Newer window air conditioners have a pool of water in the bottom which is
always there. The fan in the back splashes the water onto the coils and this
helps it cool more efficiently. This standing water can get things growing
in it. I just pour a little bleach in the side of the air conditioner
outside and this kills whatever is growing in the water.
Then the fishy smell goes away. I only need to do this once or twice a year.
