They make a special type of window ac for those windows. You should buy the proper unit.
it exhaust the air
I am looking for a window AC unit to use in my whole house. What is the BTU's one would need to cool a whole house?
yes
It will not work, the ac unit needs to blow the heat removed from indoors to outdoors. Running a window ac unit without venting it outside will make the room hotter.
My hubby says AC
Have you checked it's switched on?
This depends on the ac unit. Some are definitely made for horizontal only and some allow vertical installation. Check the installation manual; if you don't have it then most of them are available online.
I need this answer as well. Anyone?
Many home AC units are sealed, and there is no way for a homeowner to add refrigerant.
