That's not the only thing required to properly install an ac unit. Do you genuinely believe people die rather that drill a hole? Lile that's the blocker? What a weird take
I’ve installed them myself, there’s not a whole lot more to it. Even easier if you have double hung windows to mount one on, though my understanding is that they’re not that common in Europe.
Not a whole lot more? Mounting a 40kg external unit on the facade of a building on the 5th floor is nothing to you? And that's after you get a permit to install it on the facade, which you will likely not (depending on the country).
If you have a balcony, you can mount the external unit there, but then you need to route the piping to the room(s) that need AC. Then you need to cover the pipes somehow, which is still perfectly doable, but goes way way beyond "drilling a hole".
You can have a portable unit, but it's loud, takes up space indoors and needs to be stored somewhere most of the year when it's actually cold rather than super hot.
Certainly not getting it done with that attitude. I’m in China at the moment, none of this stops the Chinese, their highrises are festooned with the things.
It’s ~25kg for a 2.5kw/9000 btu condenser I just looked at, but yeah, if there’s no balcony/fire escape, and you’re well off the ground, you might need some rappelling gear, and you might want a pro. No idea about whatever heavy bureaucracy you live under, that’s a human imposed rather than fundamental challenge. Pipe routing isn’t a big deal, the copper lines are very flexible, just need to be careful not to kink them - give the bends a good radius. And to answer your unstated objections, you will need some tools you almost certainly don’t have lying around. Mostly, though, you need an attitude of being able to do stuff, and getting it done.
Or you can get a portable or window unit. Midea makes some really nice window units now. Might need hung windows, though, not sure whether it’s possible to make them work with casement windows. It takes a little space, but that doesn’t seem like a huge deal?
