This course examines how Testing, Adjusting, and Balancing (TAB) professionals apply field experience and systematic troubleshooting methods to resolve HVAC performance issues after systems are placed into operation. Using real-world scenarios, the discussion highlights common causes of airflow and temperature deficiencies, including duct leakage, fan performance problems, coil bypass, and system bypass conditions. The article emphasizes investigative techniques rooted in TAB principles to distinguish true system deficiencies from design, installation, or operational issues. By documenting practical diagnostic approaches, the article demonstrates how experienced TAB professionals contribute to restoring system performance, maintaining design intent, and supporting long-term building operation.

Learning Objectives: 

• Identify common post-occupancy HVAC performance issues
• Describe TAB-based troubleshooting methods
• Recognize how installation and operational factors affect HVAC system performance.
• Differentiate between TAB-related issues and non-TAB root causes
