What Causes Mold To Grow In My Hvac System

Mold grows in dark and moist areas which is why youll often see first signs in places like your bathroom, especially if you do not have very good ventilation.

Other common areas for mold include attics, basements, and in cabinets with sinks.

Of course, one of the most common places where mold grows is in your HVAC system.

This is because there is a high level of moisture and condensation. These two factors come into play most commonly during the summer months of the year.

When you use the air conditioning during the summer months, water vapor can make its way inside the air ducts. If the area where you live is very humid, the water will stay stuck in your system instead of evaporating like it normally would.

As external particles continue to travel through your air ducts, dust gathers, thus becoming a feeding ground for mold. Mold feeds off organic materials, allowing it multiply at an exponential rate.

Preventing Mold Growth In Ductwork

Now that youve cleaned off the active growth, you need to take action in preventing new colonies of mold. After cleaning, you can use an EPA registered disinfectant fogger to kill spores that may have escaped. You can also apply a mildew inhibitor to your entire HVAC system. Be sure to select a product that is specifically formatted for heating and cooling units and is registered with the EPA. This will limit the risk of applying an ineffective and toxic chemical solution to your unit and the air inside your home. If you dont take steps to prevent growth, you can have another mold problem within just a few weeks in the same area.

Proactive Measures Are Better Than Reactive Measures

Its always better to stop a problem before it starts. Because mold can be harmful to your health, or others who enter your home, this is especially true. If you are cleaning the mold yourself, use of an inhibiter once the vents are clean will help prevent mold from reappearing.

Because moisture breeds mold, dealing with humidity is another proactive step to take.

A dehumidifier is especially helpful when you live in a humid region. Be mindful that an AC system reduces humidity by nature, and using a dehumidifier may only be needed during times when the AC is not in use.

Concluding Thoughts

Mold is scary, but you can handle it yourself. Just remember to make sure to protect yourself when cleaning. If mold is growing on your vents, there is cause to check other parts of the HVAC system.

Drip pans drain and any other parts of the system where moisture is present is where mold will grow. Again, theres no need to panic just apply a few simple cleaning methods.

What Causes Black Mold In Air Vents And Ducts

Mold in air ducts most commonly occurs when there is moisture inside the ductwork. As cool air flows through the vents on hot days, the moisture in the air can condense inside the air vent. You can see the same principle at work when you drink an icy beverage, and water beads up on the outside of the glass. When moisture is present, mold can flourish inside vents. The mildew can be introduced into the vents in several ways.

Mold spores are generally air borne, or spread through air. Spores can enter the duct work by simply blowing in from another area of the home, or from outside. The conditions need to be right for the spores to develop, however. A single mould spore can blow inside your home and begin to develop into a colony if the conditions are right. Warmer, moist environments are ideal for mildew spores to grow.

Realizing The Cause Of Mold In Air Conditioning

While mold can grow anywhere, air conditioning ductwork provides a nice warm, dark location for growth. Mold requires oxygen and moisture, and it feeds on organic matter and debris. Ductwork has all of these components. Water vapor is created when cold air with a high moisture content passes through warmer ductwork passages. Rather than evaporating and dissipating outside, the vapor collects into water droplets that coat the interior of the duct system. This becomes the perfect place for mold to root. The dust, pollen, dead skin, cells, and pet dander flowing through the air provide an endless nutrition source for the growth.

Is it unusual to smell mold in the forced air HVAC room of a condo unit ...

Mold spores are a natural occurrence that can never be fully removed from the environment, but when it builds up to visible mold, it is a problem. Mold can thrive in your air ducts if you have a humid, sultry climate with the appropriate conditions. Mold spores thrive in an environment that is warm and moist, such as an air duct. Mold may develop in your air ducts if you have an excessively wet atmosphere with no ventilation or any space that traps moisture in your walls and causes condensation.

Mold testing can help determine if you have mold in air ducts, but the fungus also gives off a distinct musty odor as mold grows. When your heating or air conditioning is on, you may notice the smell, and it will usually be strongest near the mold development vent. As a result, the scent may not be noticeable throughout the entire house but can still be detected in one particular room. On the other hand, the stench might very well continue to linger in adjacent areas and elsewhere throughout the structure.

Mold in air ducts that goes unaddressed for an extended period will absolutely spread throughout the rest of the HVAC systems. Eventually, you may detect the musty odor in every nook and cranny of your house.
