What must cleanouts be provided with to allow cleaning and inspection of the duct?

Cleanouts are essential components of duct systems as they provide access points for cleaning and inspection, ensuring that ducts maintain airflow efficiency and hygiene. The requirement for cleanouts to be equipped with access facilities allows technicians to reach into the ducts without needing to disassemble sections of the ductwork. This accessibility is crucial for maintaining the system, as it enables the removal of debris, dust, and other contaminants that can accumulate over time and impede airflow, or worse, pose fire hazards.

Providing access is a standard practice in various codes, including the North Carolina Mechanical Code, which highlights the importance of regular maintenance and inspection of HVAC systems. By ensuring that cleanouts are properly located and accessible, the system’s overall performance can be optimized, and the longevity of the equipment can be enhanced.
