CFM testing stops airflow guesswork. This practical Australian guide shows how to measure air velocity with an anemometer, calculate CFM using area, and get repeatable supply and return readings you can trust. Learn the simple field method, common mistakes that ruin results, and how Aussie conditions like Brisbane humidity and coastal corrosion can make airflow faults show up fast.

Struggling with uneven temperatures and poor airflow? This guide breaks down HVAC air balancing, including how to measure CFM, when to use anemometers vs airflow capture hoods, and how proper balancing improves system efficiency, comfort, and performance.
