The primary reason for performing a duct traverse is to calculate the average volume of air in cubic feet per minute (CFM) flowing through the duct. This process involves taking multiple measurements at different points across the duct's cross-section. By averaging these readings, technicians can obtain a reliable estimate of the air flow within the duct system.

This measurement is crucial for assessing system performance and ensuring that the HVAC system is delivering the proper amount of conditioned air to each space. It also helps determine whether the system is operating efficiently or if adjustments are necessary, such as resizing ducts or balancing airflow to achieve optimal comfort and energy efficiency.

While assessing insulation integrity, measuring static pressure, and determining air pressure are important components in HVAC diagnostics, they are not the primary focus of a duct traverse. A duct traverse specifically targets airflow measurement, making the determination of average volume flow (CFM) the correct and most relevant answer in this context.
