I have an average size bedrrom (10' x 12'). It has an 8' ceiling. The temp in this room is running about 3 degrees cooler than the rest of the house. It is heated by a Heat Pump. I know this is not a HUGE difference, but it is noticable and I have an idea that might fix it. Before I give you my idea, let me give you a little more background. The dampers for the this room are fully open. My contracator and I are hesitant to adjust the dampers in the other rooms b/c we are both very happy w/ the temperature consistency in these rooms (all 7 of them). The 'cold room' is the only one on the second floor. The Airhandler is in the basement, compressor outside (of course).
The 'cold room' has a supply duct and a return. I am not sure of the size of them, but tearing them out and putting in new ones seems like overkill and may screw up the other rooms. The are located in the walls (knee high). There is no attic above the rooms. The ducts cannot be moved to the floor b/c there is living area below the floor. Neither one can be raised in the wall b/c the flex ducts actually reside in 'cubby holes' that run parallel to the room and only have 4' high celings.
The supply and the return were placed directly across from each other on the resppective walls (10' across from each other). The grill that was used in the supply blows the air straight out, not sideways. This was done so air would not blow directly at the people in the bed.
My thought is to move the supply laterally on the wall so it is not directly across from the supply, but instead have it diagnolly across the room from the return.
My contractor will do it for me but does not seem to think it will make much (if any) of a difference. Thoughts?
