Listing ID #3189601

An air duct is a square or round hollow conduit or tube usually made of sheet metal. The purpose of an air duct is to carry cooled or heated air into rooms. The ducts usually form part of a home or building's air conditioning and ventilation systems. When the air is carried through the air ducts, vents are strategically placed in rooms that require heating or cooling. The hot or cold air carried through the air duct blows out of these vents, providing a temperature adjustment to the room. In many cases, vents can be opened or closed at will to determine whether air will leave the air duct or continue through the ducts. the ducts are located out of site in walls or along the ceiling. The main heating and cooling source of the building is connected to air ducts. This cooling or heating source produces heat energy. The energy is pushed up through the air ducts, and is carried elsewhere in the building as a result of pressure.-GISS, PVC Spiral & Rectangular Duct.
