The fan is not working.
There could be a number of problems. Dirty ducts or heat exchanger. Wrong speed on the fan, or turning the wrong way. Plugged filters or vents.

The condenser outside is supposed to blow out warm air. It releases the heat absorbed from inside the house by the refrigerant, which helps cool down the indoor space. If it is blowing out cool air, there may be an issue with the HVAC system that needs to be addressed.
No the out side fan is for venting heat away fromt he unit.
Central HVAC provides central air conditioning, central heating, and central ventilation packaged in one unit. As such it will heat, ventilate and cool your home.
Try the thermostat, it may have accidentally been reset to a low temperature. Or the furnace (boiler) that supplies the heat may not be working. Or someone may have turned a valve to cut of the supply of heat to that part of the system. Withou tknowing whether you live in an apartment or your own house that's the best that I can suggest.
Blowing air over a hot plate is generally more effective in cooling it down, as it promotes faster heat dissipation. This is because blowing helps to increase air circulation and disperse the heat, whereas sucking air might not cool the plate down as efficiently.
