Since the dawn of man, humans have sought ways to stay cool. It’s fair to say, the world was a much more humid and hot place before air conditioning was invented. The best most folks did was to sweat and fan themselves in the sweltering heat. Hand fans date back some 3000 years and were used in China.
Only the rich had luxuries of the primitive air conditioning systems, and they were so inefficient and costly that almost no one benefited from them. In what might be the first American air conditioning, an ailing President Garfield received air blown through ice water-drenched sheets to cool him. He reportedly went through 250,000 pounds of ice a month for two months.
Electricity and the Air Conditioner
When electricity became common in America in the early 1900s, most homes were at least blessed with electric fans. In 1902, an industrious engineer named Willis Carrier invented what we know as the first modern-day air conditioning system in Buffalo, NY. The machine was to cool by blowing air through coils that were cooled by water. It was intended to control the humidity of the print shop where he worked.
He was just 25 years old when he made that invention, but in 1922 he added a central compressor to it and invented the centrifugal chiller.
This meant that there was a central compressor and the unit could be smaller. When he introduced it to the public on a warm weekend in Times Square at the movie theatre, it was an instant hit. People forever decided to visit cool movie theatres on hot summer days, making for summer blockbusters.
As time went by air conditioning swept through department stores, offices, cars and the like. It was slow to catch on in residential areas even though the first private home to be designed with air conditioning service was built in Minneapolis in 1914, designed by David St. Pierre DuBose, and owned by Charles Gates. That might be because the first portable window air conditioner, one that most people might afford, wasn’t invented until 1945 by Robert Sherman of Lynn, Massachusetts.
Air Conditioning Today
Today air conditioning is fairly common in the US. Eighty-eight per cent of new single-family homes constructed in 2011 including air conditioning. That is ranging from 99% in the south to 62% in the west according to the US Census characteristics of new housing.
Your Air Conditioning Service
Air conditioning service of a tune-up, inspection, and cleaning should be done once a year on your central air conditioning unit to maintain its working order. The inspection should include checking the connections, the motor, coils, drain line, blower, operating pressures and temperature, refrigerant levels and the return and supply lines.
Making sure air conditioning service is done in the Spring means that it will be in peak performance and energy efficiency when you will be putting it in maximum use during the hottest months.
As your system runs, it accumulates dust and debris. That affects its ability to run efficiently. Running your unit efficiently saves on your utility bills plus it helps keep your unit in shape longer. Maintenance on your unit is cost-effective and way cheaper than replacing your air conditioning unit.
