| How much Return air is needed for a 5 ton system with the blower set on 2000cfm .. I currently have a 20x30 return air grill and I don't think that is big enough? |

| you should add at least another return of similar size strategically located in your home. one return even if large enough would not provide good airflow for a 5 ton calling for 2000 CFMs. IMO |

| Maybe I will figure out how to add a flex return duct across the house..Hmm The duct inside the chaise that goes up in to the attic is 27.5" width and 19.5" depth.. |
