How To Get Rid of Mold In Air Ducts

How Does Mold Grow Inside Air Ducts?

Mold spores are very common to find both inside and outside your home or building. However, discovering mold growing on your property is never a good sign.

All mold needs to grow is moisture and a food source. Once it has both, mold can start growing inside your home or building at any time, especially in your air ducts.

Mold can grow inside air ducts when dust builds up over time, providing a food source for mold spores.  In this situation, mold spores feed on the organic particles present in the dust like; plant materials, dead skin cells, paper, wood, and fabric materials, facilitating their growth.

Signs You Have Mold In Air Ducts

If you find mold in your air ducts, it’s important to act quickly. Delaying the removal process allows the mold to continue growing and spreading throughout your home. Therefore, if you discover mold, make it a priority to remove it. Below are some signs you’ll notice mold in your air ducts.

Visible Mold Inside HVAC Registered Boxes:

Evidence of mold growth or rust on the HVAC register is a sign. Most times we would look just past the register plate into the register box will often reveal growth in the register box. Sometimes those boxes are insulated so there can be growth embedded in the insulation material.

Musty Smell:

One of the most obvious signs of mold in your air ducts is a musty or moldy odor permeating throughout your home. This smell is often described as earthy or damp and can be particularly strong when the HVAC system is running. If you notice this persistent odor, then it’s probably a good idea to get a mold inspection.

Allergy-like Symptoms and Sickness:

Mold spores released into the air can trigger allergic reactions and respiratory issues in susceptible individuals. If you or your family members are experiencing unexplained allergy symptoms such as sneezing, coughing, wheezing, or itchy eyes, it could be due to mold exposure from your air ducts. Persistent sickness or respiratory infections without an apparent cause should also raise concerns about mold contamination.

Dust in The Air Ducts:

Many homeowners can spend years without looking into their air ducts or AC units, as a result, dust and debris would accumulate within the air ducts. As we learned above, dust can be a major food source for mold growth. Not every dusty air duct has mold, however, the chances of mold growth in your ducts especially in a humid like Houston, Texas is pretty high.

Risks of Having Mold In Your Air Ventilation System

Spread Throughout Home:

One major risk is that mold can spread throughout the home. As your HVAC system moves air around, any mold spores in the ducts can travel with it and come out through vents in every room. This means mold can quickly spread to all areas of your house. If the conditions are right, the spores can land on surfaces and start growing over time.

Potential for Long-term Exposure:

Continuous mold exposure can also aggravate existing health issues, leading to an increased frequency of symptoms such as coughing, wheezing, and difficulty breathing, and may contribute to the development of asthma in susceptible individuals. 

Individuals with asthma or other respiratory issues may find their symptoms worsened by mold exposure. Such conditions include asthma, allergic rhinitis, chronic obstructive pulmonary disease (COPD), bronchitis, pneumonitis, and immune-mediated respiratory disorders, all of which can be significantly impacted by mold spores in the environment.
