What is the main distribution system for forced air heating and cooling systems?

The main distribution system for forced air heating and cooling systems is ductwork. Ductwork refers to the network of tubes or channels that transport heated or cooled air from the HVAC equipment to various areas of a building. This system is essential because it efficiently delivers conditioned air to ensure comfort throughout different spaces, enabling temperature regulation and air distribution within homes and light commercial establishments.

Ductwork is designed to optimize airflow, minimize energy loss, and maintain indoor air quality by ensuring that all areas receive appropriate air circulation. Each section of ductwork is connected, allowing the system to be balanced for efficient performance. This contrasts with other options like coils or ventilation ducts, which may be involved in the overall HVAC system but do not serve as the primary means of air distribution. Airflow channels, while related, are not the accurate terminology typically used to define the structured components that make up the forced air heating and cooling distribution system.
