Window air conditioners are relatively inexpensive cooling options for rooms without central AC; however, some spaces that need cooling don't have a convenient window. Or you may not want to block your view out of the window. One option is to purchase a through-the-wall AC, which is designed for in-wall installation, but these can be a bit more expensive than a window AC. Another good option is to buy a window AC that can also be installed through the wall. Browse our selection of window units that can be installed through the wall.
