  Any driver today simply turns a dial to cool themselves in the car, and auto air conditioning systems come standard. However, that wasn’t always the case – there used to be a day when that system was simply a luxury. In fact, modern cars aren't even advertised to come with air conditioning because it's expected: a car that is advertised to have an AC unit will sound like a car that is advertised to have tires to new drivers. Have you ever wondered how this cooling device got its start and became so popular? The History of Auto Air Conditioning The earliest forms of air conditioning began in the 1830s. A Florida hospital created a system that blew air over a bucket of ice to cool patients. In 1902, Willis Carrier created the “Apparatus for Treating Air” which is the closest mechanism to the modern day air conditioner. Also in that year, Alfred Wolff designed a system using ref ... read more

Because many areas on an automobile need maintenance, the air-conditioning system can often get overlooked. To avoid a neglected A/C giving out on you, especially in the middle of a heat wave, regular checkups are necessary. The first step to maintain your car’s A/C system is by understanding how it works. An auto air conditioning system is made up of five parts: a compressor, condenser, receiver dryer, expansion valve and evaporator. Put simply, air is cooled by a change in pressure through the system, which results in a lower temperature. When you turn on the A/C in your car, the compressor applies pressure to the system’s refrigerant (Freon), which raises its temperature. By doing so, air loses heat while it flows through the condenser; air then passes through the dryer to remove moisture and to the expansion valve where the refrigerant slows down even more, which causes the tempe ... read more
