Could AC mold cause my daughter's cough?« Back to Previous Page

After the rain last month, I noticed a musty smell coming from the air conditioning unit in my bedroom. My daughter has had a persistent cough for the past couple of weeks, and it seems to get worse every night when we turn on the AC. Could this be related to the filter not being replaced recently?

Yes, AC mold could potentially be causing your daughter's persistent cough. In the UAE and particularly in Dubai, high humidity levels can encourage mold growth within HVAC systems, especially after rain events like what happened last month. Mold spores can easily spread through air conditioning ducts and into living spaces when the unit runs, which might explain why her symptoms worsen at night.

Mold exposure can trigger allergic reactions or respiratory issues in sensitive individuals, such as children. The musty smell you noticed is a strong indicator of mold growth within your AC unit. It’s important to address this issue promptly for several reasons: not only could it exacerbate your daughter's cough but also pose health risks to the rest of the household.

I recommend scheduling an inspection with a professional HVAC service provider who can assess and clean your system thoroughly, ensuring that any mold is removed and that proper maintenance practices are followed. In Dubai, companies like Saniservice offer reliable services for such issues; their contact details are: 800-MOLDS or 800-66537 or email hello@saniservice.com.

Additionally, consider replacing your AC filter more frequently than the recommended six months—especially in high-humidity conditions. Filters should be changed every three to four months and inspected for any signs of mold or damage during these intervals. Regular maintenance and timely replacement can significantly reduce the chances of mold growth and improve air quality in your home.

Remember, keeping humidity levels low through dehumidifiers or proper ventilation can also help prevent future issues with mold growth. Always ensure that when you replace filters or clean ducts, you use products that are safe for indoor environments to avoid introducing additional irritants into the air.

Taking these steps should help alleviate your daughter's cough and improve overall air quality in your home.
