Crank out windows can be a bummer when the summer heat hits. Also referred to as "slider" windows and "casement" windows, the common window air conditioner won't work here. Typical window air conditioners are wider than they are tall, and they won't fit into a casement window. And unfortunately you can't just tip a normal AC unit on its side for use in a narrower window.
Dealing with crank out windows can definitely be a hassle. Even if a typical window air conditioner will fit into a slider window gap, you'll need to DIY a support system to keep it in place - and there are plenty of DIY projects online of people doing this!
There are a limited number of casement air conditioners available, so you'll have to compare the cost (both the upfront cost as well as the time and energy of installing it) against using a portable air conditioner instead! (For more information on ACs, check out our air conditioner buying guide.)
