A common misconception is that A/C units generate cold. However, Air conditioning works as a heat exchange system, so it removes heat from indoors and pushes it outside. By running a window A/C unit inside you are just moving the heat from one side of the a/c unit to the other, and since it is not a 100% efficient machine, you will in fact be generating heat and create an overall rise in temperature.
You can move your window air conditioner anywhere you want to put it as long as it sits in the window.
There is no such product as an air conditioner window. However, you can buy a used window air conditioner on eBay or Craigslist. You can also check the classifieds in the local newspaper.
Most of the ones that I have seen have dirty condensor coils. That's the coil you see from the outside. They get dirty on the inside of the air conditioner where the fan blows air through it.
