As a homeowner or tenant, one of the most concerning issues you may face is the possibility of mold contamination in your air vents. Unfortunately, the HVAC system is the ideal breeding ground for mold, which requires moisture, darkness, and food to survive and thrive. Check this site if you need help with cleaning your air vent to prevent issues like black molds.
The issue is that different types of molds tend to look the same, so you may not be able to identify them solely by appearance. Although it doesn’t take a genius to figure out where the name “black mold” comes from. It is black, and it can be very dark with a green tinge at times. It isn’t pleasant in either case.
You may not have heard of that term before, but you have probably heard of sick building syndrome. The mycotoxins (or toxic substances) that black mold produces are at the root of this problem. These toxins are responsible for allergic reactions in humans and animals.
When there are molds in your house, you can check for air conditioner signs of black mold in air vents by watching out for the following:
1. Black Dust on the Air Vents:
One of the frequent signs of black mold in air vents include black dust on the vent. If you notice black dust on the surface of an air vent that cannot be easily cleaned, it is most likely a type of mold or mildew, and it is an early sign of the presence of black mold in the air vents.
If mold spores are found in your air duct system, they can be blown to the vents and eventually become black dust.
Mold can also grow on the air vents themselves as dust accumulates on the surface, serving as a food source. Cleaning visible mold on vents is advised because the mold may release spores into the air, potentially causing health problems.
2. Visible Mold inside the Air Handler:
Mold can grow on the surface of air vents and the inside of your central HVAC unit and ductwork. Mold has a darkish or white appearance and is difficult to confuse with anything else. Just be careful not to mistake it with drywall dust every day in new homes.
Whatever system you have, the HVAC air handler is a central location for mold to grow and spread throughout your home.
Mold grows in furnaces and air handlers because they collect a lot of moisture and are frequently dusty (dust is a food source for mold). For Instance, When I was home inspecting, I permanently removed the HVAC cover, and at least one out of every ten homes had mold growth inside the air handler.
3. Musty smell:
Musty smell is a toxic signs of black mold in air vents. If you perceive a musty odor, it’s a sure sign you’re dealing with mold. Likewise, if your HVAC system emits a musty smell when it is turned on, this is a sign of decay in the system.
When you conduct home inspections and discover a mold problem in its early stages (such as in the basement), the first thing you notice is that distinct musty odor — a very ‘earthy’ fragrance.
4. Brain fog:
The presence of black mold in the air vents may cause brain fog. According to a recent study, brain fog is just as common as respiratory tract symptoms. So if you keep noticing this, it is a toxic sign of black mold in air vents that should tell you it is time for proper cleaning.
If you feel weak for no clear reason, it could signify mold in the ductwork. Contaminated air ducts may be causing your fatigue when you turn on the HVAC system.
6. Allergic Symptoms
Allergies such as itchy skin and eye and a stuffy nose are some of the most common symptoms of mold exposure. Mold may also cause a reddish tinge to your skin and eye.
After returning from a vacation, I was exposed to toxic mold.
Mold grew everywhere in the fridge after the refrigerator was turned off. I had an itchy sensation all over my body while cleaning it out and it was not as safe as signing up on piratebay.
7. Upper Respiratory Tract Symptoms:
Mold exposure has also been linked to upper respiratory tract issues in studies. Coughing, wheezing, and even hypersensitivity pneumonitis can occur in vulnerable people. Mold can aggravate asthma and even trigger it in people who already have it.
Types of molds that can be found in your AC air vent
Various kinds of mold can be found growing in HVAC systems, and submitting a sample to a lab for verification will almost certainly be required — but here are some of the most frequent types:
1. Black mold:
Stachybotrys chartarum is a type of mold commonly referred to as black mold. Stachybotrys is rare, and it can only thrive in a specific environment that includes a lot of moisture, little nitrogen, little competition (from other molds), and limited sunlight.
Flooded or homes damaged by water are also known to have black toxic mold (Stachybotrys). In addition, according to recent findings, S. chartarum has been linked to sick building syndrome.
This is one of the frequently found molds (genus) families found indoors, and it can appear in various colors. This mold may be difficult to identify because of the variety of colors and shapes. Yellow, green, and white are the most common colors.
Aspergillus can infect the lungs or sinuses of people who have weakened immune systems (which may spread to other areas of the body).
This is another type of indoor mold that can grow in air ducts. This mold has a leather-like texture and is available in brown, gray, and greenish-black. Ulocladium is frequently found growing with other molds such as Stachybotrys.
Acremonium is a mold genus (a variety of species) that grows slowly (months or years) and has a white powdery appearance. The molds in this family are typically gray, white, or pink. Another characteristic of this mold is that it is compact and moist.
Mucor is a mold genus that contains over 40 different species and is commonly found growing in HVAC systems. It is a kind of mold that grows quickly and usually takes on a white, brownish, or gray color.
Ensuring that your AC is free of these types of mold is important to keep your home safe. It is not enough to only have an Air Conditioner installed, you also need to ensure that you properly maintain it by cleaning the vent and other compartments. This way the system can remain durable and serve you better.
