Load & DesignQuestion 3 of 110
A common rule-of-thumb airflow value for a residential cooling system is approximately how many CFM per ton?
a.100 CFM per ton
b.400 CFM per ton
c.800 CFM per ton
d.1,200 CFM per ton
Explanation
Standard residential cooling airflow is roughly 400 CFM per ton, though it may range from 350 to 450 depending on climate and humidity. A 3-ton system therefore typically moves about 1,200 CFM. Correct airflow is essential for proper capacity and dehumidification.
