Question the air from the a/c vents started smelling like rotten eggs. any suggestions?
Answer Look carefully at all of the ductwork to ensure there is not a fitting that has separated allowing animals to invade the duct system. If no damage is found, I would turn the unit breaker off and thoroughly clean the indoor coil with a liquid dish detergent such as Joy, and rinse it and see if it eliminates the odors. Thanks J
