QUESTION: The compressor seams to be cycling properly, but the air is just slightly cooler the outside temp.  Sometimes I can smell the a/c smell coeuknhming from the vents but only slightly.

ANSWER: Put your hand ont he inlet and outlet pipes to the evaporator.  When the system is not working very well what do they feel like temperature wise.  One is smaller than the other.

QUESTION: ok, will do, what should I be feeling? one hot one cold? etc

Answer
Hi,

 The fat one is the evaporator outlet and the thin one is the liquid inlet.  The thin one should be luke warm and the fat one should be very cold to the touch.  If the compressor is cycling and both lines are the same temperature report back.
