Duct connectors are essential components used in HVAC systems to join different sections of ductwork. They ensure that air flows efficiently from one part of the system to another, helping to maintain consistent temperature and air quality in buildings. These connectors come in various shapes and sizes to accommodate different duct types and configurations. Typically made from materials like metal or flexible plastic, duct connectors can be found in both residential and commercial settings. Proper installation of these connectors is crucial for preventing air leaks, which can lead to energy loss and increased utility costs.
