Why is one of my upstairs rooms so much hotter than the others?

Question

so i live in a 3 level townhome with central a/c...the basement stays cool even without a/c. The main level stays cool with ac...sometimes even without. The upstairs is noticably warmer...although bearable with air conditioning. I know warm air rises so this progression is no surprise to me. However, I have one room of the three upstairs that is use as my office. It is noticably warmer than the other 2 rooms...almost to an uncomfortable point.

I have some theories. It is a smaller room (10 x 9) and desktop computer is often running in it, which generates heat. Also, it is facing the front of the house, which gets a lot of sun. I have no blinds on the window so the sun heats up the room all day. A large tree provides shade in the back of the house where the other two rooms are.

But the room is still uncomfortably hot at night...

Any ideas of what I could do? I dont want to get a window ac unit bc it would be ugly to have one of those hanging out the front.

Answer 1

Have you been in the attic to see if the a/c duct into that room is broken or torn?  You may be air conditioning the whole attic.  Or, if the duct work is not in the attic, there may be a blockage (torn insulation) in the duct.  In my house, the a/c in the attic was put together with air ducts feeding off in all directions, and the one to a small side room was built so it only had 1/4 of the duct work open to the a/c flow.

Answer 2

Also, if it's the farthest room from the air conditioning unit, it's not getting quite the blast of air that the lower level rooms are getting.
