Summer is in full effect here in Ottawa. The temperatures are rising and the unbearable humidity is making everyone a little uncomfortable. Aside from a dip in the Ottawa river or your neighbour’s pool, people are flipping the switch on their favourite at-home comfort systems – air conditioners..

While air conditioner systems are now commonplace in the homes of many, they represent nearly a century of engineering development. From the initial concept in 2nd century China, to the energy efficient in-home machines we know today, the modern air conditioner is the product of years of progress with a very rich history; one which we believe is worth telling!

For your entertainment, Stan’s HVAC Ottawa presents a timeline of the history of air conditioning.

The Timeline to Modern Air Conditioning

2nd Century China (101 – 200 AD): Chinese mechanical engineer Ding Huan invents a rotary fan with seven wheels in diameter for air conditioning purposes that was manually powered by prisoners.

1758: Benjamin Franklin and his colleague John Hadley, a chemistry professor at Cambridge University, conduct an experiment to explore the effects of evaporative cooling. They concluded that evaporation of erratic liquids such as alcohol could be used to reduce the temperature of an object.

1851: Florida physician John Gorrie aims to create ice using compressor technology to cool air for his patients in his hospital in Florida. In 1851, Gorrie is granted a patent for his ice-making machine which ultimately improved the artificial production of ice.

1902: The first air conditioner is manufactured by Willis Carrier from the need to cool paper during the printing process. The machine created a cooling effect by blowing air over cold coils that ultimately dehumidified and cooled the air so paper would stay smooth and the ink would stay fresh. The machine was able to lower humidity levels by over 50%

1906: Stuart Cramer coins the term “air conditioning” after exploring ways to add moisture to the air in his textile mill. By combining moisture with ventilation to change the air in his factories, he was able to control the humidity in the textile plants.

1914: The first private home air conditioner is installed (made by Carrier) in a Minneapolis mansion belonging to a man named Charles Gates.

1950’s: The demand for air conditioners in suburban homes skyrocket. During the middle of the century, it is estimated that around 74,000 home air conditioners were installed.

1957: Following the invention of the rotary compressor, much quieter air conditioning units were produced that provided the same effect overall, but with much greater efficiency.

1970’s: Central air conditioning was implemented in many commercial buildings in large cities across North America.

1990: The widespread use of air conditioning units causes energy concerns prompting companies to produce more energy-efficient units to respond to modern environmental laws.

2007: The percentage of Canadian homes with air conditioning reaches 49% while US homes reach 86%

What The Future of Air Conditioning Holds

As energy efficiency standards continue to evolve, and manufacturers need to comply with environmental regulations, air conditioning systems will continue to progress towards more efficient ways of cooling.

One method in which manufacturers are achieving this is through smart thermostats. These thermostats allow you to control your home’s heating and cooling settings from an app on your smartphone. This ultimately helps to reduce your carbon footprint by lowering the amount of energy you waste.

Along with reduced waste, these smart thermostats could allow you to save money each month.
