We're currently redoing our kitchen in a 1000sq ft., two story
townhouse, and thinking about removing about couple cubic feet of duct.
I'll try to explain it as best I can:
Our air return duct goes straight down from the 2nd level to the
basement, at mostly the same dimensions the entire length. However,
once it gets near the kitchen floor, it increases in depth from about
12" to 18", and continues at that depth until it hits the furnace.
On the opposite side of the wall (living room) is a return vent, and
this is where the dimensions change. The return vent is about 6" wide,
and the ductwork is about 8" wide- no problem there- but at this point
it goes from about that 12" depth to 18". I was wondering if this is
done for any particular reason, because we'd like to remove the extra
depth in the kitchen area to allow for a cabinet. The return would
only be modified for about 2 feet, and the rest of the return would
Is there generally any things to watch out for, or does this seem like
a non issue? Also, I'm fairly handy, so it seems simple enough to take
a saws-all to it, patch it up with the (now detached) sheet metal, and
tape it up. Am I missing something?
