No, not specifically "Freon". As with most Air Conditioners it uses a phase change cooling system. For this size unit typically R-134a is used as the refrigerant. In the USA discharging and recharging these cooling systems requires a license. Usually the act of changing refrigerant is only done when the system has a malfunction.
