Our TAB Services

Each service is performed using calibrated field instrumentation, with results documented in a certified TAB report.

Air Balancing

Measurement and adjustment of supply, return, and exhaust airflows at every terminal device to verify that each zone receives the design airflow rate.

  • Airflow measurement at all terminal devices
  • Supply and return air balancing
  • Outside air verification
  • Fan performance testing
  • Exhaust system testing
  • VAV system verification

Hydronic Balancing

Testing and adjustment of chilled water, heating hot water, and condenser water systems to deliver the correct flow rate to every terminal unit.

  • Water flow rate measurement
  • Pump performance verification
  • Pressure differential balancing
  • Chilled and hot water system testing
  • Heat exchanger flow verification
  • Hydronic system documentation

Air & Hydronic System Surveys

A field assessment of existing air and hydronic systems to document current operating conditions, identify performance issues, and determine the scope of any corrective work needed.

  • Visual inspection of air and hydronic equipment
  • Spot measurements of airflow and water flow rates
  • Comparison of existing conditions to original design intent
  • Identification of comfort, energy, or performance deficiencies
  • Evaluation of equipment condition and operating parameters
  • Summary report with findings and recommendations

Duct Leakage Testing

Pressurization testing of supply, return, and exhaust ductwork to measure air leakage and verify compliance with project specifications and energy code requirements.

  • Calculation of allowable duct leakage rates
  • Duct pressurization to specified test pressures
  • Air leakage measurement using a calibrated orifice plate
  • Verification of measured vs. allowable leakage
  • Testing in accordance with project requirements
  • Detailed duct leakage test reports

How We Work

Our TAB Process

A systematic approach following NEBB procedural standards ensures thorough, accurate results on every project.

01

Project Review

We review design documents and coordinate with the project team to understand system design intent before mobilizing.

02

Field Testing

Certified technicians perform precise airflow and hydronic measurements using calibrated instrumentation.

03

System Adjustment

Dampers, balancing valves, and equipment are adjusted to achieve specified flow rates and design conditions.

04

Certified Report

A NEBB-compliant report documents all design values, measured conditions, and final adjusted readings.
