When setting the indoor blower speed on an air conditioner, what is the recommended CFM of airflow per ton of cooling?

The recommended CFM (Cubic Feet per Minute) of airflow per ton of cooling for an air conditioning system typically falls within the range of 350 to 450 CFM. This range is considered optimal as it strikes a balance between efficient heat exchange and comfort in cooling.

When the airflow is set to approximately 400 CFM per ton, it helps ensure that the air conditioner operates at its designed efficiency while effectively distributing conditioned air throughout the space. Adequate airflow is critical not just for efficient cooling, but also for maintaining humidity levels and contributing to overall indoor air quality. Too little airflow can lead to poor performance and increased humidity, while too much can cause discomfort and inefficiencies.

Setting the indoor blower speed within this recommended range helps in optimizing the system's performance, achieving desired cooling results, and prolonging the life of the equipment.
