Ducts shall be supported with approved hangers at intervals not exceeding _____.

The maximum interval at which ducts must be supported with approved hangers is established to ensure the safety and integrity of the HVAC system. Supporting ducts appropriately helps prevent sagging and potential damage to the ductwork, which can lead to decreased efficiency and airflow issues.

In Kentucky, the regulations specify that ducts need to be supported at intervals not exceeding 10 feet. This standard is in place to ensure that the weight of the ductwork, particularly with the added burden of insulation and any contaminants, does not cause it to bend or break over time. Maintaining this support interval promotes proper function, efficiency, and durability of the entire HVAC system.

Understanding these standards is crucial for HVAC professionals to ensure compliance with local codes and to promote safe and effective HVAC installations.
