What does the airflow measurement "CFM" represent?

CFM stands for Cubic Feet per Minute, which is a measure of the volume of air that flows through a given space in one minute. This measurement is crucial in the heating, ventilation, and air conditioning (HVAC) industry as it helps determine the efficiency and capacity of heating and cooling systems. Proper airflow is essential for comfort and system effectiveness, as it impacts how evenly conditioned air is distributed throughout a space.

Understanding and measuring CFM is important for selecting the right HVAC equipment, assessing system performance, and ensuring adequate ventilation. By measuring CFM, technicians can evaluate ductwork, diagnose airflow issues, and make adjustments to optimize system operation.
