A Split Ac would be ideal for the bedroom. Since the compressor is outside, it won’t make much noise or vibrate. The unit inside looks quite good and compliments the room as it is placed high on the wall.
A 1.5-ton unit would be suitable for a 160 square feet space. The high placement of the split AC ensures that ample space is cooled, and you get comfortable quickly. Inverter AC would also be good.
