For example, when a 5 ton system is downgraded to a 3 ton because of a newly encapsulated attic with continuous rigid foam under the siding. Now a nominal 2000 cfm capable duct system might present much lower low static pressure when driven by a 1200 cfm air handler.Recommended airflow is typically 400 cfm per ton of AC. A 3 ton AC would therefore need 1200 cfm airflow. With only 423 sq in of return your air velocity through the grille would be just over 400 ft/min, a good number as far as noise is concerned. Air velocity of more than 500 ft/min will be too noisy for a residential system.
