9 Types Of Mold That Can Be Found In Your Air Ducts


One of the bigger problems that homeowners tend to face when it comes to the overall maintenance of homes is the problem of mold. This substance is not only hard to look at, but can also be incredibly dangerous for anyone living in these spaces. Because of the nature of mold, it can be harder to spot at the beginning and is something that tends to grow over time if not taken care of at the earliest.

Generally, mold is known to grow in damp and dark places, and in areas with lower temperatures as compared to the rest of your home. Mold can occur in any part of your home, or even in your general home appliances if not tended to appropriately.

One of the more common places that serve as a spawning ground for mold is air conditioners, particularly, the vents and ducts that help the airflow to different parts of a home. Because of the nature of air conditioners, it is incredibly easy for mold to grow rapidly, becoming rather hard for the homeowner to deal with themselves. Air conditioners tend to have a high amount of moisture and generally remain damp on a regular basis.

The temperatures inside these are also significantly lower as compared to the rest of the home, providing the ideal temperature for mold to grow and spread.
To be able to properly take care of the problem of mold in your air ducts, it is essential to know the different types of mold that can present themselves, and the look of each of these specific types. The following are some of the more commonly occurring types of mold that are found in air ducts and vents.


1. Acremonium
Acremonium is a toxigenic mold that tends to grow over time, taking on an appearance of a white powdery substance. This is one of the more common types of mold that can grow in damp and wet places or areas with water contact.


2. Alternaria
Alternaria is one of the most commonly found types of mold and appears as a greenish or brownish velvet-like texture. This is one type of mold that can grow in any area that tends to have water running through for a significant amount of time, which is why it is rarer to find these in air ducts and vents.


3. Aspergillus

6. Mucor

7. Stachybotrys

8. Trichoderma
Trichoderma is one kind of mold that can only grow in spaces that are constantly wet or moist, which is why their appearance in air vents is incredibly common. This type of mold looks like spores and can multiply rapidly, thereby leaving a very persistent threat in your home.
