This duct is right beside the washer, too, but I don't feel any damp areas of the carpet, so I don't think it's leaking into the nearby duct. I get the feeling that the water might be coming out of the indoor Coleman blower unit (the A/C itself is behind the house), though I'm not 100% sure.
If it helps, here's the info on the Coleman unit that's inside the house:
Model #: DGAE080CDK
Serial #: W0F6557001
Any help appreciated...can't risk losing our A/C during the hottest month of the year!
