Is the AC condenser in your system blowing cold air?
This is caused by low coolant levels in most instances.

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.

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?
blowing cool air, is the air only in your mouth... warm air comes from your lungs. temperature also varies by how open your mouth is while blowing air out
why does the fan still run on the unit after it cycles is over. but it is blowing hot air not cold
i think that it is determined by the position of the sun. cheers-rhys stannard 10DL
