what would cause a air condition to smell bad even if the a/c is good
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.
