What is the purpose of ductwork in an HVAC system?

The purpose of ductwork in an HVAC system is to distribute conditioned air throughout a building. This is a fundamental function, as ductwork serves as the network through which warmed or cooled air flows from the HVAC unit into different spaces within a structure. By effectively channeling this conditioned air, ductwork ensures that every area receives the appropriate amount of heating or cooling needed for comfort.

In an HVAC system, the conditioned air must move through the ducts without significant loss of temperature or pressure. This allows for an efficient and comfortable environment for occupants. Properly designed and maintained ductwork helps in achieving balanced airflow and maintaining energy efficiency.

While filtering air contaminants, increasing humidity, or absorbing excess heat can be associated with certain components of an HVAC system, these functions are not the primary purpose of ductwork. For example, air filters are typically separate components within the system, and humidity control may involve other devices like humidifiers or dehumidifiers, rather than the ductwork itself.
