Performing balance and troubleshooting on air and hydronic systems

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.

Components of the photo log FSD and damper functions have been sorted.

In addition to enhancing environmental performance and occupant comfort, the TAB services we provide contribute to a reduction in operating expenses for your property. Our team has over six decades of expertise, which allows them to grasp even the most complicated HVAC building systems. They also use the most up-to-date techniques and technology in order to properly and efficiently balance the entire system.

Testing for sound and vibration in HVAC systems

Local authorities, in addition to national organizations such as the National Fire Protection Association (NFPA) and the International Code Council (ICC), are the ones responsible for defining the standards and norms that apply to FLS systems. The owners of the facilities are the ones who are responsible for testing their systems at the right intervals and ensuring that they have the proper paperwork to demonstrate that their systems are functional.

Among the services we offer at HVAC TAB are HVAC system surveys.

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.

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.

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.

Generally, a tab is the same width as 4 to 5 spaces provided the font being used equally sizes each character. For example, the Courier font's tab equals 5 spaces, whereas the Arial font is 11 spaces to each tab when the font size for both is set to 12.

Use tabs to alternate between views within the same context, not to navigate to different areas. This is the single most important point, because staying in place while alternating views is the reason we have tabs in the first place. 

TAB stands for Testing, Adjusting and Balancing for HVAC systems. It refers to the steps taken by HVAC contractors to calibrate the HVAC unit in commercial establishments to achieve optimal performance and air quality.
