Where does the heat come from for a floor vent?
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. Heat must travel a shorter distance and enters the room more quickly and efficiently.
Can a heater blow through a defroster vent?
Heat wont blow through heater or defroster vents Warm/hot air will only blow through adjustable vents on the front of the dash, will not blow through defrost or floor board vents. However, cold air (from air conditioner) will blow through all vents – including upper dash defrost vent.
Why does heat rise in a floor duct?
Heated air is less dense than cold air. That’s why heat rises. 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.
Why is there no air flow in the upstairs vents?
I have recently seen several newer furnaces installed that appear to be set on a very low speed when the heat or air conditioning is on, when it should be at maximum. In that scenario, there may be a high enough volume of air to provide reasonable flow at the lower levels of the home, but not the upper floor.
Why does heat not blow from vent to floor?
Heat blows from vents but won’t blow from floor when put on floor mode. heat won’t transfer from vent to floor when put on floor heat blows from defrost. You most likely have an air door actuator problem. It’s stuck in the vent position and can’t shift to the floor position.

Do you have to have cold air return ducts in your basement?
It’s one thing to blow warm air into a room, but cooler air needs to be allowed out of the to make room for the warm stuff. Fail to do this and you’ll never have a warm basement. This is why cold air return ducts must also be installed at floor level, ideally on the opposite side of each room from the heating ducts.
