Is mold from AC causing kids' symptoms?« Back to Previous Page

After the heavy rains last month, I noticed a musty smell in my bedroom closet, which gets worse every time it rains. My kids have been complaining of coughing and sneezing, especially in that room. Could this be related to mold growth from our new air conditioning unit? What should we do to check for mold and improve the situation?

Yes, it is quite possible that the musty smell and your kids' symptoms could be due to mold growth related to your AC unit. In Dubai and the UAE, air conditioning units are a primary source of humidity control and temperature regulation, but they can also provide an environment for microbial growth if not properly maintained.

Firstly, it would be prudent to check the filter and the internal components of your AC unit. Accumulated dust and moisture can breed mold spores which then get circulated through the air ducts. Mold is known to cause respiratory issues such as coughing and sneezing, particularly in children who have weaker immune systems.

To investigate further:

1. Inspect the AC's condensate pan for any standing water or signs of mold growth.
2. Examine the evaporator coil closely; if it appears slimy or discolored, this might indicate microbial activity.
3. Check the air filter for any mustiness and replace it if necessary.

If you find any evidence of mold, it is advised to call in professional environmental inspection services like 800-MOLDS (800-66537) or email hello@saniservice.com for a thorough assessment. They can provide expert guidance on the extent of contamination and appropriate remediation steps.

In Dubai, regulations require that AC units be cleaned every six months at minimum to prevent such issues. Ensure your service provider adheres to these standards by asking for a certificate of cleanliness upon completion of their work.

Additionally, consider installing a dehumidifier in the bedroom if the problem persists after cleaning and servicing the AC unit. This can help reduce humidity levels which are favorable conditions for mold growth.

Regular maintenance of HVAC systems is crucial, but it's also essential to keep an eye out for any signs of moisture or mold. Early detection can save significant costs and prevent long-term health impacts on your family.
