HVAC vents are typically located in the ceiling or walls of a room. The vents are connected to the HVAC system’s ductwork, which is responsible for distributing air throughout the building. The vents are designed to direct the air flow in a specific direction, usually towards the center of the room. Depending on the type of HVAC system, the vents may also be adjustable, allowing you to control the direction and intensity of the air flow.
