Best cooling you can get is from Window AC.. The end
Split units no matter how good will not cool as well..
Tend to disagree with some logic. There are few reasons why the modern split types don't feel to cool as much as window AC.
1) Mostly the old window types were installed at shoulder height. That was the correct way to install AC because in a room, the cool air will settle down towards floor while hot air will go towards the ceiling. So AC had to work half and felt like it was cooling quick. I have yet to see a split indoor unit installed at shoulder height.
2) The return path of gas to the compressor is longer (at least 10 feet) in split type AC while in window type, it was merely 1-2 feet max.
3) While extending the pipes of split AC, nobody bothers to fill in extra gas.
4) IMO the older window types were less efficient due to the fact that evaporator (the cold part) and condenser (the hot part) were only about 2 feet away and soon the shielding / sealing between hot and cold parts becomes ineffective due to weather effects.
5) Looking at the size of 1.5T windows AC compressor and 1.5T Split AC compressor, it feels like the Window type had bigger compressors (though those big ones were piston type and now we have rotary type compressors with lesser life at the cost of reduced power consumption). May be these days the split units manufacturers started cheating about AC size (giving 1T stating it 1.5T)
