Hold on to your butts, comrades. We're about to get a preview of 2050. I just checked the live data, and the area off the coast of South America that is the index water for ENSO is 9° F above average in places. This is going to be a wild year.

prices do typically drop in colder months, at least in my area (midwest usa). I would suggest being open to traditional window units as well as they’re typically cheaper than the kind you’re describing (and equally effective iirc). You do need to drill a couple holes into the window frame but the holes won’t even be visible when the windows closed.
Idk what landlord/rental rules are like where you live but personally I’d tell a landlord to go fuck themselves if two holes at the bottom of a window was a major issue.
I am aware these exist thanks to reading US comments on the web, but I have never ever seen one in the EU. Then again I very very rarely see windows that open like these here either.
If you can't drill / install an actual unit (with external condenser) we either have those, which are extremely inefficient energy-wise, don't work that well, and require you to have a large tube connected to the outside (so window opened with an isolation kit), or stuff like these where it's an actual AC unit with an external block - the condenser - but transportable, and you still need a cable to the outside but a much smaller one (along with an isolation kit).
Yes, I was looking at one similar to the last example. They exploded in price.
If you get the former, with the single hose, they have a really stupid design choice where they drop the second hose it needs to work properly, which makes them massively less effective. However you can easily duct tape a second hose over the heater-intake to make it work properly.

Ahh, having just one hose for marketability is so stupid! Thanks, the pictures helped me understand at a glance how, with just one hose, air pressure inevitably must lead to warm air rushing in from somewhere if the machine is supposed to work at all, even if you close the doors and windows. It's clever to fix this terrible design flaw.
