TAB -Testing Adjusting & Balancing
TAB -Testing Adjusting & Balancing

What TAB Means?

TAB is the commonly used acronym for the process known as Testing, Adjusting and Balancing. The objective of testing and balancing is to test, adjust and balance complete air and hydronic distribution systems. C&W-TESCO performs certified complete TAB of HVAC systems to ensure they perform as the engineer has designed and operate at optimum levels.

We also provide a comprehensive service that consists of a review of the design documents to determine “balance ability” of the engineer’s design, observation of the construction process, and a detailed procedure to test and balance all HVAC systems to achieve optimal performance with repeatable results.

The Design Phase

The Design Phase

During the design phase, the C&W-TESCO Testing and Balancing Engineer (TBE) works with the design team, contributing an analysis and suggestions through practical experience with various types of HVAC systems.

We also ensure the following during the design process:

  • That the contractor is informed of what they must accomplish before the project is handed over for TAB, any special testing that will be required is identified, and necessary training of personnel operating the HVAC systems is administered.
The Construction Phase

The Construction Phase

During the construction phase, C&W-TESCO develops a TAB Plan. The TAB Plan consists of submitting certified procedures for the engineer’s approval, creating forms based on submitted equipment specific to the project, and providing a “system readiness checklist” for the mechanical and controls contractors to review, ensuring all HVAC systems are ready for testing, adjusting and balancing.

C&W TESCO will visit the project during the construction phase to make observations of the ductwork, piping, building envelope, and HVAC equipment to determine proper installation.

The Tab Phase

The TAB Phase

During the TAB process, C&W-TESCO performs testing, adjusting, and balancing on all HVAC equipment and calibrates controls while producing a concise report for the entire HVAC system, reflecting design intent of the system and recorded performance data. Any system that is found to be deficient or performing outside of the designed tolerances is noted in the TAB report. After the report is completed and certified, it is offered to the engineer for verification and acceptance.
