Mold is a common problem in air conditioning systems and air ducts, and it can cause a variety of health issues. Unfortunately, the vents are an ideal environment for many varieties of mold, and the symptoms can consist of dark spots, strong and musty odors, allergic problems, respiratory problems, etc. In this article, we'll discuss the different types of mold in air ducts, their effects on health, and how to maintain a clean and healthy air duct system. One of the most frequent types of mold found in air ducts is accremonium.
This type of mold looks like a white powder and rarely infects humans, but it can cause some health issues if it joins other types of mold. For example, it can cause endocarditis, pneumonia, and subcutaneous infections. Another mold commonly found in air ducts is Alternaria. This type of mold is one of the most common allergens in humans and can cause many symptoms among people who have allergies.
It can also cause asthma. Alternaria is usually greenish or brown in color and has a velvety texture. It usually appears when there is any type of leak or condensation in the air ducts. Poor maintenance, lack of cleaning, and failure to treat leaks and other problems can also contribute to mold growth in air ducts.
Identifying and eliminating mold in air ducts is essential to maintaining a healthy living or working environment. Mold in air ducts is caused by a combination of factors such as high humidity levels, inadequate ventilation, leaks, and the presence of organic materials such as dust, dirt and debris. It's important to note that most homeowners can get away with cleaning their ducts every several years, so this service isn't expensive at all. Professional technicians use specialized equipment and tools to clean supply, entrance and return ducts throughout the house.
You can't always know for sure if you have mold in your air ducts (unless you have a visual test) without first testing for it. When mold grows on ventilation grilles, these spores can travel throughout the house along with the air that circulates. The accumulation of moisture in air ducts due to leaks, condensation, or high humidity is an important factor contributing to mold growth. Aspergillus is a type of mold found in air ducts because of its ability to grow on a variety of building materials.
