In a ceiling embedded indoor unit for an air conditioner, blower noise is prevented while maintaining a high air conditioning capacity. The ceiling embedded indoor unit is provided with a U-shaped heat exchanger placed in a casing embedded in a ceiling. The U-shaped heat exchanger includes two side portions, a portion connecting the side portions at one end, and blowers arranged in an inner space of the heat exchanger. A decorative panel is mounted to a lower surface of the casing that has two elongated air outlet ports in correspondence to the side portions of the heat exchanger and an air suction port formed between the air outlet ports. A control apparatus controls the number of rotations of the blower near the valley portion of the U-shaped heat exchanger to be higher than the blower near the open end.
