I have seen this where water has leaked into the ductwork and stagnated.
A sewer smell coming from your sink could be caused by a dried-out P-trap, a clog in the drain, or a problem with the sewer vent.
One of the biggest culprits I have found for sewer gas smell is the floor drain many floor drains are seldom if ever used and if unused long enough the water in the trap will evaporate allowing sewer gas to enter the dwelling. this also applies to any trap which is not used regularly.
Pour water in it. It could be the "p" trap has dryed up allowing sewer gases to come out.
A sewer.
Fleas may come out of the sewer seeking warmth, food, and shelter. Sewers provide a dark and damp environment that is conducive to flea survival and reproduction.

That is condensation and it is normal for water to come out of an air conditioner in the back of it.
