Running in fan model, the cost will be much less than on the cooling mode. The reason is:
In cooling mode, the compressor on the outdoor is working in order to circulate the refrigerant in the AC system. Both outdoor and indoor units are working.
In fan mode, the compressor on the outdoor unit doesn't work, only the indoor fan works, that's the why it will be less costly.
Tips: if with high humidity and medium temperature, you can try dehumidifying mode, it saves your bill also. However, if the temperature is higher than 26℃, you have to switch to cooling mode.
