I've got a question about a new house - a friend of my mother's is buying a new place and when she did a walkthrough (before the drywall was up), she noticed that all the heating registers and returns are near the tops of the walls (on both floors of a 2 story). When quizzed about this the builder (foreman?) claimed it 'worked better this way'.
The registers don't have any directional control (so you can't really aim the heat downwards or anything).
This seems more than a little odd to me - I'd have assumed that you'd want heat registers near the floor with cold air returns at floor level, but some distance away (to give hot air ability to rise, cool to fall). Is this some kind of compromise position for central air? Does it actually work well?
Added: The house is in Maryland, not too far from Baltimore, so both heating and cooling are important. I'm informed also that the house is built over a crawlspace, if that matters.
