Add freon and it will probably work fine.

However, most reputable a/c shops will dump all the old stuff (recycle
it, actually), check the oil level in the compressor, evacuate out all
the air and add the exact right amount of freon. They do this because
they have no way of knowing what kind of refrigerant is actually
inside and what it's condition is. Since it's been screwed up for 3
years you really should replace the reciever/ dryer when the sytem is
opened up.

Ok...a/c has not worked properly in 3 years but I never have cared...now
that someone doesn't want her hair messed up, I am exploring what may be
wrong. Heeding the warnings and advice of some who have posted here, I had
a refer fitter friend slap his gauges on it (yes they were 134a). At an
ambient temp (measured from a couple inches in front of the condensor) of
70, we had 66 on the probe stuck in the center vent. The pressures on the
evaporator side ranged from a low of 45psi to a high of 65psi whereupon the
compressor kicked off then on again when it reached the low reading. The
high discharge side ranged from 50psi to 65psi...yes...those were the
correct readings...We both thought that before we went further and tried
evacuated and charged it, that I should check here....The FSM shows that
with a higher evaporator pressure and a low compressor discharge there are
two possibilities; defective compressor or low charge. Should we add
refrigerant, evacuate and add refrigerant, or replace the compressor? Ideas
sure are appreciated and encouraged.

 

you might have a bad expanison valve
