Mold in Air Conditioner – Symptoms and How to Prevent Them

Symptoms of Mold in Air Conditioner

If you consistently detect an unpleasant, musty odor indoors with your HVAC system running, it’s a primary sign of mold in your air conditioner. Mold spores can grow in your air conditioning unit, especially when the environment is conducive to mold growth.

When your air conditioner is dirty because the filters aren’t cleaned in a while, it’s likely to increase the humidity and allow the mold to grow. It may be hard to detect them inside your air conditioner, but it’s possible to be on the lookout.

Black Dust

You can identify the mold by its color, which usually appears in black or gray substances. That’s why they are called as black mold or Stachybotrys chartarum. Otherwise, you will find the mold hard to wipe off.

Mold tends to thrive from eating plenty of dust in damp areas of a single surface. The black mold on ceilings or carpets is typically the same in the air conditioner.

Health-related Issues

Other symptoms of mold exposure, indicating the presence of mold in your AC, include persistent coughs, headaches, runny nose, and breathing difficulties. These health issues can arise from inhaling mold spores through air vents.

Especially for asthma, you can be triggered by the mold spreading through the whole room. Some people may also get itchy or irritated eyes, rashes on the skin, throat irritation, and vomiting. Even though the symptoms are likely to be minor, but they can lead to significant health issues, from eye infections to lung bleeding.

Identifying Mold

Identifying mold growth in your home can be challenging. Mold can appear in various colors, including brown, green, white, pink, yellow, or orange, with signs of mold and mildew. When cleaning mold, it’s advisable to wear a face mask to protect yourself from inhaling harmful spores.

Regularly inspecting and cleaning your air conditioning unit and ducts can help prevent mold from establishing an environment for mold within your system.

Maintain the Humidity Levels

You can consider monitoring natural ventilation inside your house to keep the air circulation fresh and healthy. If you have an extra penny, you may want to install air purifiers with the technology to kill mold.

Remember to keep the humidity levels around 30% to 60% for an ideal indoor level. Or else, you can purchase a humidity sensor online to get the simplest yet most effective way to monitor the airflow.
