Air Conditioner Installation Types: Sliding Windows

Posted on May 20, 2021 By Pat D - Director of Training

Here's how to install an air conditioner in a sliding window. If your windows slide open from side to side, this is the air conditioner that fits the bill for you. In a sliding window air conditioner installation, the air conditioner sits right on the open window space on the window sill. The window to the side slides over and supports the air conditioner in place with the bar along the side. Since window air conditioners vary in height, when you install an air conditioner in a sliding window, there's a filler panel that must be cut to fill in the space in the top to keep the outside elements out of the home. This is also a great solution for those of you that have a crank out window. With those crank out windows, you would remove the entire window pane. A piece of plexiglass is then cut to fill the space, and a hole is then cut into the plexiglass for this air conditioner to be installed in.
