How to Prevent & Remove Mold in Air Ducts

Nov 28, 2022

Mold is an unwanted intruder inside your home that can reside anywhere it chooses. But, when it opts to take up residence in your HVAC system and air ducts, your and your family's health is at risk. Molds that are present indoors, like mold in air ducts, particularly in your HVAC system's drip pans, coils, and ductwork, can be extremely harmful to your health. Some molds create mycotoxins that are known as "toxic molds," which can cause neurological problems and even death.

This article will provide guidance on the removal of mold from your HVAC air duct before it becomes a danger to your health. However, you must first be aware of how to identify mold in these places.

How to Find Mold in Air Ducts

Mold spores grow in moist, warm environments, so they may develop in your air ducts if the air is excessively wet and there is no ventilation. If moisture is trapped in your walls and causes condensation, this can also lead to mold in air ducts growth.

If you suspect that there may be mold present in your home's air ducts due to spots that resemble dirt or dust or you notice a musty smell, the best way to confirm this is to contact a certified mold inspector, like Midwest Duct Cleaning. We will collect samples from your air ducts and analyze them in a laboratory to determine if mold is indeed present.

How to Eradicate Mold Inside Air Ducts

Consider the following proven steps to eliminate mold in air ducts:

  • Only hire professionals - Hire air duct cleaners who are regulated by the National Air Duct Cleaning Association (NADCA). This ensures that they use EPA-approved products and processes for effective mold removal. Do not use steam cleaning or any other methods involving moisture on any kind of ductwork. Attempting to clean your own air ducts can be dangerous without past experience or knowledge.
  • Turn off your HVAC unit - If you think there might be mold present, prevent the mold from traveling around your house.
  • Know your ductwork - You will need to know what type of ductwork you have to get the best possible cleaning. If your ducts are made of fiberglass or have a fiberglass lining, they can't be cleaned effectively and will need to be replaced. However, if your ducts are made of bare sheet metal, it is much easier to remove mold and debris.


To get rid of mold for good, always hire professionals who will use the right tools and cleaners to effectively and safely remove mold. This way their team can also help prevent mold from coming back in the future.


Preventing Mold in Your Air Ducts

Once the mold is removed, find out what caused it to grow and take steps to eliminate the causes. To prevent mold growth in your HVAC system, follow these guidelines:

  • If your home is prone to high humidity, use a dehumidifier to help control the humidity levels.
  • Check for leaks in your walls that could turn into moldy, moisture-damaged problems down the road.
  • Ensure the AC drain pan slopes towards the drain to help remove any pooled water that has gathered beneath the cooling coils. This will also make it easier to access HVAC components and drain pan for cleaning and maintenance.
  • Get a preventative maintenance plan for your HVAC system to keep it healthy and avoid mold growth. This plan will involve regular checkups and cleaning to make sure everything is in working order and to prevent any water damage.
  • Make sure to get your air ducts cleaned regularly, especially if you live in a humid environment or have recurrent mold issues. This will help ensure that your home is free of harmful contaminants.
  • If you are looking to eliminate mold, viruses, and germs from your home, consider installing UV light and ionization air purifiers. These purifiers can effectively remove particles from surfaces and also destroy airborne contaminants. This will create a healthier environment for you and your family.
  • Make sure your air vents are clear of any obstructions to prevent condensation and mold. In rooms with high humidity, like bathrooms and kitchens, make sure to ventilate properly.
