I know heat rises, but our 1st story floorplan house gets pretty darn warm during the winter months. Other than turning on the AC or opening windows in the upper story zone, anything else that could be done? The majority of the square footage is downstairs and there is only one small stairway leading upstairs.
Forced air heat, supplies overhead. Upstairs is a separate zone. Displacement of sqftage is about 600 upstairs, 1800 downstairs. There are 2 zones, upstairs and downstairs. The downstairs is set to 70 in mornings, but gets up to 75 degrees upstairs without running heat up there. For the upstairs, there is one return air vent in the main rec room. Downstairs there are two in the hallway and master bedroom.
