Best Answer

First off, the refrigerant is not Freon, it is R134. If it needs refrigerant, then you have a leak. It is illegal to add refrigerant to a system without repairing the leak. You also more than likely do not have the specialized tools necessary to repair or to charge the system correctly. Take it to a professional.
