What is the common recommended air flow for residential cooling applications per ton of cooling?

In residential cooling applications, the commonly recommended air flow is 400 cubic feet per minute (cfm) per ton of cooling. This standard is based on the need to effectively distribute conditioned air throughout the living space while ensuring that the air conditioning system operates efficiently.

At this air flow rate, the system can adequately remove humidity from the indoor air, which is crucial for comfort, especially in humid climates. This air flow allows for a balance between temperature control and humidity management, helping to maintain a pleasant indoor environment. Additionally, using the 400 cfm guideline helps to prevent issues that may arise from inadequate air flow, such as insufficient cooling and potential system overloads.
