Isuzu Repair: Air Condition Not Cold enough, money trust, expansion valve

Question
My A/C isn't low on freon but doesn't blow very cold, a few months ago it was blowing cold but not as cold now, what other problems could there be?

Answer
Well Allen I would have my A/C system professionally flushed, refilled and pressure checked. That includes a new receiver/drier, expansion valve or orifice tube, condensor flush and check and evaporator flush and check. I did this and my A/C system ran like brand new and almost blew snowflakes! It will run you about 125.00-200.00 max and is well worth the money trust me.
