A short diagnostic monologue advising that a fishy, wet-insulation odor in home air usually indicates moisture has entered ductwork. The speaker lists likely entry points—kitchen, bathroom, under the house, attic, overflow, or ground intrusion—and recommends checking for something wet in the HVAC runs.

The kitchen is very. The kitchen and bathroom really are two places where water is very easily. Very easily can get into the ductwork. Depending on where that run is coming out of your home at that is a possibility. Something got some moisture either from under the house, in the house, something drained, or water spilled into that system. Something happened to cause this to happen. Anytime you get a wet insulation smell, it's kind of a fishy odor, very distinct, not pleasant. But usually it's wet insulation. Now, that could happen under the house. In the attic. Something could overflow into the run. Something could be coming out from the ground up, but something is wet. Something needs to be checked out. So that is not a good problem to have.
