Mold, The Silent Home Invader

February 10, 2021

Although mold is generally a concern in warmer wet climates it can happen in any home under the right conditions. Mold in most cases causes not only damage to your home and your HVAC system, but it also wreaks havoc on your health Yearly duct cleaning service from Daffy Ducts can limit your risk of mold.

If you can see or smell evidence of mold, you can probably skip having it tested and go straight to remediating it. Look for signs of water or moisture, especially in dark, hidden areas of the home. If there is no evidence and you want to be sure you don’t have mold, you could hire a qualified mold tester to check for mold. However, it’s important to note that the Centers for Disease Control and Prevention states that there are no standards for what an acceptable amount of mold is, as every home contains some level of mold. The CDC recommends asking consultants who do testing to establish criteria for interpreting the results beforehand and share what they will do or recommendations they will make based on the results. 

If you see a dark-colored substance on an air vent that isn’t paint, rust, or something explainable, it is likely a species of mold or mildew. Mold grows on air vents because moisture forms on the metal vents when the HVAC is on, and dust accumulates on the surface — which is a food source. Cleaning the visible mold in vents is strongly recommended because the mold may release spores into the air, possibly causing harmful health issues. 

Mold grows by releasing its spores (reproductive cells) into the air, which are invisible to the naked eye. It can spread and grow anywhere as long as moisture and oxygen are present, but commonly grows on surfaces such as insulation, sheetrock, tile, fabrics and wood. It can enter your home through windows, vents and doorways or it can attach itself to clothing and pets and be carried inside. It might be a shock to learn that you can have hundreds or even thousands of mold spores in one cubic foot of air in your home. 

Mold spores that land on a wet or damp spot and begin growing can produce allergens, irritants and potentially toxic substances. Continuous exposure to a moldy environment can cause or worsen pre-existing health effects. Seemingly healthy people can also suffer from throat irritation, coughing or wheezing, eye irritation or nasal stuffiness in a home with high levels of mold. People who are allergic to mold or who have any pre-existing health issues could get serious infections in their lungs that can spread. Those with asthma could see worsened asthmatic symptoms over time due to exposure to mold spores. Some recent studies even suggest a potential link of early mold exposure to development of asthma in some children.
