It could be that the temp. control cable has become disconnected from the flap that diverts the air flow from the evaporator to the heater core.(which is most likely the problem) Or the flap itself has stuck/broken. Or maybe the A/C system has become stopped-up at some point. Maybe at the orifice tube(the screen may have blown out or cracked). Check the pressure on the low side AND the high side. If the pressure is excessively high on the high side it will probably be the orifice tube clogged up. But I would ckeck that the temp. control cable and flap is operating correctly. Disconnect it from the control assembly and operate it by hand, you can tell if the flap is opening and closing much easier.
The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.
You are out of refrigerant.
no
There is 36.7 IRA that is in a one ton of air compressor.
A southwest wind is coming from the southwest.
How do you know it is charged properly? If you did not put gauges on the system? If no air is coming thru the vents the coil may be clogged. This list could take a long time!!
The reference point is FROM that direction AND that is the way it is blowing.
If the compressor is not coming on at all it could be that you are low of refrigerant and just need to add some more.
pluged filter, dirty coils,
coming from the east.
Check your coolant level.
It regulates the air pressure coming out of the compressor. Usually, they are adjustable and used to lower the air pressure.
