Ductwork refers to a system of air passages designed to distribute air around a building or industrial plant. The word "ductwork" is often used interchangeably with ducting, air tubes, or HVAC (Heating, Ventilation, and Air Conditioning) system components. Other synonyms of ductwork that are commonly used include air ducts, ventilation ducts, exhaust vents, and chimney flues. Ductwork is vital in maintaining indoor air quality and regulating temperature, hence the need for efficient, well-designed ductwork systems. These words are used to describe the intricate network of pipes, plenums, dampers, and connectors that make up the pathways by which air moves in buildings.
