Testing, adjusting, and balancing (TAB) services are essential not only at a building’s turnover but throughout its lifecycle. A detailed TAB report provides a snapshot of a building’s air and hydronic systems at a moment in time, documenting deficiencies, maximum and minimum airflows, and compliance with applicable standards. Unfortunately, many buildings encounter problems because initial TAB reports are neglected or because subsequent changes — like renovations or equipment upgrades — are not properly re-verified.

In this video from NFMT Baltimore, Mike Kelly and Jeremy Johnson from the Associated Air Balance Council highlight why TAB services are crucial for facility managers. Their presentation provides a comprehensive overview of maintenance programs, standards, and strategies to optimize building operations.

Facility managers must insist on a thorough TAB report as part of their O&M documentation. A properly executed report can reveal hidden issues early, helping prevent costly failures later. For ongoing operations, periodic testing — especially in healthcare, laboratories, and high-occupancy buildings — ensures continued compliance with ventilation standards like ASHRAE 62.1 and supports healthy indoor environments.

Maintenance programs are critical to the long-term health of mechanical systems. Proper filter management, water treatment for hydronic systems, inspection of cooling towers and humidification systems, and ensuring the integrity of sensors, fan belts, VFDs, and dampers are all examples of key maintenance considerations.
