Testing & Inspection
The right air, in the right room, at the right pressure.
An HVAC system is only as good as its balance. We measure airflow at every terminal, adjust dampers, fan speeds and valves, and verify room pressure relationships and air-change rates — essential for isolation rooms, operating theatres, cleanrooms and labs, and the fastest route to comfort complaints disappearing in offices.

Even comfort
Ends hot and cold spots by delivering design airflow to every zone.
Correct pressure regimes
Negative and positive pressure rooms verified and documented.
Energy savings
Fans and pumps tuned to actual demand rather than running flat out.

How we work
Our process
- 01
Review design
Design airflows, ACH and pressure targets are taken from drawings and standards.
- 02
Measure
Calibrated hoods, anemometers and manometers record actual values.
- 03
Adjust
Dampers, fans and valves are set until readings meet design tolerance.
- 04
Certify
A TAB report records final values for commissioning and handover.
