Air conditioning is the innovation that led to warmer parts of the nation becoming as populated as they are today. Before air conditioning, few people wanted to live where temperatures can regularly reach well beyond 100 degrees Fahrenheit. But who invented air conditioning?

Willis Carrier

Willis Carrier is the inventor of air conditioning. He was born in 1876 in Angola, New York. He graduated in 1900 from Cornell University with an engineering degree. In 1902, the Sackett-Wilhelms Lithography & Publishing Company of Buffalo had an air quality problem that needed to be fixed. In response, Willis Carrier designed the world’s first air conditioning system.

Carrier’s Air Conditioning System

Willis Carrier designed his air conditioning system with four basic functions. These were to control the temperature, control humidity, circulate and ventilate air and improve indoor air quality. It took him until 1906 to refine and test his invention.

In 1911, Willis Carrier shared his paper on air conditioning. The paper was called Rational Psychometric Formulae. He introduced his paper at the American Society of Mechanical Engineer’s annual meeting. The paper explained dew-point temperature, absolute humidity and relative humidity.

Carrier Engineering Corporation

In 1915, Willis Carrier pooled his money with seven other engineers to co-found Carrier Engineering Corporation. The other engineers were Edward Murphy, Ernest Lyle, Irvine Lyle, Alfred Stacey, Logan Lewis, Frank Sanna and Edmund Heckel. The company was based in Newark, New Jersey.

Carrier Global Corporation

Willis Carrier died in 1950, but his company continued on. Carrier Global Corporation is based in Palm Beach Gardens, Florida. It sells heating, air conditioning and ventilating systems around the world. Its products are used in homes, manufacturing facilities and commercial buildings. It has a market cap of about $36 billion and is publicly traded on the NYSE.

Excellent service from start to finish. Joe came out to give us an estimate on what we would need for a new furnace, never pressured us to buy the top of their line just giving us options on what we would need for our home. Then the date set for installation Thomas and Ryan came out on time and did a great job.

All three technicians worked well together. They treated each other kindly and were thoughtful and courteous with me. They did a final and complete cleanup after the installment of my new heater. They were respectful of my home. I’m grateful I used this company.

Evans Mechanical is an excellent service committed to customer satisfaction and guaranteed quality workmanship. Our water heater burst and they were very responsive. They sent a technician out the same day and it was determined the heater was beyond repair.
