What is the generally accepted range for evaporator airflow in CFMs per ton of residential air-conditioning?

The generally accepted range for evaporator airflow in CFMs (cubic feet per minute) per ton of residential air conditioning is between 350 to 450. This range is crucial because it ensures that the air conditioning system operates efficiently and effectively.

When the airflow is within this range, it allows for adequate heat exchange, maintaining optimal temperature and humidity levels within a home. If the CFM is too low, the system may struggle to cool the space properly, leading to higher energy consumption and possible system strain. Conversely, if the airflow is too high, it could lead to insufficient cooling and uneven distribution of air, which can create discomfort in various areas of the home.

This range also aligns with industry standards and best practices, emphasizing the importance of balancing the air handling capacity with the cooling needs of the residence. Understanding this range helps HVAC professionals ensure their systems are properly sized and functioning to maximize comfort and efficiency.
