Sorry I feel like some of you are under the impressions I'm trying to do this with no cooling or heating. So please let me rephrase and shorten my question.
Do they make a non window mounted unit that can cool an insulated room around 15x15 feet? Will one unit do heating and cooling or do they need to be seperate units.
About how much electricty $ do they take to run a month if they aren't on 24/7
