AC charging on 2000 Jeep Grand Cherokee

Do I have to decompress the AC system before charging it when its completely empty?

It needs to have a vacuum pulled on it to remove any oxygen in the system, then the proper amount of freon can be added and you can find a shop that recharges AC systems here http://repairpal.com/directory?address=06615&car_brand_names=Jeep and check prices here http://repairpal.com/estimator?car_type_id=2764
