Check your furnace fan. The air conditioner unit can be running but the air circulation is usually done with the fan on the furnace. If you have a fan switch on the thermostat, check to see if it is in the auto position. If it has the settings on/auto/off, you can switch it to the on position and see if you get any air movement then. If not, you could have a broken belt.
If dust is coming from your air conditioner, you did not put in a filter. You will ruin your air conditioner running it without a filter. Also, the vents will get dusty. You need to clean them.

Steam may be coming out the air conditioning unit if the engine is overheating. The best thing to do would be to shut the vents before any hazardous fumes begin to come out.
