  • Air conditioners enable the indoor climate of a building to remain relatively constant, despite changes in external weather and internal heat loads. They also allow for the construction of deep plan houses, allowing people to live easily in hotter climates.
  • In certain parts of the United States, air conditioning resulted in a population increase. Before air conditioning made areas like Arizona, Nevada, Florida, and Texas more attractive, the nation’s booming economies were largely concentrated in the Northeast.
  • In 1902, just 20 years later, Willis Carrier went a step further and invented the first air conditioner. The 26-year-old got the idea while looking at fog on a train platform in Pittsburgh. He founded the Carrier Engineering Corporation 13 years later in 1915.
  • The world’s largest HVAC system is in the Holy Mosque in Makkah (Mecca), Saudi Arabia. To cool a space that sees up to 1 million visitors a month in a climate where temperatures frequently top 100 degrees, the system has 135,000 tons of refrigeration capacity.

Historical Facts About Air Conditioner

  • Willis Carrier invented the first air conditioner in 1902 to monitor the humidity in a New York publishing house, not for warmth.He created it to prevent his paper from expanding and contracting, as well as to ensure that his ink dried quickly and without smudges.
  • In 1929, Frigidaire launched a new split-system room cooler that was small enough for home use and shaped like a radio cabinet, based on refrigeration technology. The machine, however, was bulky, costly, and required a separate, remote-controlled condensing device.
  • In the early 1900s, the first electric air conditioner circulated air through water-cooled coils. This was not created with the intention of providing human comfort. Rather, it was created to improve the image quality by controlling humidity around a printing press.
  • MIT engineers have devised a modern air conditioning system that employs sensors attached to aluminum rods suspended from the ceiling. These sensors are then activated by movement. To put it another way, the air conditioner just turns on when there are people present.
  • The adoption of HVAC equipment has increased as a result of factors such as technological advancements and climate change. The demand for air conditioning equipment has risen as a result of global warming, which has resulted in shifting and erratic weather conditions.
  • 3D printed air conditioners can become commonplace in the future, despite their rarity today. With rapid advancements in 3D printing technology over the last decade, it’s not unreasonable to expect 3D printed air conditioners to become more popular in the coming years.
  • Stuart Cramer is the first to coin the term “air conditioning” to describe this operation. He is a North Carolina textile mill engineer. He invents a system that adds water vapor to the air of textile plants. Humidity makes spinning yarn faster and less likely to split.
  • In 1939, the automobile manufacturer Packard began installing air conditioning systems (called “weather conditioners”) in its vehicles. This was the first car manufacturer to offer AC, but there was a company in New York that retrofitted ACs for cars as far back as 1933.  
  • The St. Louis World’s Fair organizers used mechanical refrigeration to keep parts of the Missouri State Building that hosted fair activities cool in 1904. It was capable of moving 35,000 cubic feet of air per minute and provided the public with the first taste of comfort cooling.

Strange Facts About Air Conditioner

  • Until the 1970s, most households did not have air conditioning. Most people couldn’t afford air conditioners until technical advances made them more affordable. Central air conditioning became more common in the 1970s. About 90% of homes in the United States have air conditioning.
  • Before air conditioning was invented, people used a variety of architectural styles to keep their homes semi-cool. One style, popular in the South, was the dogtrot house. This design featured a small cooking cabin separate from the main house but connected with an open-air corridor.
  • President James Garfield was assassinated in the summer of 1881. Engineers devised a makeshift air conditioner to keep him cool in an effort to alleviate his pain. They blew air over wet cloth-wrapped ice blocks. It was easy, but it was enough to keep Garfield alive for nearly 11 weeks.
  • Carrier Engineering Company installed the first air conditioning system in the West Wing of the White House in 1930, during Herbert Hoover’s presidency. In 1933, while Franklin D. Roosevelt was president, air conditioning units were installed in the private quarters of the White House.   
  • Since a two-stage compressor has two speeds to choose from, you can operate it at a lower speed when you don’t need as much cooling. This will also help to lower the temperature in the house, but it will do so by using less energy and giving the homeowner more control over the temperature.
  • Warmer states would be deserted if they didn’t have air conditioning. Can you imagine not having an air conditioner if you lived in Florida, Texas, or another hot climate? You’re not alone; as home air conditioning became more common, the population of these hotter states grew significantly.
  • William Carrier patented his “Apparatus for Treating Air,” which used cooling coils to either humidify or dehumidify the air using hot or cold water. He tested his technology, then designed and patented an automatic control device for textile mills that regulated humidity and air temperature.
  • In recent years, AC compressors have advanced greatly, providing yet another way to improve comfort and performance when cooling the home. Compressors have only had one mode in the past. This feature may be turned on or off. The compressor pumped cooled air around the house while it was working.
  • Air conditioning was first introduced in the House of Representatives in 1928, followed by the White House and the Senate in 1929. However, most Americans only experienced air conditioning during this period in locations like theaters or department stores, where it was seen as a pleasant novelty.

