I went to an independent shop and they found that it was 1.5 lbs of freon low. They added some with a dye when they were diagnosing the problem. He said I have a leak somewhere and that the A/C will work until the freon is low again. This caused the compressor to not kick in thus, no cold air. I'm supposed to take it back Monday to see where the dye is leaking from.

$1600 is expensive, but it's a whole lot better than $3400
