AC or Air Conditioning is the term used for the mechanical process for controlling the humidity, temperature, cleanliness, and circulation of air in buildings and rooms. In the process, dust, soot, and pollen are filtered out and the air may be sterilized. This can be achieved using portable air conditioning units, dehumidifiers or humidifiers or built in ventilation and AC systems that require ductwork and a central processing unit.
