Testing, Changing, and Balancing is an acronym that stands for Testing, Adjusting, and Balancing, and it refers to the process of monitoring and adjusting the flow of air and water to satisfy design criteria. The TAB process involves employing test instruments, sensors, and monitors to check suitable temperatures, airflow, and other parameters inside the HVAC system. This is done in order to complete the TAB process. In order to ensure that heating, ventilation, and air conditioning (HVAC) systems are optimized for occupant comfort, energy efficiency, indoor air quality, and manufacturing processes, testing, adjusting, and balancing is a crucial step for complex air and hydronic systems found within buildings and throughout campuses.

The year 2003 marked the beginning of NorthWest Engineering Service Inc.'s work on FLS systems. Because of our extensive experience in Commissioning (Cx) and Testing, Adjusting, and Balancing (TAB), we are in a truly unique position to carry out audit surveys of HVAC systems, identify and functionally test all Fire Smoke Dampers, and offer documentation to meet the standards of the AHJ.

The majority of the work performed by the TAB consists of testing, measuring, and determining performance benchmarks. Among the most important examples of these operations are determining the air and hydronic volumetric flow rates, determining the level of heat transfer performance, and modifying the air exchange and ventilation rates.

The installation of fire and life safety (FLS) systems is an essential part of both new and existing building. Fire Smoke Dampers (often abbreviated as FSD) are among the most important of them. These devices are installed wherever a heating, ventilation, and air conditioning (HVAC) duct penetrates a fire-rated wall, ceiling, or floor. In the event of a fire, these devices should be able to stop flames and smoke from spreading through the HVAC ductwork, allowing occupants more time to evacuate the building and contributing to the reduction of the amount of damage caused by the fire. However, as buildings and systems age and as physical, mechanical, or electrical problems emerge, dampers can become inoperable. This leaves the duct as an open channel for fire and smoke in the event of a fire, and the facility runs the danger of being shut down owing to a lack of compliance. Verifying and documenting that essential FLS building systems perform as expected is accomplished through the process of testing and maintaining fire smoke dampers.

Frequently Asked Questions

Testing, Adjusting, and Balancing is a vital step for complex air and hydronic systems within buildings and throughout campuses to ensure HVAC systems are optimized for occupant comfort, energy efficiency, indoor air quality, and manufacturing processes.

What is TAB? TAB stands for testing, adjusting and balancing of your environmental systems and compressors. The testing part includes the use of specialized equipment to take precise measurements of how your system is operating. 

First, locate the closest supply air duct to your indoor AC unit. Then use a thermometer, even a refrigerator thermometer will work, and tape it just inside. Let your Air Conditioning run for about ten minutes then check and record the temperature.
