What is the primary function of ductwork in HVAC systems?

The primary function of ductwork in HVAC systems is to distribute conditioned air throughout a building. This role is critical because, after air is heated or cooled by the HVAC system, it must be effectively transported to different areas of the building to maintain a comfortable and consistent indoor environment. The ductwork acts as a network that carries this air to various rooms, ensuring that occupants experience the desired temperature and air quality.

While ductwork can indirectly contribute to aspects such as supporting structural integrity or enhancing the aesthetic appeal of a space through its design, these are secondary functions and not the primary purpose of ductwork. Additionally, ductwork is typically not designed to filter out air pollutants; that role is handled by different components within the HVAC system, such as air filters. Thus, the central role of ductwork firmly lies in the distribution of conditioned air, making option A the correct answer.
