What is the minimum cfm capacity for a heat pump in the cooling mode?

The minimum CFM (cubic feet per minute) capacity for a heat pump in cooling mode typically depends on the system's size and the specific cooling load requirements of the space. A general rule of thumb is to allow 400 CFM per ton of cooling capacity. Therefore, for a standard 2-ton heat pump, the minimum airflow would be around 800 CFM. However, it's essential to consider factors like duct design and home insulation to ensure optimal performance.
