What is the goal of Testing, Adjusting, and Balancing (TAB) in HVAC systems?

The goal of Testing, Adjusting, and Balancing (TAB) in HVAC systems is fundamentally about ensuring that the system operates according to the design specifications set forth during the planning phase. This process involves carefully measuring and adjusting the airflow and water flow in each component of the system to achieve optimal performance. It validates that the HVAC system is functioning as intended by distributing air and temperature uniformly throughout the space, maintaining comfort levels, and operating with efficiency.

TAB ensures that systems are not only installed correctly but also perform within the parameters that provide energy efficiency and comfort control. By verifying that the design specifications are met, the process helps to identify any potential issues that could arise from improper installation or equipment malfunction. This is crucial for the long-term operation of the HVAC system and for meeting the performance expectations outlined in the design documentation.
