There are a few reasons why a central air unit is not blowing cold air. The coils may be dirty, the unit may need freon, or the thermostat could be broken.

The electric heating elements are probably turned on.
low on freon
if its blowing, but not blowing cold its low on coolant. it takes r134a.
The compressor is so hot b/c there are fans inside that push the hot air out of the refrigerator. No cold air is blowing out b/c the cold air is going into the fridge.

there are a few things to check for. your filters and coils to see if they are dirty. check your pressures to see if you are low on refrigerant. and also your blower motor.

What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?
It could be that the unit is overcharged and the compressor is shutting down on overload. Check to see if the compressor is running when the hot air starts blowing.
