The air conditioner may include an indoor motor configured to drive a fan to blow indoor air and an outdoor motor configured to drive a fan to blow outdoor air. In addition, the air conditioner may include a controller configured to set a rotational speed of the indoor motor to drive a fan to blow indoor air based on operation modes and a maximum rotational speed of the outdoor motor to drive a fan to blow outdoor air and change a rotational speed of the outdoor motor within a range not exceeding the maximum rotational speed based on indoor environment information and a user-set value.
