A shutter assembly for an intake opening in an exhaust fan for improving heating and cooling efficiency of a structure by preventing air in the structure from flowing through the exhaust fan and out of the structure. The shutter assembly for an intake opening in an exhaust fan includes a door for selectively positioning over an air intake opening in an exhaust fan. The door is mountable on the surface round the exhaust fan by at least one hinge member. The hinge member may be mounted on the door for pivotally coupling the door to the surface around the exhaust fan such that the door is pivotable between an open position and a closed position. A locking assembly is mounted on the surface and releasably couplable to the door for selectively securing the door in the closed position.
