The primary function of a fan in an HVAC system is to move air throughout the system. Fans play a crucial role in ensuring that conditioned air, whether heated or cooled, is effectively circulated within the building spaces and across the heat exchangers or cooling coils. By facilitating airflow, fans help distribute air evenly, maintaining comfort levels in different areas of a building. They are also essential for exhausting stale air and drawing in fresh air, which contributes to overall indoor air quality.

While controlling humidity, heating air, and filtering dust are important components of an HVAC system, these tasks are typically managed by other system elements, such as humidifiers, heaters, and filters. Fans specifically focus on the movement of air, making them vital for the overall efficiency and effectiveness of heating, ventilation, and air conditioning functions.
