Are portable air conditioners as good as the one you put right into the window?
Depends on how you will use it. Remember that air conditioners expell hot air. Just stand next to an outside condenser and feel the hot air it has pulled from the house. Portables also remove humidity and usually have to be dumped when the accumulated water get too full in its bin. However, they do have their uses, as you want. They can be moved from room to room, but you better close off each room you are cooling or the air movement will simply overwhelm the unit’s cooling ability. I prefer window to portable, but realize that in some cases window mounted AC is very difficult. In those cases, a portable might be the solution, but you do have to contain the room air movement. The minute you leave a door open, you are cooling more than just the room the AC is in, thus losing the cool air it has produced for the first room.
