AABC recommends that engineers specify an independent test and balance agency for all projects to avoid potential conflicts of interest. The association has developed the following detailed TAB specifications to ensure that you get the most of the test and balance process.
An independent Testing and Balancing Agency certified by the AABC shall be engaged to Test and Balance the HVAC systems. Systems shall be balanced to plus/minus 10% of design requirements. The contractor shall place all systems and equipment into full operation for Testing and Balancing. One copy of the final Test and Balance report with the AABC National Performance Guaranty shall be sent directly to the engineer of record. Provide five (5) additional copies to the contractor.
