In order for your building’s environmental systems to function according to plan, it is extremely important to make use of a Testing, Adjusting and Balancing (TAB) specialist. A certified Testing, Adjusting and Balancing (TAB) service will ensure that your system is installed properly and operating within the allowable parameters for best efficiency and performance. This guide will walk you through the ins and outs of Testing, Adjusting and Balancing (TAB) and why it is so crucial for your business.
What’s Testing Adjusting Balancing (TAB)
TAB stands for Testing, Adjusting and Balancing (TAB) of your environmental systems. Testing, Adjusting and Balancing (TAB) is a systematic process or service applied to heating, ventilation, and air conditioning (HVAC) systems and other environmental systems to achieve and document air and hydronic flow rates.
The testing part includes the use of specialized equipment to take precise measurements of how your system is operating. These numbers are compared to the manufacturer’s specifications to determine whether the system needs to be adjusted. In the adjusting stage, the technician will inspect all aspects of how the system was installed and make minor adjustments where necessary to bring the installation up to the minimum standards for operation. Adjustments may come in many forms, some very simple and others more involved. Once the system has been adjusted, it must be rebalanced.
Balancing means that the technician will test the performance of all equipment working together to ensure that each component is operating at peak efficiency without interfering with any other component.
The following are main objectives of HVAC Test, Adjust and Balance Testing, Adjusting Balancing (TAB) procedure:
- Balancing air and water (if applicable) flow rates
