History of Air Conditioning in Houston

air conditioned neon signHouston was once touted as the “World’s Most Air Conditioned City”. Quite a claim for a city that by 1920 cooled its rooms, auditoriums and restaurants by placing a block of ice in a container and then circulating the ice water to fan radiators.

The first public room in Houston to be air-conditioned was the Rice Hotel cafeteria which was air-conditioned in 1922. The Second National Bank was the first air-conditioned building in Houston. An air-conditioner unit was installed there in 1923. Two years later, the Majestic Theatre followed suit. And by 1927, the other movie palaces on Main Street were air-conditioned as the public began expecting cool comfort to enhance their movie viewing pleasure. Houston’s first private home wasn’t air-conditioned until 1932.

The May 1938 issue of “Houston”, the old Chamber of Commerce magazine, described air conditioning as “manufactured weather”. According to that issue, there were 427 air conditioning units already installed, including 126 private homes. Houston at that time had a population of almost 400,000.

Air conditioning was still a luxury for most people through the  World War II era. It wasn’t until the 1950s that air conditioning became a middle-class necessity. All new office buildings were constructed with air conditioning. Local city journalists kept a close eye on the expansion of air-conditioning, using Census results to explain how Houston was indeed “the air-conditioning capital of the world.”

In 1965, Houston opened the “Eighth Wonder of the World”. The Astrodome was not only the world’s first dome stadium, but it was also the first air-conditioned stadium.

The overall acceptance and need for air conditioning was the beginning of the end for the typical home design with big front porches, wide eaves and high ceilings. The new, sought-after ranch homes with their low ceilings were much easier to air-condition than the old styles with their high ceilings. Air conditioning also claimed responsibility for the tremendous growth of Houston and other Sunbelt cities. Well, of course! Living through a Houston summer is only endurable if you have access to air conditioning!

The First Definition of Air Conditioning

Wilson authored a book titled “Air Conditioning, Being a short treatise on the Humidification, Ventilation, Cooling, and the hygiene of Textile Factories – especially with relation to those in the U.S.A.”. Wilson created what is thought to be the first functional definition of air conditioning. This same definition is what Willis Carrier, the “father of air conditioning” adhered to in his manufacturing of air conditioners.

  • Maintain suitable humidity in all parts of a building.
  • Free the air from excessive humidity during certain seasons.
  • Supply a constant and adequate supply of ventilation.
  • Efficiently remove from the air micro-organisms, dust, soot, and other foreign bodies.
  • Efficiently cool room air during certain seasons.
  • Heat or help heat the rooms in winter.
  • An apparatus that is not cost-prohibitive in purchase or maintenance.

For the most part, these statements still accurately define what modern air conditioning systems accomplish today, more than 100 years later.

The Invention of the Modern Air Conditioner

Willis Haviland CarrierIn 1902, Willis Haviland Carrier developed the first modern air conditioning system.

He was a young electrical engineer trying to solve a humidity problem at the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, N.Y. In the warm summers, paper stock at the plant would sometimes absorb moisture which made it difficult to apply the layered inking techniques.

Carrier caused the air inside the building to blow across chilled pipes. The cooled air didn’t carry as much moisture as the warm air. The process reduced the humidity in the plant, which stabilized the moisture content of the paper. This experiment to reduce the humidity had the side benefit of lowering the air temperature, but turned out to be an important step in creating modern air conditioning system.

Carrier had become the father of cool!

What is a TON of cooling?

Today, a ton of cooling is defined as delivering 12,000 BTU/hour of cooling. BTU is short for British Thermal Unit. The BTU is a unit of heating – or in this case, cooling – energy. A window air conditioner is usually less than one ton. A small home central air conditioner would be about two tons and a large one about five tons.

Winter Weather Trivia

winter dog w hatThe winter of 2013 / 2014 has NOT been a record winter. When the final monthly statistics come out, January in the U.S. won’t be near record cold.

This crazy weather is not just a U.S. thing. Parts of South America and Australia have had much warmer than normal weather this winter. Parts of Europe have been cold and stormy, others record warm. For much of January, Greenland was 8 degrees warmer than norm. Hey, let’s go to Greenland!!

The Winter of 1779-1780 was so cold that ice was piled 20 feet high along the Delmarva Coast and stayed there until spring. The upper portion of the Chesapeake Bay and the entire Potomac River was frozen solid. People were able to walk from Annapolis to Kent Island and from Alexandria into DC.

Lowest world temperature: -128.6°F / -89.6°C, Vostok Station, Antarctica, 21 July 1983–without windchill.

Lowest world temperature in inhabited area: -90.4° F / -68° C, Oymyakon, Siberia (pop. 4,000), 6 February, 1933 and also at Verkhoyansk, Siberia, 3 January, 1885.

Lowest USA temperature: -79.8° F / -62.1° C, Prospect Creek, Alaska, 23 January, 1971.

Lowest USA (48 contiguous states) temperature: -69.7° F / -56.5° C, Rogers Pass, Montana, 20 January, 1954.
