Whether it's winter or summer, hot or cold outside, my bedroom is always the hottest in the house. I have taken temperature readings and the air temperature can exceed 85 degrees. I have a fan almost always running. I open my vent when the AC is running and close it when the heater is running. No matter what I do, my room is always 80+ degrees.

What can I do to make my room a comfortable temperature? The door is sometimes open, sometimes closed. I have an air intake directly outside my room.

  • How is house heated/cooled? If using ducts, can tune the ducts so less heat more cool goes to the room. Blocking sunlight coming though window/s can help cool the room. Where is the room in house, single floor house or multi floor house? Upper rooms tend to be warmer, heat rises.

  • My room is on the top floor of a 3 story house (but really more like 2 1/2 floor, as the basement is partly underground). The house is heated and cooled by a central air handler in the basement with two dampers for the basement and for the top two floors. I'm not entirely sure, but I think it's a 5 ton system. The room is on an outside corner.

  • 1
    Ducts in floor of middle floor serve the middle and basement. Two vertical air shafts - one for supply, the other for return. Large horizontal duct coming off of it into the basement ceiling / middle floor floor, and the shaft continues upward where it branches off in the attic to serve rooms from above. Return air goes into an intake on each floor (in-wall on basement and middle, in-ceiling on top floor) and one in the master bedroom (directly connected to the return shaft, loud.)
