What is CMH in HVAC?
The cubic feet per minute (cfm) and the cubic meter per hour (cmh) are the units of volumetric capacity. Knowing an HVAC unit's CFM or CMH provides insight into its cooling capacity relative to the size of the room. CMH is important to consider when purchasing a new HVAC unit or evaluating the effectiveness of your current cooling system.
