PM I'm confused and maybe someone can help.  We built a new
house and one end of the house is cooler than the other. The
south end is the hottest. The house is a month old, full brick
and we paid to have "upgraded" insulation(yes, it was
installed).  If you look at how the ducting is done, the duct
from the blower is fed into a box that has many ducts of
different sizes coming out of it and going to each room. This
box is located on the cooler end of the house. The ducts on the
cooler side of the house range from 3 ft(about under the box) to
20 ft. The hotter side of the house has one large duct going
about 25 ft and connect to another box and this feeds 3 rooms.
The other duct on the hottest room in the house is about 1/2 the
size of the other and goes about 20 ft and splits off a small
duct to the entry hall and the continues about another 20 ft to
the duct in the hot room. All the air comes out in the entry
hall so I shut this register and more
