Hot air blowing from a/c-had been working-had recharged

What is your question?

Had the a/c drained and recharged-w/dye put in-two days later, same hot air-am taking back to service in next two days, but would like to be aware of what problems could be; i.e. seal, etc-would a compressor go?-car has been impeccably and religiously maintained and has only 60,000 miles.
