Our master bedroom is downstairs. It is in a corner of the house and
the only room having no second floor. This room is much warmer (cooler
in winter) than the rest of the entire home (rest two story). Located
in Houston...HOT!

I have two A/C, furnaces: one for upstairs, one for down. The master
is on the downstairs unit. There are two supply ducts and one return
air in the bedroom.

Here are my thoughts:

1. There is only one duct (medium sized) to the bedroom. It is
apparantly split to the two supply ducts. This is one of the longer
runs on the unit.

2. I am unable to tell if the "small" attic space above this room is
adequately insulated. The builder did not put an attic access in. I
may have to cut the return air plenum to just be able to access the
attic to look.

3. The supply duct to this room is connected to the top of the
plenum...would moving it to a side/end improve air flow? By comparison
with the other vents, the airflow in this room is at least 50% less.

4. I cannot see why a return air back to the A/C is necessary. It is
located in the tray ceiling about 12 feet from the supply vents...could
this simply be pulling the supplied air back to the system (particularly
in winter)??? Would it better to just do a room to room return? The
main return air for this system is located in a very large room and is
very large itself. Why is a return air in the bedroom even needed?
The door is most always open.

I just love these $300k boxes that builders throw together!
Thankfully, the system/plenums are very tight in the attic. The ducts
are well secured with no obvious leaks. Thanks in advance.
