What is the primary purpose of duct systems in HVAC?

The primary purpose of duct systems in HVAC is to distribute heated or cooled air throughout a building. Ducts are an integral part of central heating and cooling systems, allowing conditioned air from the furnace or air conditioner to reach different areas of the structure efficiently. This distribution is essential for maintaining comfortable indoor temperatures and ensuring that every room receives the necessary airflow for optimal climate control.

Effective duct systems are designed to deliver air evenly and minimize energy loss, which can be crucial for maintaining energy efficiency. The layout and materials used in ductwork also play a significant role in the system's overall performance.

In contrast, the other choices do not align with the function of duct systems: storing refrigerant pertains to refrigeration systems, providing water supply is related to plumbing, and eliminating air pollutants involves air filtration systems rather than ductwork. These distinctions help clarify the specific role that duct systems play within an HVAC framework.
