The present invention discloses an air vent cover for use in testing air leakage of an air duct system. The air vent cover includes a cover portion shaped to define a hollow cavity for enclosing an air vent. The air vent has a grill adjacent to a surface surrounding the air vent, and the grill has one or more louvers. The air vent cover includes a flexible connector extendable from the cover portion through the hollow cavity to the air vent. The flexible connector is removeably attachable to at least one of the louvers on the grill of the air vent. The flexible connector adjusts to secure an edge of the cover portion against a region of the surface surrounding the air vent, thereby creating a seal for inhibiting air flow through the air vent.
