Can Duct Cleaning Remove Mold?
Comfort that makes a splash

Mold is a word that strikes fear in the heart of any homeowner. A mold infestation can lead to health issues, cause significant damage to your property, and contribute to unpleasant odors. While it’s nearly impossible to avoid mold entirely—since spores can enter your home on clothing, shoes, and pets—it can also accumulate in areas like your HVAC system, especially in high-humidity environments.
At Big Fish Heating & Cooling, we provide comprehensive duct cleaning services designed to effectively eliminate mold and prevent the numerous issues it can cause. Our expert team not only removes mold but also helps enhance your indoor air quality and optimize your HVAC system’s performance.
Why Your Ductwork Contains Mold
When you think about the conditions where mold thrives — dark, warm, and humid — it’s easy to see why HVAC ductwork creates the perfect environment for it to grow and spread.
You can find mold in HVAC systems for several reasons. Heating and cooling systems naturally create moisture, and when water droplets condense inside the system, it supports growth. Dust on critical components and sludge inside the condensate drain also feed the spores, which blow through the ductwork.
While you might see mold on air vents and grills, the most common signs that you need air duct cleaning for mold are musty and unpleasant odors and an increase in respiratory symptoms. Mold exposure can also cause symptoms like nausea and headaches.
Duct Cleaning To Eliminate Mold
When you discover mold in your HVAC system, duct cleaning can help remove the spores and mold growth. This thorough process typically involves using specialized equipment such as high-powered vacuums, agitation tools, and antimicrobial treatments to ensure that the ducts are effectively cleaned and sanitized. However, unless you address the underlying cause, mold removal in ducts is only the beginning. An unrepaired water leak, excessive humidity, a dirty HVAC unit, or other issues will allow the mold to return.
To prevent mold growth in ducts from returning after cleaning, you have to address the root cause. You also need to keep up with regular HVAC maintenance (including changing the air filter), seal leaks, and consider adding a dehumidifier and air purifier to the system. These tactics can help keep the air ducts clean and dry so mold doesn’t have the opportunity to spread.
Why Professional Duct Cleaning Is Necessary
Duct cleaning is helpful for remediation and mitigation after HVAC repairs. However, it’s critical that you leave mold removal in ductwork to the professionals, as they use advanced cleaning and sanitation tools and techniques.
Attempting to clean the ducts yourself can damage the system, and without the right tools, you could spread the mold spores further into your home. Either way, it’s unlikely that you’ll be able to reach every nook and cranny where the spores can hide in the system, limiting the effectiveness of your efforts.
