A Brief Timeline of Invention and Innovation: the History of Air Conditioning (One of the World’s Greatest Inventions!)
1758, United States of America
Benjamin Franklin and colleague John Hadley (professor at Cambridge University), give a presentation on an investigation of the effects of evaporative cooling. They show that evaporating inconstant liquids (such as alcohol) on the surface of water can cool an object to freezing.
1930, Washington, D.C.
President Herbert Hoover has indoor climate control installed at the White House. The next year (1931), as The Great Depression worsens, the now-infamous window air conditioning system was introduced into the marketplace.
1902, Brooklyn, NY
Willis Carter creates a machine that blows air over cold coils, which effectively de-humidifies a space, significantly lowering its temperatures. The only issue? It was enormous, measuring at seven feet high and twenty feet wide.
1970s, Anywhere USA
Air conditioning becomes widespread throughout the country, becoming more and more energy-efficient to comply with modern environmental laws and the cost of utilities.
1920, New York, NY
Willis Carter creates a smaller version of his cooling unit. This iteration allows department stores, commercial buildings, and railroad cars to add air conditioning to their spaces.
2021, Shelby, NC
CSI Mechanical, a Trane specialist, continues to innovate and perfect the trade with customized AC solutions! Our certified HVAC technicians have the training to install and service any type of Trane air conditioning system.

Out of all the companies I have used in the past 10 years since moving here, they are by far the best & most efficient.
The owner (Steven Cherka) came out and went above & beyond to fix the problem with our AC unit!
EXCELLENT customer service, & the prices are right in line – I cannot say enough good things about this company. If you’re comparing different companies in the Shelby area, and you’re unsure …. pick CSI every time!
