn’t mean it appears to the public.

No.

A genius would have used a valve core replacement tool that doesn’t allow the refrigerant to escape or allows air to enter the system.
