hello all,
i'm putting in a new furnace in my house, and i'm reversing the flow of the old system. previously, the house had one huge supply vent in the center of the floor plan and a cold air return vent on the oustide walls of the living room and the two bedrooms. i want to reverse this system and make the cold air returns the supply and the huge vent in the center of the floor plan the new cold air return. do i need to have a cold air return in every room? the house is small (only 900 square feet), so i'm wondering if the one large vent will be enough for the return. i appreciate any insight.
