It's because when air gets hot it expands, and when it gets cold it contracts. The cold air coming from the air conditioner is denser than the air that's already in the house, so it tends to sink. If the AC vent were in the floor, the air higher up would never get cold, but with the vent in the ceiling, the cold air falls through the room and cools everything. In the same manner, hot air rises, so having the vents in the floor makes the hot air float through the room instead of just staying on the ceiling and leaving the floor cold.

Let's keep it simple; hot air rises, and cold air sinks. Hence, you have the cold air released near the ceiling, and it flows down through the room, and the warm air released near the floor to flow up into the room. It's for a more even dispersement of the 'conditioned' air.

are you able to administration the pass of air on the vents? in case you are able to, close the only in you daughter's room till it really is quite a lot close. this would pressure the nice and comfortable air into the different rooms. you should attempt with all the vents to get the right stability. I even ought to attempt this once a season for aircon in summer season vs. heating in iciness. in case you won't be able to administration the pass on the vents, go purchase new vents at abode Depot which have the administration. replace: i imagine Set decrease than has a level in his answer. it really is fishy that they put in a clean blower without attempting a lot less complicated ideas first. sounds like they don't comprehend what they are doing.

Hot air rises
Cool air falls
Sooooo I guess its to keep the balance

Density and volume????
Jesus, just think, the warm air starts on the floor and warms up.
The cool air starts at the ceiling and cools down.
Hot air balloon.......hint.

Heat rises and cold air sinks , simple as that .
(some contractor used his brains . . . I've seen it backwards !)

Hot air is less dense and rises easily.
Cold air is more dense and decends easily
