We are in a townhome that has 3 levels, and the heat/cooling ducts run
in 2 levels (on the ceiling in the bedrooms upstairs, and under the
floor on the living area).
Centex provided a lever in the unit in the basement that allows for
the air flow to be channeled to either of the two or to a mix of the
two (depending on the position of the mechanical lever).
I found that one end of the lever works well (all the air flow is
channeled completely to the bedrooms), but the other end does not shut
it off completely. In my neighbor's home the channeling works well.
To give an example, in Winter, the bedrooms get really hot (while I
would love to shut off the hot air flow to the top floor completely,
and let it in the living area, from which it will eventually reach
upstairs due to the hot air).
Has anyone seen this issue before, and any thoughts?
