What is a disadvantage of ductwork in convection systems?

Ductwork in convection systems can be seen as a disadvantage due to its expense and size. Ducts typically require significant space within the walls, ceilings, or floors of a building, which can complicate the layout of interior spaces. This added complexity can lead to increased construction costs, both for the materials used to create the ductwork and for installation labor. Additionally, larger duct systems require more robust infrastructure to support them, further elevating costs.

In contrast, the other attributes mentioned, such as compact size and low cost, do not apply to ductwork in convection systems. Instead, ductwork tends to be bulky and can add substantial costs to a project. Although humidity control is essential in HVAC design, duct systems themselves can struggle with managing humidity levels effectively compared to other options like ductless systems or those that use alternative technology.
