Fun Fact Friday!😁

Did you know that Benjamin Franklin contributed to the principles behind air conditioning? His experiments with evaporative cooling laid the groundwork for understanding these principles. 🧪

Franklin collaborated with chemistry professor John Hadley at Cambridge University. 🕍They tested various volatile liquids on the bulb of a mercury thermometer. 🌡These experiments demonstrated the core principle: evaporation cools surfaces.❄️ In modern air‑conditioners, this is achieved in the evaporator coil, where a coolant liquid evaporates, absorbing heat from indoor air.

Hope everyone has a nice, cool long weekend!😎

Did you know that by the 1930's TRANE was producing air-conditioning equipment for railroad cars? 🚂So, before TRANE was keeping your home cool, they were helping keep passengers cool on the rails!🚞❄️

TRANE has been keeping people comfortable on the rails, and at home for nearly a century. 🚂🏠

Did you know that one of the first completely air-conditioned educational buildings in the country was right here in the Chicago suburbs at Glenbrook South High School in Glenview, Illinois? 🏫

Glenbrook South High School opened in 1962 and the AC was part of the design vision of Dr. Norman Watson and his administrative team. ❄️The intention of this was to enable the school to be used year-round. ☀️

While the building has changed a lot over the years, one thing remains the same: each Fall brings a new group of students ready for a new year of learning and growing. 👩‍🏫🙋‍♀️🙋

Here's to a great school year! Good luck to all the teachers, students and families heading back to school this week! 🚍📕📚

Did you know that in 1925, The Aerologist became the first air-conditioning trade journal? 🖋️ It was published by Dr. Earl Vernon Hill, an air-conditioning expert and consultant with the Holland Institute of Air-Conditioning.

And here’s another cool fact: The Aerologist was published right here in Chicago! 🌬️

The publication helped promote the idea that controlled indoor air could improve comfort, health, productivity, and modern life.

Chicago has been part of HVAC history for more than 100 years—and the industry has come a long way since then. ❄️

Have a great weekend everyone!🌞
