This replaced an old Fujitsu A/C unit. I should have replaced that years ago :), the Midea is much more efficient, quieter and cools more effectively. A split cycle unit would be quieter, but the room layout made that difficult and I'd have had to deal with Gold Coast tradies :{. This was a clean drop-in for the hole I already had in the wall. Noise level the only minor niggle but I knew that and it is tolerable.
