Cause of Black Dust Surrounding Your Air Vents

It is well-known that moisture is produced by air conditioners. Moisture produced from the dehumidification of air is eliminated through the unit’s drainage pipe. However, the humidity is also generated from condensation, which doesn’t have anywhere to go. Although there is cold air flowing out of the air conditioning system, the warmer air that is around and inside of the unit can cause small water droplets to form around and inside the air ducts and vent. With this small amount of water is combined with particles of dust, it provides the ideal environment for mold infestation. Therefore, moisture and dust are what causes black dust surrounding your air vents.

The first thing you should do is call a certified inspector who will be able to tell you whether or not that black substance that is clinging around and in your ducts and vents is black old. After that has been confirmed, you either can purchase a mold removal product that has been approved by the EPA or use a DIY suspension. If you plan to handle this situation yourself, suit up and wear industrial-grade gloves, safety goggles, and a mask.