Fun Facts About Air Conditioner

  • Heat resistance is reduced by using an air conditioner. According to studies, as a person spends more time in an air-conditioned environment, his natural tolerance for heat decreases. So it’s no surprise that when we leave the mall or some other air-conditioned place, the feeling of heat doubles.
  • The construction sector’s productivity in the United States is projected to reach USD 1.58 trillion by 2028, according to the Bureau of Labor Statistics. The increased need to build and maintain the energy efficiency of existing systems is expected to drive substantial demand growth for HVAC services.
  • In the United States, the first residential air conditioning system was in the Charles Gates mansion. Built in 1913, this Minneapolis home was 38,000 square feet, and surprisingly, it was demolished in 1933 after the original owner died and no one wanted (or could afford) to buy a palatial home with AC.
  • Engineer Henry Galson went on to create a more portable, low-cost window air conditioner and set up production lines for a number of companies. By 1947, 43,000 of these devices had been sold, allowing homeowners for the first time to experience air conditioning without having to invest in costly upgrades.
  • In the 1840s, Dr. John Gorrie used ice from northern lakes to cool his hospital rooms in Florida. He believed that cooling was critical for reducing diseases such as malaria, and eventually, he invented a machine that created ice using water, wind, horses, and steam. That set the stage for modern cooling.
  • If the surface of the evaporator coil is slightly colder than the dew point of the ambient air, air conditioning equipment can decrease the absolute humidity of the air processed by the device. In an occupied room, an air conditioner built for that space can normally achieve a relative humidity of 30% to 60%.
  • The first air conditioner was a block of ice. People used to stay cool with large blocks of ice before air conditioners were invented to keep things nice and cool. In reality, the first air conditioners’ performance ratings were based on how much ice would have been needed to achieve the same cooling capacity.
  • Although it varies significantly by area and home size, the average American family spends about $2,200 on energy costs every year, and approximately 48% of those costs are for heating and cooling. Heating accounts for 42% of the total, while cooling only takes up just 6% of the average family’s energy budget.
  • In dry, hot climates, the evaporative cooling effect can be achieved by putting water near the air intake so that the draft draws air over the water and into the shelter. As a result, in the architecture of humid, arid climates, the fountain is often compared to the fireplace in the architecture of cold climates.
  • Dr. John Gorrie installs an ice-making system at the Florida hospital where he works, which compresses ice into buckets and then blows air over them. In 1851, he patented the idea, envisioning his invention as a way to keep buildings cool all over the world. His dream, however, fades away without financial backing.
  • The use of CFC and HCFC refrigerants causes ozone layer loss in our atmosphere, allowing harmful rays to reach our planet. To substitute refrigerants like R-11, R-12, and R-22, newer ozone-safe refrigerants have been created. In newer air conditioning systems, non-ozone-depleting refrigerants like R-410a have been used.
  • Air conditioning saves lives. An analysis of suicides in Toronto, Ontario and Jackson, Mississippi indicates that suicide rates increase with heat waves. Additionally, when people don’t have access to cooling, they become more likely to die. Tragically, 739 people who didn’t have AC died during a Chicago heat wave in 1995.

