What is a ceiling diffuser?
A ceiling diffuser is a type of vent cover that is installed over vent openings in the ceiling. Its role is to supply conditioned air into the space. After the air is processed through the heating and cooling system, it is funneled through the ductwork until it reaches the ceiling diffuser.
What is a return vent?
Return vents: What is a return vent? These vents suck the air from each room and send it back to the air conditioning or heating system. Return vents tend to be bigger than supply vents, and you won’t feel any air coming from them. When an HVAC system delivers air to a room, it increases that room’s air pressure.

How do ceiling vents keep house warm?
Close top return vents.
Closing the top vents will make your system draw in air from the bottom vents that are at the low point in the room where cold air settles. (Hint: In the summer months, open the top vents and close the bottom ones to draw out air from a higher point in the room where it’s hotter).

Why do houses in the South have their air vents on the ceiling?

Why do some homes have floor vents?
But why would your vents be on the floor? It’s because a heating and cooling system is more efficient when the vents are closer to the furnace. Floor ventilations are mostly in homes with furnaces located in the basement and are standard where the piping from the furnace travels through the basement or crawlspace.
Why do some houses have vents on the floor?
Floor ducts are effective because they deliver heated air at floor level. The heat then rises and continues to warm the rest of the room. Floor vents are typically used in homes where the furnace is in a basement or the ducts (the piping from the furnace) travel through an underground crawlspace.
