Our Recent Job in Durham, NC: A Duct That Was Dirty All the Way Around
Most ducts we open have collected their dirt along the floor of the run, where gravity put it. This one had developed a thick, felt-like coating all the way around.
That happens when a line spends its life somewhere damp. A crawl space holds humidity, the inner surface never fully dries, and dust stops falling through and starts sticking wherever it lands, top and sides included. Plenty of Durham homes were built long before their HVAC was, and the ductwork ended up threaded through spaces that were never meant to carry it.
A supply run off Dellwood Drive, west of downtown. Drag the slider to compare the duct before and after cleaning.
