The first air conditioning systems were created by electrical engineer Willis Carrier in 1902 to solve a problem for a printing press in Brooklyn, New York, where humidity threatened to ruin the paper. Since then, air conditioning has evolved from a revolutionary thermal comfort system into an essential element of homes and workplaces. Initially, the units were large and centralized, hidden away due to their ducted system nature. However, this approach is rapidly changing as more energy-efficient efficient ductless air conditioners become more integrated into contemporary interiors.
