Air ducts in a house are typically situated in various areas, depending on the HVAC system’s design. You can commonly find them in ceilings, floors, and walls, depending on the ventilation and heating setup. They may also run through basements, crawl spaces, or attics. Often, the main trunk lines connect to the furnace or air handler in utility or mechanical rooms. In some homes, ducts may be hidden behind walls and ceilings. To pinpoint their location, inspect vents, registers, and areas around your HVAC system. Regular maintenance ensures efficient HVAC system performance and indoor air quality.
