Molds can be found everywhere, even in the air, both outdoors and indoors. It is easy to spot them on the walls, ceilings, or floors around your home. However, mold can sneak in places that are easy to overlook or do not show visible signs, such as inside air ducts and vents.

From 1996 to 2006, the percentage of Americans saying that air conditioning became a necessity in the United States increased to 19%. With that, homeowners are responsible for checking, regular cleaning, and contacting a professional for maintaining your HVAC system. Thus, preventing health issues, structural damage, and expenses as well.


Why Does Mold Grow in Air Ducts?

Mold spores need moisture and a food source to create mold colonies.

Sometimes, water droplets accumulate in the air ducts and do not evaporate. As a result, moisture forms plus food sources (dust, dirt, or dead skin cells) give mold spores a chance to grow and spread.

Look Out for Signs of Mold in Air Ducts

The following are some signs of mold growth in your air ducts:

1.)Moldy Smell

The first sign you may notice when your air conditioner is running is a strong, musty smell. Mold is usually a damp, stale, or rotten odor in a contained room where your AC is. However, if the mold in air ducts stays longer and is not addressed right away, the fungus will spread throughout your HVAC system and your home.

2.) Health Issues

Mold in air ducts, and air vents can be dangerous since the air will distribute the mold around your home. This can lead to various health effects such as:

  • Asthma-like symptoms

  • Dizziness
  • Fatigue
  • Shortness of breath
  • Hypersensitivity pneumonitis

3.) Appearance of Mold

You can see mold in air vents and around the air ducts and drip pans in different ways.

It may be large and cover a mass area or look like tiny black spots or black mold. Sometimes, it can also appear green, yellow, pink, or blue, or it will just look like a stain or discoloration.
