Having the ceiling fan blow upwards will circulate the heat through the entire room.
On the vents closest to the main unit it should read around the same temperature that the thermostat is set to after its been running and then as the venting increases the temperature should be less, between 2 to 10 degrees different depending on how well the ducting is in the attic........
This could be due to a problem with the ductwork, such as a blockage or leak near the air handler that is allowing warm air to mix with the cold air. It could also be an issue with the damper system not properly regulating airflow to the rest of the vents. Have an HVAC technician inspect and potentially repair the ductwork and damper system to resolve the issue.
Smoke detectors should be placed at least one in every bedroom, outside each sleeping area, and on every level of the home, including the basement. They should be placed on the ceiling or high on the wall, away from windows and vents. Follow the manufacturer's guidelines for specific placement recommendations.
Steel wool can ignite when exposed to high heat, such as from a heating vent, because of its fine and flammable nature. It can catch fire and potentially lead to a hazardous situation. It's important to keep flammable materials away from heating vents to prevent accidents.
Most people set the fan to blow air down regardless of the season. The theory of a ceiling fan is to draw heavier cold air from the ground and circulate up towards the six foot level. In the heat season you are supposed to change the direction of the fan so it now blows down to remove the lighter warm air from the ceiling and push it down to the 6 - 4 foot level. My vents are up high, I want the conditioned air at my level sooner than later. So, if you're like me, you blow the air down all year round, then sure, why not. The air coming from vent my spin the fan a little should the fan be in the off position. No harm there.

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.
Heating vents are typically placed near the floor to ensure better air circulation and distribution of warm air throughout the room. Placing them near the ceiling may lead to stratification of air, where the warm air stays near the ceiling and doesn't effectively heat the room.
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.
should be on floor.
Ceiling vents should be directed towards the room to evenly distribute air throughout the space. Pointing them towards the window would not effectively cool or heat the room.
in the floor.
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.
The inside of the ductwork is dirty and is blowing the dirt out.
It would be better to place the heating vent near the floor because the heat will travel up and down, so that way the room would be heated evenly. If you place it near the ceiling, the heat would not heat the floor that well, since the heating vent sucks back in the heat
Ceiling. Cold air fails
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.
