The 2nd century Chinese inventor Ding Huane of the Han Dynasty invented a rotary fan for air conditioning, with seven wheels 3 m (9.8 ft) in diameter and manually powered. In 747, Emperor Xuanzong of the Tang Dynasty (618–907) had the Cool Hall (Liang Tian) built in the imperial palace, which the Tang Yulin describes as having water-powered fan wheels for air conditioning as well as rising jet streams of water from fountains.  During the subsequent Song Dynasty (960–1279), written sources mentioned the air conditioning rotary fan as even more widely used. In 1758, Benjamin Franklin and John Hadley, a chemistry professor at Cambridge University, conducted an experiment to explore the principle of evaporation as a means to rapidly cool an object. Franklin and Hadley confirmed that evaporation of highly volatile liquids such as alcohol and ether could be used to drive down the temperature of an object past the freezing point of water. They conducted their experiment with the bulb of a mercury thermometer as their object and with a bellows used to "quicken" the evaporation;

they lowered the temperature of the thermometer bulb down to 7°F while the ambient temperature was 65°F. Franklin noted that soon after they passed the freezing point of water (32°F) a thin film of ice formed on the surface of the thermometer's bulb and that the ice mass was about a quarter inch thick when they stopped the experiment upon reaching 7°F. Franklin concluded, "From this experiment, one may see the possibility of freezing a man to death on a warm summer's day".  Air conditioning makes deep plan buildings feasible, for otherwise they'd have to be built narrower or with light wells so that inner spaces receive sufficient outdoor air via natural ventilation. Air conditioning also allows buildings to be taller since wind speed increases significantly with altitude making natural ventilation impractical for very tall buildings. Comfort applications for various building types are quite different and may be categorized as Low-Rise Residential buildings, including single family houses, duplexes, and small apartment buildings, High-Rise Residential buildings, such as tall dormitories and apartment blocks, Commercial buildings, which are built for commerce, including offices, malls, shopping centers, restaurants, etc.,  Institutional buildings, which includes hospitals, governmental, academic, and so on, Industrial spaces where thermal comfort of workers is desired and Sports Stadiums - recently

, stadiums have been built with air conditioning to allow competition to take place in summer, such as University of Phoenix Stadium and in Qatar for the 2022 FIFA World Cup. In addition to buildings, air conditioning can be used for many types of transportation — motor-cars and other land vehicles, trains, ships, aircraft, and spacecraft. Process applications aim to provide a suitable environment for a process being carried out, regardless of internal heat and humidity loads and external weather conditions. Although often in the comfort range, it is the needs of the process that determine conditions, not human preference. Process applications include these are hospital operating theatres, in which air is filtered to high levels to reduce infection risk and the humidity controlled to limit patient dehydration. Although temperatures are often in the comfort range, some specialist procedures such as open heart surgery require low temperatures (about 18 °C, 64 °F) and others such as neonatal relatively high temperatures (about 28 °C, 82 °F), clean rooms for the production of integrated circuits, pharmaceuticals, and the like, in which very high levels of air cleanliness and control of temperature and humidity are required for the success of the process

, facilities for breeding laboratory animals. Since many animals normally only reproduce in spring, holding them in rooms at which conditions mirror spring all year can cause them to reproduce year-round and the aircraft air conditioning. Although nominally aimed at providing comfort for passengers and cooling of equipment, aircraft air conditioning presents a special challenge because of the changing density associated with changes in altitude, humidity and temperature of the outside air  Other  areas that use this type of air conditioning are data centers, textile factories, physical testing facilities, plants and farm growing areas, nuclear facilities, Chemical and biological laboratories, mines, industrial environments and food cooking and processing areas. Duct Sealing is the sealing of leaks in air ducts in order to reduce air leakage, optimize efficiency, and control entry of pollutants into the home or building. Air pressure combined with air duct leakage can lead to a loss of energy in a HVAC system and duct sealing solves issues of energy loss in the system.

Duct tape is not used for sealing ducts. Building codes call for special fire-resistant tapes, often with foil backings and long lasting adhesives. Signs of leaky or poorly performing air ducts include utility bills in winter and summer months above average relative to rate fluctuation spaces or rooms that are difficult to heat or cool duct location in an attic, attached garage, leaky floor cavity, crawl space or unheated basement.  Air Condition Miami: Duct Cleaning I was having problems with my dryer and the ducts. I was surfing the web to see if I could find someone that could fix the problem.  I was using this search engine and it got me in contact with a person that was very reliable.  He showed up on time and was done in a short amount of time.  I am very pleased with the work. Air Condition Miami:  Installation I was having my house built and it was time to have the air conditioner put in but I had no idea what to buy or how it would get done.  I can not be in this house with no a/c.

I was surfing the web and came across this company that walked me thru the steps of what they were going to do and the we able to add my dryer duct as well.  I was having problems breathing and thought my air ducts needed to be clean.  I used this site to find a company that would clean all of my ducts for a good cost.  The company I found was great and I am no longer having problems breathing. Air Condition Miami: Heating Repair The weather here has been brutal and cold and I went to turn on the heat and got a strange noise and smell.  I searched the web to see if someone would come out that day and man I did.  I was impressed with the service and they explained to me everything that was wrong and fixed it for a good cost. Air Condition Miami: Maintenance I was on a maintenance contract to keep my air conditioner/heater in top working order.  The company that I was using close and I had to shop for a new one.  I found this search engine and it got me to a company that was not only good but most of the people I dealt with were there.

That gave me a piece of mind. Air Condition Miami: Repair I got a shock when I got home from work and turned the air on to cool the house and the unit started to smoke.  I knew the unit was old but was hoping it would hold on for a few more months.  I started right then and there looking for a new unit.  I was using a search that got me a local dealership that went above and beyond what I thought. They came to my house the next day to see what I needed and I had cold air in no time.  Air Condtion Miami: Duct Cleaning I own a small apartment building in Miami and I wanted to redo the laundry room because it had been years since it had been done.  I crawled into the ceiling to check the duct work and it was filthy and damaged.  I was upset to let it get that bad but I did not know so I called a friend that told me about an site that would get me to someone that could help me and boy did it.  These guys were professional and cleaned and repaired the duct with minimal damage and dirt.
