Why is my bedroom the warmest in the entire house? Even in winter it's too damn hot?

I have the same problem, because I have the room that faces the sun, and it is on the second floor (the temp changes as you walk up the stairs!). During the winter, the best option is to close the air vents and make sure all the other air vents in other rooms are open, and to crack the window just a tiny bit. During the summer ask if you can close the vents in any unused rooms to funnel as much air as you can into your room.

Also, ask your mom if you can get some thick, thick curtains to help with heat coming through the windows. And you might ask your mom if you can get an in-window AC.

You might try getting an ocilating fan and putting a bowl of ice in front of it on the really bad days. Or finding some sort of tall baby gate to put in your door to keep the cats out. (maybe a screen door, or a piece of net hooked in all four corners that you can unhook to get in?)

It would seem that U need a professional home inspector. This could be a dangerous situation. Is your bedroom on the second floor? Could be that the main A/C unit has a bad exhaust pipe that is leaking the exhaust heat into the space between the floors. Do you have a carbon monoxide detector in the house? If so move it onto your room or buy one for your room. We had a situation once where the concrete floor under the middle of the house was very warm. Then the electric bill (all-electric house) doubled to almost $300 we called a pro and he found the bad pipe. Until then we had not noticed that the concrete slab was very warm in the hall. The hot water pipe had broken under the foundation had broken and the water heater was running almost all of the time!

Also, do you leave the computer running a lot? These make a LOT of heat. We have a home office and two computers in it and it has problems in the room that are similar to yours. The cold air from the A/C in summer runs right across the ceiling and back into the system intake in the hall. I added a different kind of outlet for the incoming air that directs the incoming air to left and right but it still stays too hot.

Next I will add a duct/register like the one in the bathroom for the fan. Might even add a fan like a bathroom fan. Add a good air filter to bugs can not get in. This enables hot air to rise up into the attic -- Remember; hot air always rises. If you are handy maybe u could mount the computer up higher on the wall.

If U are handy you might be able to build a box on the outside of your room and mount the computer out in the box. This is very tricky and complex. Probably requires a building permit and a professional contractor.

Planting a tree is also very expensive unless you want to wait more then ten years for the tree to grow! And did we mention a good shade over the window? Going back to a less than ten dollar fix there is a clear plastic film that easily attaches to the outside of windows and forms a stand-off pocket. This was invented to control heat loss through windows in winter and probably wont work very good on solar heat.

So 1, look for any dangerous condition. 2 find the the heat source. 3 Try the cheapest fix first.

Another inexpensive (for me) trick that I did was to double the wooden siding on the outside of the house. I put roofing tar paper on the outside walls and some 3/4 inch thick by 3 and 3/4 studs onto the wooden studs that are already inside of the outside walls of the house. I then added 4' by 8' siding panels to the new studs. This allows the air to rise between the new siding and makes it much cooler (and quieter) inside.

Close your vent in the winter and open it in the summer. Cool requires insulation and how clever you are. Remember that light is heat. Caulk around windows and anything where you feel air coming in. Double layer your window with coverings like the cheap blinds and then drapes. Use the old castle technique...tapestries were not just for decoration...they insulated the walls. One apartment I put those cork tiles on the outside wall. I can only suppose that your room and vents are closest to the a/c-heater. Landscaping makes a difference too. You have to control how the sun hits your house. I have apartments and the sun hits the second floor in the back and those rooms are really hot in the summer. The bathroom has no air vent so you broil in there. They put aluminum foil to stop the sun from coming in but I suggest some of the window coverings that allow some light in and vision out but block most of the light and heat. Got insulation in your walls...ceiling? That's a biggie. The only other thing I can think of is get a small a/c in your room and use it when you need it. They really don't cost much to get a high efficiency one and it will make your life livable, your a/c bill will lower and the rest of your family can stop shivering. If you really like it cold, have the a/c blow at your bed and have the fan set on hurricane speed over your bed. It's great.

Bless your heart, I know that it gets on your last nerve. You have to leave the door shut because of the cats so you are not getting any circulation in that room but what a/c vents and a ceiling fan are provideing. I would get curtains that were darker and lined to help keep out heat from the windows in summer as well as drafts from cold air in the winter. A shade tree would be wonderful but that's a slow grow! Best of luck and try lined curtains.

The same thing happens to me. Try to open the windows whenever possible to let fresh and cool air in, even in the summer. Simple and it works

put a window a/c in your room. problem solved.
