In relation to HVAC systems, what does CFM stand for?

CFM stands for Cubic Feet per Minute, which is a standard unit of measurement used in HVAC systems to quantify the volume of air delivered or moved by an air handler, duct, or ventilating device. This measurement is crucial for assessing the airflow rates in residential, commercial, and industrial HVAC systems. Understanding CFM is essential for ensuring adequate indoor air quality, comfort, and energy efficiency, as it directly relates to how effectively a heating or cooling system can maintain desired temperatures within a space.

When evaluating HVAC design and performance, knowledge of CFM allows technicians to size equipment properly, balance airflow throughout different areas of a building, and determine the efficiency of air distribution methods. Therefore, having a strong grasp of what CFM represents helps professionals optimize system performance and troubleshoot issues related to airflow.
