The first reason the air conditioner smells is due to moisture buildup on the heat exchanger of the indoor air conditioner, the moisture causes bacteria and mold to grow on the heat exchanger, resulting in an unpleasant odor.

An air conditioner can also smell when stagnant water forms in the condensate drain. Together with debris, it remains in the condensate drain, and the odor is carried to the air conditioner, which spreads the smell around the room. Both defects can be corrected with regular maintenance, which the Chula Vista Appliance Repair Team recommends every year. To ensure proper drainage of the condensate line, we pay attention to proper design when installing the air conditioner.

Air conditioners can also smell due to improper connection of the condensate drain line to the drain line. If the condensate drain is connected by a non-specialist, the odor from the waste can pass through the condensate line, enter the indoor unit of the air conditioner and the odor is blown into the room.

It is important to remember that the air conditioner draws air from the room into the indoor unit, and with it any contaminants. Especially in heating mode, viruses and bacteria are absorbed into the air. Then they settle on the evaporator of the indoor unit. And as the unit heats up, its humidity is reflected in the outdoor unit. So nothing automatically flushes out those bacteria and dirt. When you switch to cooling mode later in the summer, these contaminants combine with the freshly formed condensate, and the air conditioner starts to smell. That’s why the experts at Chula Vista Appliance Repair Company recommend post-winter maintenance for all of their units, especially those that heat.
