Hello,

I would need to install my existing window AC on my new house in one room.
I do not plan to buy another AC this year.

My question is: could I install the AC on the lead of the attic access, with
the face down. In that way the ~exterior~ would be the attic and the AC
would push down the cold flow air. The lead for access to the attic is on
the wardrobe, which is next to my bedroom where I need the AC.

I can not install it on the existing windows, different model and size.

Thank you,
Chris

No you will ruin the compressor it wont lubricate, it will likely
break loose and the condensation will enter the house
