Ductwork refers to the system of tubes or channels that transport air throughout a building. It is an essential part of heating, ventilation, and air conditioning (HVAC) systems, helping to distribute warm or cool air to different rooms. Properly designed ductwork ensures that every area receives the right amount of airflow, contributing to comfort and energy efficiency. Made from materials like metal or flexible plastic, ductwork can come in various shapes and sizes. Regular maintenance, such as cleaning and sealing, is important to prevent dust buildup and leaks, which can affect indoor air quality and the overall performance of the HVAC system.
