Any tips for getting certain rooms to cool better Upstairs room and TX heat!

So our upstairs has 3 bedrooms and semi J&J bathroom. The bedroom that is connected to the bathroom and the bathroom cool well while the two other bedrooms do not at all. The issue is the room that cools is the guest and the other two are the children's room. Does anyone have advice on how two help get the other rooms to cool. Unless the internet is wrong, using the vents to adjust main airflow is a no go and detrimental to the system. I need the kids room to cool not the guest and bathroom.

TIA

Do you have dampers closed on the other two rooms by chance?

Maybe one of those little swamp coolers with ice in the water. It might help a little

Have you had the ducts inspected? They may have gotten pinched or ripped at some point, so you're cooling your attic instead of those rooms.

Do you have an old system? I had similar problems in my second floor until the old system shat out and I had to replace it. With the new system, all rooms cool just fine.

Why? I've been closing the upstair vents in the winter and the downstairs vents in the summer for 20 years - I've never had any problems and it seems to work.

Are you talking about the dampeners in the plenum or the vents in the ceiling?

Just googling it most of what I have seen says closing off vents to push additional airflow and cooling to another room doesn't work and just overpressure of the system.

Could be both. Do you have flex or hard pipe?

What is the aspect of the kid's rooms? Are they getting more sun? How many windows? Size of rooms? Number of vents? Exterior build material?

Along with the other potential system issues, there are a lot of reasons why a room won't cool. My son's room becomes blazing hot when we run the heat, so that vent is closed completely in winter. No issues yet.

You should probably ask your husband

Assuming you have tight windows, a well insulated and well ventilated attic, and well insulated walls a small minisplit is really the only answer I have.

I have this problem in South Bend, Indiana as well. two story house, top story is typically 5-7 degrees hotter than the main level. I spent probably 10k on new windows, 3k on attic and wall insulation, and another 1k on improving attic ventilation (idiots cut ridge vents in the sheathing and then shingled over the cuts before installing the vent).

All of that made just a 2-3 degree difference. Adding a small minisplit system for the three upstairs bedrooms was the only way I could get the upstairs to match the 68 degres of the downstairs on a 95 degree day.
