How HVAC Ducts Work?

HVAC air ducts operate as a continuous loop. Air from the centrally located AC unit or jug flows through supply ducts and into the rooms. Then this air returns to the central unit through the return duct.

supply channels

Supply channels blow hot air or cold air into the rooms. Supply channel registers should be in most rooms of the house, although some rooms may not be serviced. Supply registers are covered with plastic or metal mesh and are located on the floor, exterior walls, ceiling or under windows. Supply ducts are cleaner than return ducts because the air first passes through a filter before making its way to various supply stores throughout the house.

Return air channel

A large return air vent removes air from the rooms and returns it to the AC system or furnace. The return is usually located in the wall near the floor level. The return air duct is always dirtier than the supply ducts because dirty and unfiltered air from inside the house leaves the return duct on its way back to the HVAC system.
