Do you have a finished basement?
No basements in much of Texas -- well, VERY rare. The ground here is not good for basements. It costs a lot of money if you want one.
In a hot climate, like Texas, heating is not as important as air conditioning, so ductwork is above rooms, and vents are in the ceiling (cool air settles). Return vents are in the ceiling, too. We also tend to have high ceilings, so hot air in the summer rises above people level. My lowest ceilings are ten feet -- my highest is 24 feet. Of course, that isn't ideal for cold days, but the hot days FAR outnumber the cold days down here.
If you are wealthy, the ideal setup down here is radiant heating in your floors, and air conditioning in your ceilings.
