You ever wonder why we call it "air conditioning?" I mean we don't call heating "temperature amplification," now do we?
It turns out that in 1906 Stuart W. Cramer, an engineer involved in the textile industry in North Carolina, developed a system using humidity and ventilation that made fabrics easier to process. Cramer was so successful he founded a town! The term "conditioning" was later adopted by Dave Lennox into his company's name.
