- Window units exist, they were pretty much the standard until 30 years ago.
- You can knock a hole in the wall for a window unit too (but why?)
- Window units are LOUD as the compressor is inside with you (not as loud as portable units though)
Window units you can legally put in yourself.
Split systems in most places (and i'd 300% expect this in bong) need a licensed technician to install as the gases are CFCs.
Split systems are the best, keeps the compressor (ie. the noise) outside.
If you're only renting, you can get portable units, they're the worst but work better than nothing. The compressor is fully inside with you and you have a vent kit to a window so hot air can be vented back out (but they're rarely insulted well, so they leak the heat back into your room anyway)
Not at all applicable to blighty, but you can also get evaporative air conditioners that use loads less power (only moving parts are a big fan), but they only work in dry climates.
