The world we live in would not be the same if air conditioning weren’t available. Entire regions of the world would have remained undeveloped, sustaining minimal populations, if air conditioning hadn’t become a part of our lives.

Today air conditioning is rightly considered a necessity rather than a luxury. A good amount of economic activity, and hence progress, would not have been achieved without it. It is one of the key inventions sustaining modern life. In fact, the Encyclopaedia Britannica lists air conditioning as one of the greatest inventions of all time.
