In most areas it is illegal to service an A/C system unless you have both the proper certification and an approved refrigerant recover/recycling machine. Check with you local authorities before attempting to service an A/C system. If necessary, take you vehicle to a reputable repair facility and have the system professionally discharged before beginning the repairs. If this is done, return the vehicle to the repair shop immediately after finishing the repairs to have the system evacuated and recharged.
