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_bran... and check prices here http://repairpal.com/estimator?car_type_id=2764
