A booster fan and deflector for placing over a forced air heating/air conditioning floor vent to deliver more cool air in warm weather and more warm air in cold weather. The booster fan and deflector comprises a low profile plastic housing adapted to sit on a rectangular floor vent and blow air from the furnace air duct through a circular rotatable deflector on the top. A thermostatic switch is employed to automatically turn the fan motor on and off.
