Osb board around AC unit looks wet, smells of mildew

I pulled up carpet and vinyl in hallway and noticed that osb board is darker (wet I guess) Smells like mildew. This area is around the AC unit. I assume that the AC pan overflowed at one time before I moved in. There is always about 1/2 inch or less of water in the drainage pan of AC. The Ac was filthy when I bought the house and coils covered with sooty black material which I cleaned. The drain is draining outdoors. Is it possible for me to clear drain out so pan will be dry? Also, will I have to replace the OSB board? I sprayed a little clorox on it. I assume that the board beneath the ac in the closet is also wet. Is it a big chore to remove all of the unit to get to the board for repacement?
