It turns out that the smells and other problems in new-style washing machines are caused by slimy bacteria, mold, mildew and other fungus growing on the plumbing and drum inside the machine. Bits and pieces of these nasties get transfered to the laundry during the wash cycles.
Dust, mildew and bacteria can make an air conditioner smelly. Foul smells from air conditioners are most often caused by dirt, mold and bacteria that build up within the unit. These odor causing particles can be found on condenser coils, evaporator coils, drain pans and filters. Moisture and heat make the smells even worse, sending odors through your entire ventilation system.
