AnswersDriveYou can affect the air movement by setting the fan to auto or on. When the fan is in the auto mode, the air conditioner moves air only when the cooling part is running. Since your AC is responsible for doing two jobs, cooling and dehumidifying, moisture from the air condenses on the cold evaporator coil when it runs.

What is an HVAC fan?
HVAC fans and blowers can be mounted to an exterior wall (ventilation unit) or above the ceiling (plenum fan), or used as part of a ducted system (duct fan). The fan spins or the blower turns by means of an electric motor, thus creating unidirectional air flow. Often, the air is pre-heated or cooled.

Do air conditioners bring in fresh air?
The closed setting brings in air from the room. With most air conditioners, you don't have to use the cooling function - you can use it just a fan. So if you don't have the cooling function on, you can bring in air from the outside, just like a fan does. The air conditioner cools you when it draws you in from the room.
