Proper airflow is the backbone of high-efficiency HVAC performance, but you don't always need an expensive flow hood or velometer to measure it. In this quick guide, learn the precise formulas and step-by-step setup required to calculate Cubic Feet per Minute (CFM) using basic field measurements like voltage, amperage, and temperature rise. Perfect your diagnostics, eliminate airflow guesswork, and ensure your system is hitting that target.
