There are several reasons why black dust coming from air conditioner. Candles made of vegetable oil, paraffin wax, and other similar materials are common sources. I came to know about this when I hired an AC technician, and he informed me about it. He shared additional causes and solutions, which I have mentioned below.
Causes and Solutions of Black Dust from Air Conditioner
Here are a few causes behind black dust coming from an AC and its remedies the professional informed me.
Issue 1: Soot from Candles or Fireplace Logs
The most common reason for accumulation on air conditioner vents in your house is dark-colored dust and soot.
Tiny black soot particles are produced continuously by burning candles or incense sticks. These particles float into the air and eventually cycle through your HVAC system with the other dust particles.
Black dust can be produced by a navy blue carpet or a black fluffy blanket.
Solution: You must make use of a higher-grade and better air conditioning filter.
Issue 2: Buildup of Dirt and Dust within AC
He also said the air conditioner might accumulate dust, dirt, and other debris. This accumulation may eventually become dislodged and blown out of the device, turning into black dust. This was the case in my AC.
Solution: This problem you can avoid with routine air conditioner cleaning and maintenance.
Issue 3: Your AC Vents are Growing Black Mold.
Mold and mildew can grow and spread throughout the room while the air conditioner is operating if it is not adequately vented or if moisture is abundant. Particles of black dust may be released from the air conditioner as a result.
Solution: You must hire an AC technician to clean it.
I hope you found it helpful.
