This listing is for a *single*, *non-inverter* air conditioning unit component. It's crucial to understand that it's *not* a complete air conditioning system. It's either the indoor blower (evaporator unit) *or* the outdoor compressor (condenser unit), and *not* both. This unit utilizes R22 refrigerant. The product is explicitly stated as 'Bukan Satu Set' which translates to 'Not a Set' in Malay, emphasizing it is a single component for replacement or specialized use, not a full system.
