A duct chase is a vertical or horizontal enclosed space within a building that is designed to accommodate heating, ventilation, and air conditioning (HVAC) ductwork. It is used to conceal HVAC ducts from view by routing them through walls, floors, or roofs. The purpose of a duct chase is to provide a clear air pathway for HVAC systems without interfering with other components of the building. They are also known as duct shafts or mechanical chases and are used in both residential and commercial buildings. They are typically constructed of drywall or other fire-resistant materials and are designed to be easily accessed for maintenance and repairs. Overall, duct chases help to improve air quality and comfort while enhancing the aesthetic appeal of the building.
