Abstract: An air conditioner is disclosed. The air conditioner may include a case including an inlet and an outlet formed therein, a blowing fan disposed in the case to blow air from the inlet to the outlet, a heat exchanger disposed in the case to exchange heat with air flowing in the case, a drain pan disposed below the heat exchanger to collect condensed water falling down from the heat exchanger, a drain pump disposed on one side of the drain pan to discharge condensed water collected in the drain pan to the outside of the case, and a water level switch configured to operate when a level of the condensed water reaches a reference level. When the level of the condensed water reaches the reference level, the drain pump is turned on.
