AC Service | Carrier’s solution was a closed system condensation and evaporation unit that used ammonia as a refrigerant. This crude early system used much the same principles as modern air conditioning units and completely solved the printing problem by maintaining a constant temperature and humidity level in the work area. This new ability led to a flourishing in several other industries that benefited before, during, and after the production process. Film, tobacco, processed meats, medicine, and textiles were just a few of these improved industries.

In 1915, Willis Carrier founded the Carrier Engineering Company with an initial investment of $35,000. The company has surpassed five billion dollars of sales. Still, the purpose of the company when it began was to provide air conditioning for industrial purposes. In 1924, the first “comfort” air conditioning system was installed in the J.L Hudson Department Store in Detroit, Michigan. The response of the customers to the cool interior of the store was dramatic. Movie theaters, like the famed Rivoli Theater in New York City, were the next to realize the advantages of air conditioning. Customers would flock to the cool theaters to beat the summer heat.

Four years later, in 1928, Willis Carrier introduced The Weatherman. This was the first air conditioner designed for residential use. Sales started off slow due mainly to the depression and then World War II. In the post war years, the air conditioning boom began, and has continued unabated until the present day. Willis Carrier did not invent the first artificial means of cooling air, but his basic air conditioner invention is the one that is still used world wide today, and he certainly deserves the title of the inventor of the air conditioner.
