What does CFM stand for in HVAC systems?

In HVAC systems, CFM stands for Cubic Feet per Minute. This measurement is crucial as it indicates the volume of air that moves through the ductwork or vents within a building per minute. CFM is a key factor in determining the efficiency of heating and cooling systems, as it affects the comfort levels within spaces being conditioned. Proper airflow is essential for maintaining consistent temperatures and ensuring that air is being distributed effectively throughout the environment. Understanding CFM helps HVAC technicians size ducts properly, select appropriate fans, and ensure that the system operates as intended to provide comfort and air quality.

The other alternatives represent terms that are not commonly associated with standard HVAC terminology. Cubic Feet per Minute remains the accepted standard for describing air movement in these systems.
