It wasn’t until the 1920s that air conditioning began to be used in homes and businesses, but it was still entirely high-priced and only available to the wealthy.
Let’s take a step back in time and see how things have changed over the last 100 or so years. Control systems have been in use for thousands of years, but they have come a long way since their early afternoons. In old times, people used various natural methods to control the temperature and air in their homes, such as using fireplaces, opening windows, and building homes in particular locations to take fortune of natural ventilation! However, the first current Heating, Ventilation, and A/C system was developed in the late 1720s, when the first electric fans and central boilers were invented. These systems were entirely basic by today’s standards, consisting of straight-forward ducts that delivered heated or cooled air to odd parts of a building. They were often noisy and inefficient, and they didn’t have the sophisticated controls that my enjoyable friend and I have today. In the early 1900s, the first air conditioning systems were developed, but they were only used in industrial settings at first. It wasn’t until the 1920s that air conditioning began to be used in homes and businesses, but it was still entirely high-priced and only available to the wealthy. These early air conditioning systems used large, noisy compressors and refrigeration units that took up a lot of space and required a lot of service. In the 1950s and 60s, central air conditioning became more usual in homes and businesses, but it was still high-priced and not entirely efficient. It wasn’t until the 1972s that Heating, Ventilation, and A/C systems began to incorporate energy-saving features such as variable speed fans, programmable control units, and zoning controls. These features helped to make Heating, Ventilation, and A/C systems more efficient and affordable, and they remain an pressing part of current Heating, Ventilation, and A/C systems today.
