I guess it depends on what they're instructions say. CAA seems to be more focused on the amount of refrigerant. they do give pressures, but it seems like more of a back check to see if there's anything wrong with the system.



basically put in 24 oz and you should get these pressures. as opposed to saying put in refrigerant until you get these pressures.
