- Measure and interpret total external static pressure (TESP) and identify consequences of excessive pressure drop
- Perform visual duct inspections and recognize common defects including flex duct sagging, leaks, and undersized runs
- Calculate airflow using Pitot tube traverse, powered flow hood, temperature rise method, and face velocity measurement
- Diagnose filter-related pressure drop, register delivery problems, and duct system restrictions
- Apply proper measurement procedures including Pitot tube traverse patterns for round and rectangular ducts
- Select and use the correct tools for measuring static pressure and airflow in ductwork
- Interpret static pressure readings on both sides of the blower to identify restrictions
- Perform duct leakage testing at standard test pressures and calculate leakage as a percentage of system airflow
