It\'s sometimes better to be lucky than smart. -
Most certainly have Return air grilles in a Useable BASEMENT. Install them as LOW to the floor level as possible. In most case, a well designed duct layout will have 50 % of the TOTAL R/A taken from the basement level. (This allows for a warmer and better circulation of air)in this basement area. For every 10 x 4 - (4- or 5" round pipe) supply register that is in the basement, allow approx 30 sq. inches of return (free area)...ie: 6 x 10 grille, for each supply. Try to locate them in OPPOSITE locations to the supply. If you need more info, feel free to ask. Hube
