Air Conditioner Installation Types: Double-Hung Windows

This is the most common window installation. On this installation, you'll see the Air Conditioner is installed in a double hung window. These are the windows that slide up and down. The air conditioner basically sits on the window sill. The upper window slides down to support the air conditioner from behind. You also have side curtains. These are designed to pull out to fill the space and to keep the outside elements from entering your home. These side curtains are held in place with the provided screws.
