Do You Have “Dirty Sock Syndrome?”

“Dirty sock syndrome” is the nasty, moldy smelling odor that can come from your air conditioner when you first turn it on. It is caused by mold and bacteria build-up on your evaporator coil. Mold and mildew can often grow due to the moisture that builds up on the coil after continual use. It is fueled by the dust that collects inside your air conditioner from a lack of filtration and is commonly noticed when a unit goes from a period of heating to cooling. If you’ve noticed a foul smell from your AC recently, trust that it’s time for AC repair in Williamsburg, VA.

In springtime, it is not uncommon for the heat to be on in the night and morning, only to move to a period of cooling in the heat of the day. The heat mixes with dust and moisture in the darkness of your AC unit and makes the perfect environment to incubate dirty sock syndrome. This is a big reason why it is important to prevent mold and provide adequate filtration for the airflow entering your air conditioner. It will help you avoid dirty sock syndrome as well as the need for AC repair.
