Why Air Conditioner Mold is Dangerous

Medical News Today reports that while mold in the home may not always pose a severe threat to life, it can profoundly affect health by emitting toxins that compromise the respiratory system. This exposure can cause allergic reactions, respiratory difficulties, and conditions such as aspergillosis. The danger increases significantly when mold contaminates air conditioners. They can disperse readily through your living space, exposing occupants to detrimental spores. Additionally, mold can harm the air conditioner itself. It can infiltrate electrical components, which may decrease efficiency and lead to costly repairs or even complete replacement.

Signs of Mold in Your Air Conditioner

Pay Attention as to do list written on white board

Considering the health hazards posed by mold, it’s essential to stay alert for signs that your air conditioner might be hosting this undesirable invader. Mold tends to flourish in the moist parts of an air conditioning unit, making it difficult to spot with the naked eye. The challenge is increased because mold spores are microscopic and generally not visible until they accumulate into larger clusters.

It is recommended to seek the expertise of a professional HVAC contractor to reliably detect mold in your AC, its ventilation system, or other areas of your home. An experienced HVAC professional with the required expertise and familiarity with similar cases can identify mold presence. They are trained to do so even when the spores are microscopic and not visible to the naked eye. Considering this, it is crucial to be aware of specific signs that indicate mold growth within your air conditioning system.

Visible Signs Of Air Conditioner Mold In Your Surroundings

While mold may start as microscopic, it becomes easier to spot as it grows and releases spores. Depending on factors such as moisture, light, and nutrients, mold can appear in various colors like brown, white, black, gray, green, red, orange, and purple. These variations help make mold visible. Be vigilant for any unusual color patches or growths, which could be signs of mold presence.

Musty AC Smell

A musty odor is usually the first and most clear indication of mold or mildew. If you encounter an unexplained musty scent in your home, it’s likely originating from mold within your air conditioner.

Increased Home Humidity

A noticeable increase in humidity levels inside your home while the air conditioner is active might suggest mold growth within the unit. Air conditioners are designed to cool the air and reduce humidity. If mold clogs the system’s components, it can disrupt this function, resulting in abnormally high indoor humidity.

Tips to Prevent Air Conditioner Mold

Discovering mold in your air conditioner typically indicates that the issue is advanced, potentially having already caused damage. Thus, prevention is key to avoiding the challenges that come with mold infestations. Regular upkeep by a professional HVAC technician helps keep your air conditioning system mold-free. To protect your unit from mold, a skilled HVAC contractor will carry out several important maintenance tasks:

  • Disinfecting the AC: Disinfecting the air conditioner, ducts, and ventilation components is essential to maintaining a healthy air system by eliminating mold and other microbes. A professional HVAC contractor will utilize EPA-approved disinfectants to perform this critical task.
  • Cleaning & Replacing HVAC Filters: For optimal air quality, clean your AC filter every two weeks or more often in areas with high pollution levels. As the U.S. Department of Energy advises, replacing the filter every 45 to 90 days is essential for maintaining system efficiency. A skilled HVAC contractor can best manage this task to ensure thorough and effective maintenance.
  • Applying a Mold Inhibitor: A mold inhibitor is a specially formulated chemical solution designed to prevent the growth of mold and mildew in your system.
  • Keeping Air Ducts Dry: Moisture in air ducts creates a conducive space for mold and mildew growth. To prevent this, your HVAC contractor will ensure the ducts remain dry by thoroughly cleaning them, addressing necessary repairs, and replacing any water-damaged components.
  • Installing a UV Light: Installing a UV light in your air conditioning system offers a potent preventive measure, as UV light can neutralize almost all types of microbes, effectively helping to prevent mold growth within the unit.


Mold in air conditioners is a severe threat to the structural integrity of your home and the health of everyone inside. To protect your living environment and ensure the well-being of your household, it’s essential to employ a reputable HVAC technician. Arrange appointments for regular inspections and maintenance of your AC system. A certified HVAC professional can also offer expert guidance on effective measures to prevent mold growth. Their expertise can help keep your home safe and healthy.
