When you do a 12 months ac service on a working system to check the refrigerant level and function , how long do you pull vacuum ?
Is it still 20-30minutes or will it do with like 5 minutes since there shouldnt be any moisture in the system ?

If your going to pull the system into a vacuum. Might as well do it right. 15 minutes let set 10 - 15 minutes.