Unbelievable Facts About Air Conditioner

  • Passive air conditioning buildings are usually less costly to install and maintain than buildings with traditional HVAC systems that use less electricity. Although passive methods can achieve tens of air changes per hour and cooling of tens of degrees, site-specific microclimate must be considered, complicating building design.
  • Passive air conditioning buildings are usually less costly to install and maintain than buildings with traditional HVAC systems that use less electricity. Although passive methods can achieve tens of air changes per hour and cooling of tens of degrees, site-specific microclimate must be considered, complicating building design.
  • Air conditioning was not widely available in 1931, and only the richest people could afford individual room air conditioning. H.H. Schultz and J.Q. Sherman came up with the idea for these units, which sat on a window ledge and cost between $10,000 and $50,000. That’s the difference between $120,000 and $600,000 in today’s money!
  • Carrier publicly unveiled a new model of centrifugal chiller machine in May 1922 at the Rivoli Theater in New York, which had fewer moving parts and compressor stages than existing systems. The revolutionary device improved the efficiency and cost of large-scale air conditioners, allowing them to be used more widely throughout the world.
  • Over the next 30 years, demand for air conditioning is set to triple. Analysts predict that 5.6 billion buildings will have AC by 2050, and to make that happen, consumers need to buy 10 new air conditioners every second for the next 30 years. That’s the equivalent of 600 air conditioners every minute and 3,600 air conditioners every hour.
  • By 2009, 87 percent of American households had some kind of air conditioning. Despite the fact that air conditioning has offered much-needed relief from hot, humid summers, pollution from current air conditioners poses a danger to an ever-warming atmosphere. This translates to about 100 million tons of CO2 emitted into the atmosphere per year.
  • Although the upfront costs of a solar-powered air conditioner are normally higher than those of a conventional air conditioner, solar-powered air conditioning has the potential to save money over time. Solar-powered air conditioners harness the sun’s energy using rooftop panels. Solar energy is then used to power the HVAC system of the building. 
  • As air conditioning became more widely available in the early 1900s, movie theater owners invested in air conditioning systems to keep seats filled on the hottest days of the year. Since most people didn’t have air conditioning in their homes, going to the movies was a great way to unwind. The term “refrigerated air” was often used in theater ads.
  • Many homeowners overlook ventilation and temperature control. High ceilings, sleeping porches, breezeways, and transoms are no longer essential features for homes and other buildings to withstand the summer because of air conditioning. Unfortunately, missing any of these steps can be very inconvenient, especially if your air conditioner breaks down.
  • Carrier realized that extracting heat from the factory air would minimize humidity, so he borrowed technology from the fledgling refrigeration industry to produce what was, and still is, basically a hacked-up refrigerator. Air conditioning systems operate by inhaling warm air, moving it over a cold surface, and exhaling cool, dry air, just as they do now.

Facts About Air Conditioner for Kids 

  • Homes and buildings were built with high ceilings, breezeways, sleeping porches, landscaping to create shadows, and other features to keep residents cool before air conditioning. As air conditioning became the standard, architects stopped designing buildings for the purpose of cooling (making it that much harder when we have to go without air conditioning).
  • Air conditioners and allergies go together like peanut butter and jelly. Okay, they won’t taste as good as a PB&J, but air conditioners have been shown to help people with asthma breathe easier. What is the reason for this? Air conditioners can eliminate allergens and other tiny particles from indoor air, resulting in less sneezing and a more comfortable environment.
  • Evapolar, a Cyprus-based company, has released what it calls “the world’s first personal air cooler.” It’s a small cube with a water tank and a fan that purifies the air while creating a breeze. Evapolar advocates the concept of a “microclimate” designed to cool a single person’s work or sleeping area, rather than cooling whole rooms or buildings, to save electricity.
  • Excessive heat also reduces productivity. Based on research from NASA, telegraph operators make an extra five mistakes per hour when the temperature is 80 degrees and a stunning 60 mistakes per hour when the temperature is 95 degrees. Over time, the rate of errors increases, and at 95 degrees, operators start to make 138 mistakes per hour by the third hour in the heat.
  • With a smart thermostat, you can configure your air conditioner to keep your home at a warmer summer temperature while you’re at work. Smart thermostats attach to your tablet or smartphone, allowing you to control your home’s temperature from anywhere in the world. Programming a smart thermostat to automatically adapt to your personal preferences takes just a few minutes.
  • Geothermal air conditioning and heating uses the earth’s heat energy to heat and cool your home through an underground system (along with some familiar above-ground components). As compared to the temperature outside your house, the temperature underground remains relatively stable. As a result, it is a dependable source of heat energy for both the heating and the thermodynamic cooling process.
  • Fans were invented by the Chinese. The Chinese discovered that moving air has a cooling effect on the skin about 3000 years ago, and they developed a useful little device to generate moving air: the handheld fan. This is the world’s first portable air conditioner! Someone even made a rotary fan that was operated by hand. Fans are also an essential part of almost every air conditioning system today.
  • General Motors’ Thomas Midgley, Albert Henne, and Robert McNary developed chlorofluorocarbon (CFC) coolants, which were the world’s first non-flammable refrigerating fluids, significantly enhancing air conditioner safety. However, decades later, the contaminants were related to ozone depletion and were gradually phased out by governments all over the world following the Montreal Protocol in the 1990s.
  • Ice-powered air conditioning uses a thermal battery to reduce the cost of cooling a home or building. The thermal battery fills with water and freezes into a dense block of ice throughout the night. The ice block is used to keep the building cool throughout the day. Since ice-powered air conditioning reduces the need to use the air conditioner’s compressor, it uses less energy and lowers utility bills.
  • By upgrading your computer to “greener” technology, you can save energy and money. Heating and cooling account for almost half of the average family’s energy costs, which total nearly $2,000 a year. The Environmental Protection Agency (EPA) encourages homeowners to keep their homes cool by using energy-efficient cooling solutions. What exactly is the good news? These changes would allow you to save money.

