Could you elaborate a little on this?

I have a free-standing air-conditioner that I got because temperatures hit records this year, are you saying I should put the cold side of it outside and pipe the tube into my home?

Split A/C units (like ceiling mounted ones) are uncommon in most of Northern Europe residential buildings..

Unfortunately those free standing units create a pressure differential and you will see all your hot air pushed outside. The split units use a fluid line to the outside to exchange temperature, so you would need one of those.

They are awesome and in Germany you can get up to 45% installation cost help
