Generated explanation

A house cross-section illustrates several ways air can be removed from the interior, causing depressurization. An attic air-conditioning system has leaking ductwork, with arrows showing air escaping into the attic. A bathroom exhaust fan vents through the roof, while a central vacuum system and clothes dryer discharge through the exterior wall. A range hood above the stove also exhausts air outdoors. Arrows and dashed circles highlight the air-removal equipment and duct leakage locations.
