why would 1 room in our house always be hottor or colder than rest?

    We moved into a 1979 house back in March.  Since then, I've noticed
that our daughter's room always seems to be hotter than the rest in the
summer, and cooler than the rest in Fall/Winter.

   Anyone have any suggestions for what might cause this?  I thought it
might be an issue with the ducts, until I realized this was also the
case when we didn't even have the AC or furnace on.

   The strange thing is, this room seems to have more extreme temps than
our son's bedroom - which is on the corner, and thus has about 70% more
exterior wall.  It kind of defies logic, at least at first glance.

Have you actually checked that with a decent thermometer ?

There are some things that make a room appear to be hotter
or cooler when in fact it isnt actually hotter or cooler at all.


One obvious possibility is that it may not be as well insulated as
the other rooms you are comparing it with. That may not necessarily
be deliberate insulation, just the wall construction or exposure etc.


You can get that effect if the walls of his room are better insulated etc.

 

As others have mentioned;
look for poor or damaged insolation. There could be moisture
in the walls that has compromised the insilation, for instance.
Or amybe the builder ran out of insilation before he could finish
the room.

From personal experience I can tell you that insilation makes a big
difference. I had a room like you describe. When I went into the
attic I found gaps in the insilation and one entire rafter bay
was uninsulated. 2 rolls of fiberglass made a huge difference.

You should also check for proper air flow from your furnace.
I would check for broken, disconnected, or crushed ducts.
also uninsulated ducts running through attics or crawl space.
It may also be that the ductwork is undersized.  If the main
duct is too small, it may not have any air left for the
room at the end of the run.

Also make sure that the room has a proper air return path.
If the door to the room is closed all the time, the HVAC
system can't remove the old air.

 

ghosts can cause a room to feel inexplicably cold.
