Large-Scale TAB Services — Testing, Adjusting & Balancing

GENTAB performs large-scale Testing, Adjusting & Balancing (TAB) for the buildings and campuses where mechanical complexity is the norm rather than the exception. Our teams balance multi-air-handler systems, central heating and cooling plants, variable air volume networks, and high-volume exhaust and make-up air systems so that every zone receives the airflow and water flow its design calls for.

Balancing a large system is an exercise in interactions. Adjust one branch and you change the static pressure seen by every other branch; tune one pump and you shift flow across the entire loop. We work the system methodically — proportional balancing, duct traverses, pump and fan performance verification, and control-point confirmation — so the building reaches design conditions and holds them, not just at a single test point but across operating modes.

The result is documented, repeatable mechanical performance: measured airflow and water flow against design, identified deficiencies with practical recommendations, and a complete TAB report your commissioning agent, engineer, and owner can rely on. From data centers and hospitals to manufacturing plants and large institutional buildings, we bring the same disciplined methodology to projects of significant scale and complexity.

Air Distribution Balancing: Proportional balancing of supply, return, and exhaust across multi-AHU and VAV systems to deliver design airflow to every zone.

Hydronic System Balancing: Chilled water, hot water, and condenser water balancing to confirm each coil and terminal receives its design flow.

Central Plant Verification: Pump, chiller, boiler, and cooling tower performance verification to confirm the plant delivers capacity efficiently.

Fan & Pump Testing: Fan and pump performance measurement against curves to identify undersizing, riding the curve, and excess energy use.

Duct Traverse & Airflow Measurement: Pitot traverses and flow-hood measurement to quantify actual airflow and document it against engineered values.

TAB Reporting & Commissioning Support: Comprehensive, organized TAB reports that support the commissioning process and give owners a clear performance baseline.
