Hi folks!

I'm wondering if a mobile split unit installed through a roof window that, itself, is atop a mezzanine would work well enough to keep the whole room at a liveable temperature?

My living room is ~30sqm with a lot of height, hence the mezzanine right underneath the roof window i have. Since cold air falls and warm air rises, I would tend to think the fresh air would scatter downstairs into the main part of the room (which i spend time in), though I'm looking for advice before purchasing anything.

(can't install it on my main windows since they give on a closed courtyard.)

Thanks for the advice!
