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 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 – easy to read, practical on site, and suitable for project handover, compliance, and QA documentation.

Frequently Asked Questions
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.
