We bought a house new construction in 2007. The master bedroom has two heat outlets in the floor on one side of the room and the cold air return is in the ceiling on the other side of the room. This cold air return is sized 12" x 12" and right over our bed!! My problem is now that at times cold air seems to be "falling" out of this vent, making it uncomfortable sleeping conditions and causing me to wake up with dry eyes and/or throat. (The system has humidifiers and we do have a hygrometer, it is not too dry in the room.) Unfortunately we cannot move our bed, the bedroom is laid out in such a way that there is only one solution possible, right underneath this vent. I started noticing this draft only in the winter for the obvious reasons and initially it did not bother me as much. However this year it is bad, and I have to pull up the blankets way up in order not to feel it. As I mentioned before it does not seem to be happening all the time. Is this something that can be corrected? Has it maybe to do with the fact that there is a discrepancy in heat distribution between the master bedroom and the three kids bedrooms. The thermostat for the upstairs heat zone is in the master bedroom and with bedroom doors closed the kids rooms heat up far too much, therefore I have to close the heat outlets almost entirely in these rooms.
Any suggestion is appreciated.
