In a split AC system, fresh air does not typically enter directly into the indoor unit, as these systems are designed to recirculate the air already present in the room. However, some split AC models come with an option for fresh air intake, allowing a certain amount of outside air to mix with the recirculated air. This feature can help improve indoor air quality but may reduce overall cooling efficiency. If fresh air is crucial, consider using a separate ventilation system alongside the AC.
