Thought for the day, which can be answered easily by either asking a friend of mine or by doing some very quick research: I wonder when houses switched from having air vents be on the floor to having them be on the ceiling, and why – sure, cool air falls, but heat still rises…, so it makes sense (in a way) to have heat vents on the floor and cool vents on the ceiling, instead of just one location for both.
