Air handling is a term used to describe the process of controlling and circulating air within a building. It involves the management of temperature, humidity, air quality, and air movement to ensure a comfortable and healthy environment for occupants. Air handling systems are used in both residential and commercial buildings, and typically include components such as air filters, fans, and dampers. These components work together to move air through the building, while also controlling the temperature, humidity, and air quality. Air handling systems can also be used to provide ventilation, which helps to reduce the buildup of indoor pollutants and improve air quality. In addition, air handling systems can help to reduce energy costs by controlling the temperature and humidity levels in the building. Air handling is an important part of any building’s HVAC system, and can have a significant impact on the comfort and health of the occupants.
