Air Ducts are associated with Heating, Ventilation and Air Conditioning System (HVAC); they are the pathway for Heated/Cooled air to travel throughout a house/building/tower.
Ducts are usually located within the walls, floors or ceilings. Usually we only see the outlet which is register covered with a grille. The purpose of a duct system is to transmit air from the central air source to the air diffusers located in the building control zones.
DVAC takes a leading role in designing and fabricating Rectangular and Square Ductworks.