Information About Air Conditioner

  • Air conditioners are capable of much more than just cooling the air. They often remove moisture from the air, making it more comfortable. Set your thermostat fan to “off” rather than “on” all day. Instead, choose the “auto” setting, which will only blow air while the cooling system is operating. Moisture would be blown back into the house and affect the humidity levels if you keep the fan on all the time.
  • Wearable technology is a novel way for HVAC technicians to easily and effectively inspect and service air conditioning systems. Although there are many different types of wearable devices, eyeglasses are one of the most common. If HVAC technicians need help when servicing a machine, these wearable devices give them real-time access to off-site experts, allowing them to diagnose and repair problems faster.
  • Growing government support in the form of higher budget allocations aimed at increasing homeownership and sustainable community development, as well as rising housing affordability, will help to fuel the sector’s growth. Furthermore, increased construction activities, rapid urbanization, infrastructural improvements, and HVAC unit replacements are some of the major factors driving the country’s HVAC services industry.
  • Summer blockbuster movies got their start thanks to air conditioning. In the summer, people often went to movie theaters to enjoy the air conditioning. Production companies took advantage of this fact, and they began to release their biggest hits in the summer. Although many people now have air conditioning in their homes and they no longer have to seek refuge from the heat at the theaters, the tradition continues today.
  • The first domestic air conditioner, which was over 7 feet high, 6 feet wide, and 20 feet long, was installed in 1914. People were willing to pay between $10,000 and $50,000 for one, despite its size. That would be between $120,000 and $600,000 in today’s money! Residential air conditioning systems were only available to the very rich. Think what a new HVAC system used to cost the next time you whine about how much it costs now.
  • The Cave Dwellers were the first to build homes that were cooled by geothermal energy. It is common knowledge that it is hotter underground and inside the planet. Years ago, perhaps about 10,000 BC, the first human hunter-gatherers found it out for us. Not only did they live in cool caves, but they also dug underground burrows to avoid the sun. Geothermal cooling is now the latest and best in cooling technology, after 12,000 years!
  • In a home with air conditioning, shades and blinds are your best friends. The explanation for this is simple: light is heat, and sunlight streaming in through your windows will gradually raise the room’s temperature. As a result, your air conditioners will have to work harder to keep the rest of your house cool, putting more strain on the machine. Make sure the blinds and curtains are closed on the next hot day when the sun is shining down.
  • Cooling towers were invented by Middle Eastern architects. Towers constructed over underground cool air channels were popular in traditional Middle Eastern building design for larger spaces. The towers were designed to capture and disperse cool breezes, as well as to pull cool air up from underground channels while forcing warm air out. While we have streamlined the idea to use cool water, large buildings are still cooled using “cooling towers.”
  • Because of its lower energy usage and environmentally friendly refrigerant, the DeVAP device is gaining popularity. DeVAP, which stands for desiccant enhanced evaporate, is an evaporative cooling device in which water is poured into a honeycomb media and a fan blows through it, allowing the water to evaporate. The desiccant material absorbs humidity from the cooled air, resulting in dry air and a cooling sensation close to that of a conventional air conditioner.

