Professionals aside, any self respecting DIY store will readily sell you masonry drills in lengths suitable for most walls. And in the rental section, you’ll be able to get a core drill plus the appropriate machine (exactly the kind of equipment professionals will use for big holes in thick walls) for making any hole too thick and/or too deep for a regular drill. Since core drills can be extended, your drilling depth (for practical purposes) pretty much is only limited by the number of extension rods you have available.
One company I worked at rented pre-war building and installed big AC in couple of rooms. Big units at the balcony and ducts through 1m walls. 0 issues.
I just won’t. Why on earth would I run those butt-ugly air vents through my house when I can just use the existing underfloor heating to cool down the building via a heat pump in the summer?
But seriously, it’s an established solution. You don’t need to cool the floor down so much because the area is so big, so you don’t run into condensation issues.
You’d only be adding a floor heating system to a room you’d be at very least tearing the floor out of for renovation anyway. So in terms of invasiveness, it’ll only slightly prolong the work that’s being done, and create some dust from cutting slots for the piping.
In rooms that aren’t due for such a renovation, you can use existing radiators with a heat pump, too. Of course it won’t be as efficient as with floor or wall heating, but it will work. As with everything, perfect is the enemy of good enough.
Good luck running duct work or even mini-split tubing through that ancient European masonry.
I don’t see any problem, most professionals have suitable material to drill through wood, brick or concrete, to thicknesses of 1 m.
Probably difficult to understand for people who live in houses with cardboard walls.

I fully agree with your explanation.
A thick wall penetration of more than 1 m requires some experience and respect for safety.
There are machines for just that.
That … is no problem? How do you think we Europeans live?

Because the under-floor heating running in a cooling loop will create condensation on the floor? Or worse, under it?
That’s why you do it gently ;).

Adding that to a house sounds even more invasive than duct work
But they said they’d use the existing underfloor system, so there’s no need for invasive work.
