Either you are out of freon, your compressor is broken or your cabin filter is
plugged. There are other possibilities but these are the most obvious.
it's old and you need to change it.
sounds like your freon may be low
needs heater core replaced wost likely be hind the glove box
Sounds like your cooling system termostate is stuck open.
if its blowing, but not blowing cold its low on coolant. it takes r134a.
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 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.
Replace Thermostat

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?
