Could mold in chiller unit cause our symptoms?« Back to Previous Page

After the heavy rains we experienced last month, I noticed a musty smell coming from the corner of our living room. It’s especially noticeable when the air conditioning is on. My kids have been complaining of coughing fits lately, and I’m starting to wonder if there might be mold in the chiller unit causing these symptoms. Could this be a problem? What should we do next?

Could mold in chiller unit cause our symptoms?

Yes, it's entirely plausible that mold growing inside your chiller unit could be contributing to the issues you're experiencing. In Dubai and the UAE generally, after heavy rains, it’s not uncommon for moisture-related problems like mold growth to occur, especially in air conditioning systems and chillers.

Chillers, being closed units with a significant amount of water involved in their operation, can serve as an excellent breeding ground for various types of molds. When these molds release spores into the air during normal operation or when the system is on, it could lead to the symptoms you've described - particularly coughing fits among your children.

The musty smell coming from the corner of your living room, especially when the AC is running, is a strong indicator that there may be some form of microbial growth. In Dubai and the UAE, given the climatic conditions, moisture tends to condense more easily in air conditioning systems leading to such smells.

If this scenario sounds familiar, it's imperative to take action promptly. First, you should contact a professional environmental inspection company like ours at 800-MOLDS or email us at hello@saniservice.com for an immediate assessment of the situation.

During our inspection, we will conduct thorough testing both inside and outside your chiller unit, ensuring that all areas are checked for signs of moisture intrusion and mold growth. We'll use advanced equipment such as thermal imaging cameras to pinpoint any hidden moisture issues. Once identified, we’ll provide a detailed report outlining the extent of the problem and recommend remediation steps tailored specifically to Dubai's climate.

It is crucial not only to address the immediate health concerns your children are facing but also to prevent further damage that could affect air quality and comfort in your home. Mold can produce allergens and irritants, exacerbating respiratory issues such as asthma or triggering other allergic reactions.

Remember, prompt action can significantly reduce the risk of long-term health effects and costly repairs down the line. Don’t hesitate to reach out for a professional assessment – your family’s well-being is paramount.
