We own a ranch home, 3 bedrooms and bath at one end, living room in the middle, kitchen, then converted garage on the other end. The bedroom end of the house is always cooler than the other side.
The converted garage is now a family room and all the electronics are in that room, tv, computer, stereo, games, etc.; generating heat and causing this room to be as much as 10 degrees warmer than the rest of the house, even in winter. This room sits on a slab that extends out both sides of the house, in front it becomes the driveway. The previous homeowner did not insulate the floor and so this room gets very warm in the summer. It only has one vent that supplies heat and air conditioning.
The kitchen connects to the converted room and is also very warm in the summer. There are no vents in the kitchen but there are two vents in the connected dining room. There is no air return in the kitchen/dining rooms.
Obviously it would be nice to add vents to the converted room, but someone also suggested that adding an air return would actually be more beneficial as it would give the hot air somewhere to go. The room has no air return currently. There are two air returns at each end of the hallway where the bedrooms are that area seems to get the lion's share of heating and cooling from the furnace. I also wondered if just adding a vent near the ceiling that would connect the converted room to the living room would allow enough air exchange that it would even out the temperatures.
Beyond what I stated, I'm lost as to how I can even out the heat/air conditioning in these rooms.
