Ceiling-mounted room cooling exhaust fan assembly

An assembly, comprising:

• at least one fan coupled to a fan housing that is supportable on a ceiling in an attic of a structure;
• the housing comprising an exhaust opening located in the attic when the assembly is mounted on the ceiling to exhaust air directly into the attic without passing through a conduit leading to an opening in the attic;
• a first damper in the housing between the exhaust opening and fan and movable under fluid pressure from an open configuration when the fan is actuated and a closed configuration when the fan is not actuated;
• a grill below the damper and coupled to the housing;
• and
• an outer peripheral flange on the housing and/or the grill and configured for flush mounting against a lower surface of the ceiling, the grill comprising plural air openings such that air in a room below the ceiling is exhausted through the grill into the attic when the fan is actuated and the assembly is mounted on the ceiling.

A method comprising:

• advancing a housing of a ceiling-mounted exhaust fan assembly upward through an opening in a ceiling into an attic above the ceiling until a bottom flange of the housing abuts a bottom surface of the ceiling;
• engaging a grill with the housing under the ceiling;
• and
• moving at least one ceiling flange coupled to the housing in the attic against a top surface of the ceiling to clamp the ceiling between the ceiling flange and the bottom flange of the housing.
