"Switzerland outright not allowing residential ACs": That's not completely true, though. First, mobile/portable ACs are allowed pretty much everywhere in Switzerland, I think. Then, for fixed ACs, it depends in which canton you live. Geneva is the strictest, but in most cantons, fixed ACs are allowed under some conditions. Where I live, 50% of the AC energy must come from renewables (which is pretty easy if you have solar panels). Anyway, with all those recent heat waves, I'm pretty sure those rules will soon be relaxed in all cantons.

In Geneva even some mobile ACs, such as mobile split units, are banned without a permit https://www.ge.ch/rafraichir-climatiser-batiment/installatio.... The only ones which are allowed are monoblock mobile ACs. Which is ridiculous given that they are the least efficient and consume way more energy than split mobile units or fixed ACs.

Great when mobile ACs are mostly terrible, if-nothing-else choice. They can only cool a small room temporarily.

Yes, they're terrible. That's why relaxing the rules for fixed AC is the way to go.
