Air Balancing – What It Is & When It’s Required

What it is

  • Measuring and verifying HVAC airflow
  • Confirms systems meet design intent
  • Required for compliant handover

Why it matters

  • Verifies performance before handover
  • Identifies airflow issues early
  • Supports compliance and defect resolution

When it’s required

  • Mechanical commissioning & handover
  • After system upgrades
  • To resolve airflow issues

Incorrect airflow commonly leads to compliance issues, defect rectification, and delayed handovers.

What’s Included in Our Air Balancing Service

Pre-Balancing & Setup

  • Pre-balancing checks (access, dampers, diffuser condition)
  • Review of design airflow and system intent
  • Identification of access or installation constraints

Testing & Adjustment

  • Airflow measurements at diffusers and grilles
  • AHU, FCU, and system-level airflow verification
  • Damper and volume adjustments where required

Verification & Handover Support

  • Re-testing to confirm final results
  • Final balancing confirmation
  • Clear issue notes for contractors and consultants

All work is performed using calibrated instruments and established testing and balancing procedures.

Your Deliverables – TAB Report (24-Hour Guarantee)

Every air balancing project includes a clear, structured TAB report delivered within 24 hours. Our reports are designed to be easy to read, practical on site, and suitable for project handover, compliance, and QA documentation.

What’s Included in the TAB Report

  • Design vs actual airflow comparison (per-outlet / system)
  • Summary page for fast visual review of system performance
  • Before and after balancing results (where applicable)
  • Pass / fail status against design airflow (colour coded)
  • Clear, contractor-friendly formatting
  • Notes on defects, limitations, or access issues

Clear & Contractor-Friendly TAB Report

Our TAB reports are structured for clarity, using visual airflow tables, design-vs-actual comparisons, and colour-coded pass/fail indicators.

Our TAB reports are suitable for project handover, commissioning documentation, and compliance records.

Air Balancing FAQs

What’s the difference between air balancing and commissioning?

Air balancing is a key part of HVAC commissioning. It focuses specifically on measuring and adjusting airflow, while commissioning covers broader system verification and performance checks.

What is a TAB report?

A TAB (Testing and Balancing) report documents airflow measurements, adjustments, and final verification against design values for HVAC systems.

How long does air balancing take?

Timeframes depend on system size and complexity. Most commercial air balancing works are completed within one site visit.

Do you guarantee a 24-hour TAB report?

Yes. All air balancing projects include a guaranteed TAB report within 24 hours of site testing.

Do you balance to design airflow or comfort?

We balance primarily to design airflow, while identifying issues that may affect comfort or performance.

What information is required before site attendance?

Mechanical drawings, diffuser schedules, and design airflow values allow for efficient testing and accurate reporting.

Can you troubleshoot airflow issues?

Yes. We regularly identify installation defects, access limitations, and system issues during testing and balancing.
