Which trade is responsible for fabricating and erecting air distribution duct work?

The correct answer is that Sheet Metal Workers are the trade responsible for fabricating and erecting air distribution duct work. This specialization involves working primarily with metallic materials to create duct systems that facilitate the movement of air in heating, ventilation, and air conditioning (HVAC) systems.

Sheet metal workers have the skills and tools necessary to cut, shape, and assemble sheet metal into ductwork, ensuring it meets specifications for airflow and efficiency. They understand how to navigate building codes and standards related to air distribution systems and often work closely with HVAC technicians to install the ductwork properly as part of a larger system.

HVAC Technicians, while they play a crucial role in installing and servicing heating and cooling equipment, typically focus on the operational aspects rather than fabricating the actual ductwork. Pipefitters concentrate on the installation and repair of pipes used for gas, water, and other fluids rather than air distribution, and insulators deal primarily with insulating materials rather than fabricating or erecting ductwork. Thus, the role of the sheet metal worker is distinct and specialized within the HVAC industry.