Interesting Facts About AC for Kids 

  • Many homes do not have working air ducts. Previously, this meant that homeowners had to rely on window air conditioners and portable air conditioners to keep cool. Today, however, you have the choice of going ductless! Indoor air handlers in a ductless system are installed high on the walls of various rooms in the building. Consider these to be the vents of a traditional air conditioner/furnace, but with the addition of a blower, coil, and other critical components.
  • Many buildings have an overall HVAC system that serves them, but there are troublesome areas that have different time and temperature specifications. Zone the system by adding different time and temperature controls for specific areas – zoned areas will have better conditions because inhabitants have more control over their respective environments. It’s also a good way to save money on electricity because HVACs in unused or unoccupied zones can be switched down or off.
  • Thermally powered air conditioning is another design that has recently been introduced. Chromasun, an Australian company, has developed a low-cost alternative to conventional air conditioners. It isn’t yet a commonly used technology, and it will be years before this type of design is widely available in the United States. Thermally powered air conditioning, on the other hand, is a highly versatile and powerful device that uses solar energy and is supplemented by natural gas.
  • The HVAC industry in the United States is moving toward smart technology, thanks to a high degree of IoT integration in the field. The market for HVAC services in the country is also governed by state policies and regulations. According to Aeroseal, LLC, furnaces in the northern US must have a 90 percent efficiency rating, but only an 80 percent efficiency rating is expected in the southern states. This suggests that local and regional regulations drive the HVAC services industry.
  • Water-cooled air conditioning was invented by the Egyptians. How clever do you have to be to find out how to build massive pyramids out of rock without using any power tools? Those Egyptians had a real knack for problem-solving, and you can bet the Nile River valley in Africa was scorching hot. So, in the absence of modern air conditioning, how did they remain cool? To keep the breeze out, they hung wet reeds in the walls. It was the first air conditioner with a water cooling system!
  • The word “Summer Blockbuster” was coined thanks to air conditioning systems. Movie theaters were one of the first companies to adopt air conditioning technology in the early twentieth century. Patrons flocked to movie theaters in the 1930s not only to enjoy the films but also to enjoy the cool air during the summer months. Marketers took advantage of this pattern and held off on releasing their major hits until the summer. As a result, the word “Summer Blockbuster” entered our lexicon.
  • Manufacturers of residential central air conditioners and heat pumps have been subject to Energy Department conservation requirements since 1992. From 1993 to 2023, the initial standard is estimated to save around $29 billion on energy bills. From 2006 to 2035, the standard is expected to save about $70 billion in electricity bills and prevent more than 369 million metric tons of carbon dioxide emissions, which is equal to the annual greenhouse gas emissions of around 72 million vehicles.
  • Air conditioning can help avoid heat stroke, dehydration from excessive sweating, and other hyperthermia-related problems in hot weather. In developing countries, heat waves are the most dangerous form of weather. In hospital operating rooms and other areas where a clean, dry, hypoallergenic atmosphere is vital to patient safety and well-being, air conditioning (including filtration, humidification, cooling, and disinfection) can be used to provide a clean, safe, hypoallergenic atmosphere.
  • Ducting mechanisms were invented by the Ancient Greeks and Romans. The Romans stepped up the game with their hypocaust scheme after the Ancient Greeks invented the concept of central heating and cooling using water piped from aqueducts. Mosaic tiled stone floors backed by columns could be found in their luxurious villas and public bathhouses. The room underneath was used to move heated air to warm the space, similar to how modern HVAC systems use ducts to transport heated and cooled air to the spaces that need it.
  • Packaged air conditioners (also known as self-contained units) are central systems that combine all of the components of a split central system into a single housing and distribute air to the spaces to be cooled, likely viaducts. They can be outdoors or indoors, on roofs (rooftop units), draw air to be conditioned from inside or outside a house, and be water, refrigerant, or air-cooled, depending on their design. Outdoor units are often air-cooled, while indoor units are frequently water-cooled using a cooling frame.
  • Prior to the invention of modern air conditioning, people used to cool their homes or businesses with ice, which was often harvested in one-ton blocks. As air conditioning manufacturers began to advertise their products, they wanted to use terms their customers could understand so they used the phrase “ice power” or referred to their systems as one-ton ACs. An air conditioner with a one-ton capacity essentially produces as much cooling as a melting ton of ice. To put it in modern terms, that’s equivalent to 12,000 BTUs.
  • The Victorians were well-versed in the subject of air movement. The Victorians were masters of both artistic and practical design. They were known for their rigid codes of conduct, but they were also masters of creative and practical design. They were well-versed in the use of airflow to increase comfort. High ceilings, covered porches to keep the sun out, and wide recessed windows for cross ventilation were all part of the plan. Airflow is still one of the most important components of today’s air conditioning systems for maintaining a cool and comfortable environment.
  • Packaged terminal air conditioners (PTACs), through-the-wall air conditioners, and window air conditioners all work in the same way. In cold weather, PTAC systems can be modified to provide heating, either directly with an electric strip, gas, or other heaters, or indirectly by reversing the refrigerant flow to heat the interior and draw heat from the outside air, effectively turning the air conditioner into a heat pump. They can be mounted in a wall opening with the use of a special sleeve on the wall and a custom grill that is flush with the wall, or they can be installed in a window without the use of a custom grill.
  • All new residential central air-source heat pump systems and air-conditioning sold in the United States will be expected to meet new minimum energy efficiency requirements and standards beginning in 2023. The most recent minimum energy efficiency standards for these equipment types took effect in 2015, and for the first time, separate standards were established for cooling central air conditioners sold in the southern and northern sections of the United States. The new regulations maintain different cooling efficiency standards for air conditioners in the south, as well as requiring all air-source heat pumps to improve their heating efficiency.
