Event Description

Duct Diagnostics: Evaluation & Troubleshooting for Real-World Systems is a building scientist–focused webinar that walks professionals through how to identify, evaluate, and troubleshoot common duct system failures found in existing homes. Using real-world field data and proven diagnostic concepts, this session explains how duct sizing errors, leakage, airflow restrictions, poor balance, and improper static pressure can reduce overall system performance by 40–50% and drive comfort complaints, oversized equipment, and costly callbacks. Attendees will learn how to interpret diagnostic data—including pressure pan results, static pressure readings, temperature rise, and room-to-room pressure imbalances—to understand what the duct system is actually doing and why it matters. The webinar emphasizes practical building science–based decision-making, helping participants recognize problem patterns, prioritize corrective actions, and clearly communicate findings—so issues are identified early, solutions are targeted, and whole-house systems perform as intended.
