How to Install a Window Air Conditioner

What type of window do you have?

• First, look to see what type of window you have. Window air conditioners fit best in single- and double-hung windows that slide vertically.

• Casement windows that crank open and horizontal sliding windows don’t work as well for window air conditioners.
• If you have a storm window, you may need to remove the screen or slide open the lower window.
