Mold thrives in humid and dark environments. Air ducts are both humid and dark. Unfortunately, since the deeper parts of the ducts are out of sight, mold spores often go unnoticed for many years and even decades. Black mold in air ducts is a serious hazard and requires a professional inspection to detect.
Due to the constant shift in humidity levels in the ducts, HVAC systems are the perfect breeding ground for mold. Humidity levels change as owners switch between the AC and the heater. The AC blows the mold spores into the air where they come to rest in the ducts and have a non-visible environment to incubate and thrive.
As mentioned, the mold is out of sight. You may, however, experience the common respiratory symptoms associated with mold growth. These are coughing, eye redness, throat mucus, headaches, dizziness, and skin inflammation. Even then, most people just often dismiss these as common spring and summer allergens.
The only way to confirm mold presence is via professional inspection that accompanies a routine furnace and air duct cleaning.
If the mold is out in the open, then you can treat the infestation yourself using a DIY mixture of chlorine bleach and water. Unfortunately, since the inner ducts are inaccessible to the homeowner, you’ll need to seek professional treatment. In more severe cases, the growth may also spread to the insulation. You’ll need to replace the material in this instance.
