Window Unit A/CProbably everyone has had this thought at least once a summer, while sweating through their clothes on a subway platform or in a parking lot, desperate to locate their car: how did people survive before air conditioning? Although we may not be able to imagine summer without it, prior to its invention by Willis Carrier in 1902, people did still managed to live and go about their business in New York, and even in cities like Savannah and New Orleans. Here’s how they did it.
They built their houses differently
We may not think about it much, but the invention of the air conditioner radically changed the way people built buildings, especially in the south. You may have noticed that older buildings tend to have much higher ceilings: this allowed heat to rise so inhabits could enjoy the cooler space below. Deep eaves and porches protected windows from the heat of the sun, and it was common to plant trees on the east and west sides of a house for additional shade.In addition to this, rooms were designed with windows on opposite sides of the space, which allowed for cross ventilation. Air likes to have a place to go, so opening up a single window won’t generate much air movement. But open two windows right across from each other and you can get a nice breeze going. In cases where it wasn’t possible to have two windows on opposite sides of a single room, architects would line up rooms in a row, allowing air to flow between them. You can see this in old shotgun homes in New Orleans or in railroad apartments in New York.
They got outside
Currently the porch, like the fireplace, is a charming but somewhat vestigial architectural feature. But in the past porches were incredibly important, not just for shading the windows of a home, but also for providing a place where people could sit outside, out of the glare of the sun, and perhaps enjoy a breeze. These days, when it’s hot, people flock inside, but in the past it was the opposite: temperatures indoors and out were more or less the same, and the porch was much less stuffy than the rest of the house. This led to a whole culture of people sitting outside on their porches after supper, which has essentially disappeared. Some older houses were also built with sleeping porches, screened-in porches where one could sleep during the summer, enjoying the breezes but protected from bugs. New Yorkers replicated this by sleeping on the fire escape on especially hot days.
They took naps
One way to cope with the heat of the sun is by changing your schedule. People in parts of southern Spain still do this – they nap during the hottest hours of the day,resume work later in the afternoon, and then shop and socialize once the sun has gone down. People in the American south used to do this too – witness the scene inGone with the Wind where all the ladies take naps.
They … went to the movies
Even after the invention of the air conditioner in 1902 (and the window unit A/C in1939), air conditioners were prohibitively expensive and still out of the reach of most people. The one place in most towns that was air-conditioned was the movie theater. People would flock there to enjoy the artificially cooled air, which helped contribute to the rise of the summer blockbuster.
They got creative
There are all kinds of crazy solutions to stay cool, from cuddling frozen waterbottles to braiding ice into your hair. People in the past were equally resourceful —anything from hanging wet laundry in doorways (creating a sort of swamp coolereffect) to (allegedly) placing one’s underwear in the icebox.
