Where should ducts be supported to ensure compliance with installation standards?

Ducts should be supported at intervals not exceeding 10 feet to comply with installation standards. This requirement ensures that the ducts maintain proper structural integrity, preventing sagging or bending that could lead to airflow restrictions or damage. Adequate support is essential for maintaining the efficiency of the HVAC system and ensuring safety during operation.

While joints and specific guidelines are important in duct installation, relying solely on those aspects may not provide sufficient support across the entire length of the ductwork. Establishing intervals for support—typically no more than 10 feet apart—ensures that ducts can withstand the weight of the material and resist any vibration or flexing that may occur during operation. In effect, this approach helps maintain optimal performance and longevity of the duct system.
