The air duct is 6" x 12". Installed in 1957. The floor just above it seems
to have a soft spot, which is in the subfloor. There may have been an access
point there during a major renovation several years ago.
Regardless, the soft spot needs to be addressed. Unfortunately, it is right
above the airduct.
My concern is that I may need an area of access that is larger than the
duct, so an access panel will not work. In Northern Virginia.
