Commercial air balancing across Sydney & NSW

Flowtest provides independent commercial air balancing for offices, hospitals, schools, retail and industrial facilities throughout Sydney and regional NSW. Using calibrated instruments we measure and proportionally adjust airflow at every diffuser, grille and VAV box, so each zone receives its design airflow — the foundation of effective HVAC testing and balancing.

What HVAC air balancing involves

Air balancing on a typical Sydney building covers supply, return and exhaust air, fan and VAV performance verification, and pressure testing of ductwork. We record measured-versus-design airflows and issue witness-tested balancing reports your engineers and certifiers can rely on.

Why independent air balancing matters

As a fully independent balancing company our only goal is verified performance — comfortable, compliant and energy-efficient air distribution. Air balancing is often carried out alongside hydronic water balancing and full commissioning to recognised standards.
