On amazon in the US you can get either a 12,000 btu through-the-wall AC unit for about $700 or a 12,000 btu wall ductless mini-split(heat pump, so AC and heat) for about $850. For either of those you can find models for cheaper or more expensive. I just chose general middle of the road prices. So the cost is no longer 5x, the prices are becoming a lot more comparable for heat pumps vs regular ac units. Also, if you check out the efficiency ratings, for most mini-splits these days, you'll make up the cost difference in your electrical bill vs a run of the mill AC unit in the medium to long run.

Your mention of through-wall models reminded me: I've been wondering for a while why I can't get window-mounted heat pumps at a reasonable price. I recognize the limitations on insulation, but as I'm not yet at a spot in my renovation where I can do heat pumps comprehensively and seeing as how I'm looking for another air conditioner for the first floor of my house, buying one that's reversible seems like an obvious thing. (Maybe like that around-the-window Midea model? That seems kind of obvious to me, but I am not an engineer.)

This startup has a neat idea, and I hope to see more about it - https://www.gradientcomfort.com/ - but $2000 feels like it's not competitive.

And if anyone happens to know of one (and not an AC that will just do electric heat) available in the USA, I'd be grateful to hear about it. Amana will sell me one - for $1300 for 12K BTU, and that sounds...high.

If only it were possible to use something like that with tilt turn style windows.
