Auto Air Conditioning & Heater Repair: A/C doesnt blow cold all the time, orifice tubes, vacuum leak

Question
2003 Ford Expedition
I recently took it in to see why it wouldn't blow in front and blow warm in 2nd row. The condensor was icing up and it was replaced, also there was a vacuum leak. problem fixed! then another leak was diagnosed again because it would take 2-3 minutes to blow in front a/c. Now center is cold , front is blowing now and if you accelerate while driving it seems to get cooler, but it doesn't feel like it's cooling enough, kind of humid cool air. What else can be wrong?  they said they did recharge the a/c.

Answer
YOU MAY BE LOSING YOUR COMPRESSOR PUMPING STRENGTH.IF THAT COMPRESSOR BEGINS TO BREAK DOWN IT WILL CONTAMINATE THE ENTIRE SYSTEMS.BOTH ORIFICE TUBES NEED TO BE REPLACED,SYSTEM NEEDS TO BE FLUSHED,ACCUMULATOR REPLACED AND THEN EVCUATE AND RECHARGE A/C.

GOOD LUCK ,DAVIDT
