Consider Installation

Don’t overlook the importance of where you want to install your air conditioner. Not all windows are the same.  Whether you have double-hung windows that slide up and down, casement windows that crank out, or horizontal sliding windows, there are models designed specifically for each type. Unless you’re replacing your air conditioner with the same brand and dimensions, you’ll need to install a new cabinet, sometimes called the sleeve.  Sleeves installed in windows must always be supported by brackets secured to the outside wall.  Some models do not include window mount kits so you’ll have to purchase seperately.

An alternative to window installation is thru-the-wall installation. If your unit is a heating and cooling model used throughout the year, or you simply prefer to not lose your window view, then you may want to consider a permanent installation in an exterior wall.

Most window-style room air conditioners can also be installed in a permanent thru-the-wall installation. In these situations, outside mounting brackets can be used for additonal support, or more often than not, omitted.  Some manufacturers, like Friedrich, make models specifically designed for thru-the-wall installations. (Our WallMaster series.) In any case, when you install thru-the-wall, make sure that your unit has a slide-out chassis, or you’ll be in for a lot of work whenever you remove your air conditioner for maintenance or service.
