The window air conditioner was an amazing invention when it first appeared in the 1950s. For the first time, homes had affordable options for mechanical cooling. Central air conditioners were too expensive and most houses didn’t have the space for the ductwork necessary.
Central cooling systems have come a long way in sixty years. They’re less expensive and modern homes are designed with them in mind. But if you live in an older house or one that wasn’t built with ductwork, you’re probably still depending on window air conditioners for keeping your summer cool.
