What You Might Not Know About HVAC


During the summer, it’s essential that you have an air conditioning system in your home. There’s nothing more relaxing than stepping into a cool house after being outside in the hot sun all day. So who was the person that created this magnificent system? How have air conditioners changed throughout the years? Here are some facts you might not know about HVAC systems.

The First HVAC System Began In 1902

It’s hard to believe that air conditioning wasn’t around before the 19th century. How did people survive those blistering hot summer days? It wasn’t until one innovative man, Willis Carrier, stared through the mist and realized that he could dry air by passing it 
through water to create fog. Doing so would make it possible to manufacture air with specific amounts of moisture in it. Within a year, he completed his invention to control humidity which is the fundamental building block for modern air conditioning.

Ancient Cooling Systems

Even before the 20th century, humans were using even more basic forms of cooling their homes. The Ancient Egyptians used water to cool their homes. By dipping mats into 
water and hanging them over their doorways, they lowered the temperature in their homes. How did it work? Due to the extreme heat, water would evaporate from the wet mats and add moisture to the dry air. Thus, slightly cooling the inside of their homes.


The 19th Century Movement

In 1820, British inventor Michael Faraday experimented with the refrigeration properties of gases. During this time, he figured out that compressing and liquidizing ammonia, allows the gases to evaporate, and he could cool the air in his laboratory.  


A few years after Faraday made his discovery, John Gorrie developed a machine that allowed him to keep yellow fever patients cool. The invention that Gorrie created was unique since it compressed air and water to create an open cooling system. This type of invention was the first of its kind. In 1851, Gorrie’s “cold air machine” was the first patented invention that facilitated mechanical refrigeration.

Modern Day HVAC


Did you know that only 10% of American homes had air conditioning units in 1965? Even though a majority of the South, Midwest, and West primarily use central air systems, the type of air conditioning equipment is different across the various regions. In the Northeast, single-room air conditioning is the norm, 
whereas

in the South, major, whole-house air conditioning units are typically installed.
