Air handler dampers are one of the most essential components of an HVAC system. They control the flow and volume of air to a building, allowing for better airflow, efficient filtration, and improved thermal comfort. Operating as a mechanical gate between supply and return air systems, air handler dampers regulate air using actuators that open and close in response to environmental demand signals. Without them, it would be impossible to effectively control temperature, humidity, and ventilation requirements. By properly adjusting and maintaining your air handler dampers, you can ensure the safe and effective operation of your HVAC system.
