could be that your vent on your dash is open.it will pull outside air in and if you are using the ac the air coming in the vent is from the hot weather outside.........there is a little spinning knob between the vents , make sure it is closed
on the floor on the floor
Heating vents should be located near the floor since hot air rises. If the heating vents are located near the ceiling the heat would stay there and not warm the room.
My ac blows only in the defroster and not any of the other vents i have 98 ford windstar 3.8 v6
Heating vents should be placed near or on the floor in a room because heat travels up not down.
Having the ceiling fan blow upwards will circulate the heat through the entire room.
When you say "exhaust vents in your ceiling" I assume you are referriong to the heating and AC vents inside your house and not the roof vent on the outside used to vent the attic. It is most likely that the duct work was ran in the ceiling for ease of installtion or the house may be built on a slab and they did not want to run the duct work through the slab.
Heating vents should be placed on or near the floor because heat rises. In rising, it will warm the air of the room. If the heating vent were near the ceiling, the room would stay chilly, even though heat was being poured into it.
There may be several reasons why the air only blows out the front vents and not on the floor or the defrost on the 2003 Dodge Ram. The fuses may be blown, or the heating coil is not working correctly.
Thanks for answering the question Should ceiling vents be directed towards the window or the room? NOT
Near the floor. This allows natural convection currents to mix the warm air as it rises to the ceiling.
It's the blend door on the HVAC box. It's what controls what temp air comes through the vents.
Heat rises. So, in areas with long winters, the vents typically are in the floor. But it depends on the construction of the house, where the heating unit is installed and what type it is, etc. So, no easy answer. Ceiling fans are helpful in keeping air circulating, moving warmer air from the top of the room downward which helps even out the temps from floor to ceiling.
