This week—August 15, to be exact—celebrates the climax of Air Conditioning Appreciation Days, a month-long tribute to the wonderful technology that has made summer heat a little more bearable for millions of people. Census figures tell us that nine out of ten Americans have central air conditioning, or a window unit, or more than one, in our homes; in our cars, it’s nearly universal. Go to any hardware or home goods store and you’ll see a pile of boxes containing no-fuss machines in a whole range of sizes, amazingly affordable, plop-’em-in-the-window-and-plug-’em-in-and-you’re-done. Not only do we appreciate the air conditioner, but we appreciate how easy it is to become air conditioned.
One of the first cooling contraptions offered to the public showed up around 1865, the brainchild of inventor Azel S. Lyman: Lyman’s Air Purifier. This consisted of a tall, bulky cabinet that formed the headboard of a bed, divided into various levels that held ice to cool the air, unslaked lime to absorb humidity, and charcoal to absorb “minute particles of decomposing animal and vegetable matter” as well as “disgusting gases.” Relying on the principle that hot air rises and cool air sinks, air would (theoretically) enter the cabinet under its own power, rise to encounter the ice, be dried by the lime, purified by the charcoal, and finally ejected—directly onto the pillow of the sleeper—“as pure and exhilarating as was ever breathed upon the heights of Oregon.” Lyman announced this marvel in Scientific American, and in the same issue ran an advertisement looking for salesmen. Somehow the Air Purifier didn’t take off.
More interesting to homeowners was the device that showed up in 1882, the electric fan. Until then, fans were powered by water or steam, usually intended for public buildings rather than homes, and most of them tended to circulate air lazily. But the electric model was quite different, with blades that revolved at 2,000 rpm—“as rapidly as a buzz saw,” observed one wag, and for years they were nicknamed “buzz” fans. They were some of the very first electrically powered appliances available for sale. They were also exorbitant, costing $20 (in modern terms, about $475). But that didn’t stop the era’s big spenders from seizing upon them eagerly. Delighted reviewers of the electric fan claimed that it was “warranted to lower the temperature of a room from ninety-five to sixty degrees in a few minutes” and that its effect was “like going into a cool grove.”
The fan combined with ice around the turn of the century, producing an eight-foot-tall metal object that its inventor called “The NEVO, or COLD AIR STOVE.” The principle was simple: air entered through a small pipe at the top, was pulled by a fan through the NEVO’s body—which had to be stuffed daily with 250 pounds of ice and salt to provide the cooling—and would then be discharged out an opening at the bottom. “It dries, washes, and purifies the air.” As the NEVO had more in common with a gigantic ice cream freezer than with actual temperature control, and the smallest NEVO cost $80 (nowadays, $1,700) and cost $100 per season (over $2,000) to operate, it didn’t get far.
By this time, a young engineer named Willis Carrier had developed a mechanical system that could actually cool the air and dry it, the Apparatus for Treating Air. But this was machinery of the Giant Economy Size, and used only in factories. In 1914, one wealthy gent asked Carrier to install a system in his new forty-bedroom Minneapolis home, and indeed the system was the same type that “a small factory” would use. Unfortunately, this proud homeowner died before the house was completed, and historians speculate that the machinery was never even turned on.
It wasn’t until 1929 that Frigidaire announced the first home air conditioner, the Frigidaire Room Cooler. This wasn’t in any way a lightweight portable. The Room Cooler consisted of a four-foot-tall metal cabinet, weighing 200 pounds, that had to be connected by pipes to a separate 400-pound compressor (“may be located in the basement, or any convenient location”). And it cost $800, in those days the same as a Pontiac roadster. While newspaper and magazine articles regarded the Room Cooler as a hot-weather miracle, the price (along with the setup requirements) meant that its customers came almost solely from the ranks of the rich, or businesses with cash to burn. Then fate intervened only months after the Room Cooler’s introduction when the stock market crashed, leaving very little cash for anyone to burn. Home air conditioning would have to wait until the country climbed back from the Depression.
Actually, it waited until the end of World War II, when the postwar housing boom prompted brand-new homeowners to fill their houses with the latest comforts. Along with television, air conditioning was at the top of the wish list. And at last, the timing was right; manufacturers were able to offer central cooling, as well as window units, at affordable prices. The compressor in the backyard, or the metal posterior droning out the window, became bona fide status symbols. By 1953, sales topped a million units—and the country never looked back.
Appreciation? Of course. And perhaps, adoration.
