Mould can be found in all places. It is always a good idea to have your duct air cleaned out every year or two to prevent any damage to your health. If you have been looking for a way to deal with duct air mould, then you’ve come to the right place. Here are some of the most important facts and signs that indicate that there is mould in your air ducts:

What is Mould?

What is the first thing that comes to mind when you think of mould in the duct air? You are correct if you think of a scary-looking fungus growing on your walls and surfaces. Mould is a fungus that grows in damp, dark places and can quickly grow into huge colonies if left untreated.

Although it can be unsightly, mould does not pose any health risks unless you have an allergy or respiratory problems such as asthma or lung disease; however, it can cause skin irritations and allergic reactions such as sneezing or coughing when exposed to high levels of spores.

Indoor mould can be hazardous. In actuality, some varieties of mould can make people ill. Sadly, mould frequently develops in areas that are hidden from view, like the ductwork in a house.

The ability to hire a professional air duct cleaner to inspect and clean the ducts, which removes any potential mould, is provided by being aware of the symptoms of mould in your ducts.

Symptoms of Mould in Your Air Ducts

1. An Overpowering Musty or Mildewy Smell

When your air conditioner or heater kicks on, you might detect a strong, musty or mildew-like odour if mould is present in your home. The smell is frequently more pungent close to the vent where the mould is developing.

2. Mould Symptoms Near The Vents

Mould growth around the vents is the second indication that mould may be in your duct air. The air moving through your ducts may dislodge mould spores and push them around your vents if there is mould present. Mould may be present if you notice any black, green, brown, or yellow growth near your vents. Mould rarely starts to grow on vents for any other reason, so it was probably forced there from your ductwork.

3. Undiagnosed Illnesses

Do you have family members that have mysterious illnesses? Certain moulds can cause rashes, headaches, nausea, fatigue, and symptoms resembling allergies and asthma attacks. The symptoms will probably get worse during the times of the year when your heating and cooling system is operating more frequently if the mould is coming from your ducts.

Therefore, the problem with trying to remove the mould yourself is that you can’t see all of it. The parts you can see are just a fraction of what might be growing in your ducts. When you hire a professional, they will know where to look for hidden areas of mould and how best to extract them without causing any damage to your home or health.

How to Prevent Future Mould Problems in Air ducts

If you have a mould problem, getting rid of it as quickly as possible is important. But what if you don’t have a mould problem yet? Shouldn’t you be taking precautions so that one doesn’t develop in the future? The answer is yes! Duct cleaning should be done at least once every three years.
