Air Conditioner Smells Like Dirty Socks

The smell is like dirty clothes that have been stored in a bag for too long. The culprit is likely the presence of mold or mildew on evaporator coils, duct or a clogged condenser drain line.

When the AC system removes moisture from the air, it catches water vapor which condenses back to liquid. The liquid should run out of the system leaving it dry. If it doesn’t, it collects somewhere else. Somewhere else is a problem and this is how mold starts growing

All people may develop allergies from poor air quality. However younger, older and those with health issues are more susceptible to serious illness from poor air quality.

 

Dirty Evaporator Coils

 

When warm air comes in contact with the cold coils, condensation happens. The presence of dirt or dust makes the evaporator coils an ideal breeding ground for mold or mildew.

Clean evaporator coils are if there is a layer of dust, mold or mildew buildup, presence of ice, or weak airflow.

Cleaning the evaporator coils involves dismantling parts of the system. Consider hiring the services of an AC repair provider for proper maintenance work.

Clogged Condensate Drain Line

The function of a condensate drain line is to catch and run out the drops of the evaporator coils. A clogged line traps water that leads to mold, bacteria growth, and even water damage.

It takes a simple, easy DIY solution to de-clog your drain and saves your bucks from paying a repair service.
