How to Remove Mold from Ducts11/28/2015 Back To Blog
What is mold? Why is it dangerous to us? And why is it found in our air ducts? Simply put, mold is a fungus that grows on organic materials – like dust and dirt, mulch and leaves. In order for mold to grow, the environment must be wet and moisture and humidity must be over 60%. Mold contains many spores, which are easily transferred with air and if the environment they find suits them in terms of humidity, they grow further. Although we come in contact with mold spores in most places outdoors, they have toxic effects on our health when we breathe indoor air contaminated by mold spores. That's why there is so much fuss about indoor air quality at homes in relation to ducts. When there is mold in the ducts, the air is contaminated and you can probably imagine how bad it is for your health. Those with immune and respiratory problems are affected first, and the most common symptoms are related to allergies, asthma attacks, difficulty in breathing well etc.
Removing mold from air ducts is necessary
So, it's only natural to ask why mold is found in air ducts in the first place? Lack of air duct cleaning allows the over accumulation of debris. Air transferred from outside is already contaminated at certain levels. With dust building up throughout the years inside the ducts, the right conditions for bacteria to grow are already there. With mold growing with organic material, there is already the base for its growth. If there is also moisture inside the ducts, you can easily connect the dots. Mold spores find the perfect home for them to grow.
By understanding why mold grows in ducts, you can understand what it takes to prevent it. Air duct repair and cleaning are the best preventive measures, but also the immediate remedy once mold is already there. In order for you to prevent mold growth, you must make sure all ducts are properly sealed and insulated, as well as free of debris. If there is already mold in the ducts, you must remove it with hot and soapy water and let the area dry well. You can also use white vinegar mixed with water and it's good to repeat the task if mold is not removed properly.
Though, if you don't address the problem causing mold growth in the first place, you will deal with the same problem again. With air duct maintenance and inspection, you can discover what causes the problem and this is the most important step for never having to deal with mold ever again. Since it's not safe to come in contact with mold, especially if you are sensitive to mildew exposure, take the right precautions including face covers and gloves! If mold is not removed completely or grows again right after you took care of it, consider air duct replacement. One last advice: checking the ducts and the HVAC unit often and keeping them clean will save you from similar future problems.
