In hotter, more humid climates the introduction of air conditioning came as even more of a godsend. Drive a car through Florida, relying only on ambient air for cooling, and you'll soon be enjoying a swimming pool of your own creation.
The concept of using evaporative cooling, employed in the old 'swamp coolers' you'll often see hanging off the side of classic American cars, dates all the way back to ancient Egypt - with air being passed through evaporating water to alter a room's climate.
This might sound like a relatively minor issue but, for S&W, it was a serious one. Because the company was trying to print multi-colour documents, in which the colours were applied one at a time, the minutely shifting dimensions of the paper wreaked havoc with the quality of each print. Production was being delayed, quality was falling, and wastage was going through the roof.
Engineer Willis Carrier, who worked for the company brought in to resolve the issue, set about fabricating a solution. After all, existing technology let engineers control air temperature and alter the humidity of the air - but precise control of these myriad factors, particularly humidity, had not been achieved.
Air conditioning systems, as the technology developed, began to make their way into public buildings - and, once the general public had experienced that cooling chill, it became a much-appreciated and desired luxury. As refrigerants developed and the hardware began to get more manageable, more sectors benefited from the system.
Naturally, given their enclosed cabins, applying the technology to cars was a logical step. In 1930, a company called C&C Kelvinator built an air conditioner that was installed in a customised Cadillac. As you may expect, it wasn't exactly subtle - with a huge compressor unit slung out back. Size and complexity meant that this remained a bespoke, expensive solution.
The system, construction of which was contracted out to Bishop and Babcock manufacturing, cost $274 when it went on sale in 1940. Today, that's equivalent to over £4000. Despite the hefty price tag, around 2000 Packards were equipped with air conditioning.
It was much the same as that you'd find in a car today, with a compressor, condenser, evaporator and drier; only one control was fitted, though, which regulated fan speed, and there was no temperature control. If you wanted to switch it off, you had to manually remove the compressor belt as no clutch system was fitted.
The complicated and primarily boot-mounted set-up was withdrawn after 1941 but the concept had been proven to work and, as technology progressed, other manufacturers picked up the baton after the war.
More practical set-ups were introduced in 1953 by GM, Chrysler and Packard and, in 1954, Nash - in conjunction with home appliance company Kelvinator - introduced a compact, front-mounted clutched system. The 'All-Weather Eye' was cheaper, smaller and weighed around 60kg, half of some other systems.
By 1964, Cadillac had introduced a climate control system called 'Comfort Control'. Like today's systems, all the driver had to do was pick the temperature and the system would strive to attain and maintain the desired climate.
In any case, as the race to improve passenger comfort gathered speed, air conditioning became far more common. As the original Packard advertising proudly stated, 'Costs extra, but you'll bless it every mile you drive!'
