Air ducts are a system of pipes or conduits that are used to circulate air throughout a building or other enclosed space. They are typically made of sheet metal, fiberglass, or flexible plastic and are designed to deliver heated or cooled air from a central heating, ventilation, and air conditioning (HVAC) system to the various rooms and areas of a building.
The air ducts may also be used to remove stale air and excess moisture from the building, and to introduce fresh air from outside. The ductwork typically includes air filters, dampers, and other components to regulate the flow of air and maintain a comfortable indoor environment.
Properly designed and installed air ducts are important for ensuring good indoor air quality and energy efficiency in buildings. Poorly designed or installed ductwork can result in air leaks, reduced efficiency, and increased energy costs, as well as potentially harmful indoor air pollutants.
Air ducts need to be cleaned every few years.
