Hello folks! New to these message boards so pardon my ignorance.
Look for some direction regarding interior doors relative to the bottom gaps between the floor and doors needed/required for proper ventilation and circulation for my central heating and AC system return. All 3 BR doorways and 1 BA doorway are in the same hallway. The second BA doorway is located in the master bedroom.
the return air vent/grill is located in that same hallway on a wall (not ceiling mounted) at the very bottom right above the baseboard.
3 BR/2BA home on a slab; brick, hardwood floors(no carpet); 2,200 of living area; right at 3,200 total under roof.
If I need to provide more information, please let me know ASAP.
I live in South Louisiana along interstate 10.
Thanks in advance.
