What is the primary purpose of ductwork in an HVAC system?

The primary purpose of ductwork in an HVAC system is to distribute conditioned air throughout a building. Ducts are essential for ensuring that heated or cooled air effectively reaches various rooms and areas, providing comfort to occupants. They help maintain a consistent temperature throughout the space by allowing the air to flow from the HVAC unit to different parts of the building.

While ductwork can have secondary functions such as reducing noise or influencing indoor air quality, these are not its main role. Ducts are not designed to contain refrigerants, as that function is typically managed by pipes used in refrigerant lines for cooling systems. Thus, the central function of ductwork remains as the channel through which air flows, directly impacting the overall efficiency and comfort of an HVAC system.
