SOURCE: air conditioning is blowing hot air, system fully charged compressor is woring

The problem is the venting door. There are vent doors that are used to switch between AC and heat. Some vehicles use a cable that opens and closes the vent doors, other cars use vacuum and some are electric.

Whatever the case may be, if you feel the cold on the tubes, then the AC is likely working, you have to get the vent door working

SOURCE: my air conditioning blows hot air only, nothing

ok if unit is split system two piece check to see if out door unit is running fan and compressor the air coming out of the fan should be about 20 deg warmer than out door temp if not compressor not running check the capicitor to see if swelled up on top if so bad if unit has electric heat strip a heat relay may be stuck and you are running aug heat to check this pull disconect on out door unit and see if heat is out of vents if heat pump reversing valve may be bad hope this helps

Your coils could be dirty. Also try cleaning the air filter. I am not familar with your exact model but there will be a filter behind the plastic grill. Most of them pull out from the top or bottom of the case. As for the coils get a can of A/C coil cleaner from your local hardware store and follow the directions. Most of the time these two things will get your unit working again.

In almost every case, it is most likely low on freon. Most all systems use some type of pressure switch to prevent the unit from freezing up via a low pressure switch. It also acts as a "Loss of Charge" safety. I would think there is a leak. Most of the time it is in the condenser, evap, or compressor. Usually not real cheap to fix but you got to check it out to be sure.
