Could musty smell and coughing be due to dirty ducts?« Back to Previous Page

After the rain last month, I noticed a strange musty smell lingering in the hallway near the children’s room. The AC in our apartment has been running more often lately, and my kids have been coughing up a storm especially at night, which is unusual for them. Given these observations, could this be related to issues with duct cleaning? If so, what signs should I look out for that indicate we need professional help?

Could musty smell and coughing be due to dirty ducts?

Yes, it’s highly likely that the musty odour and increased coughing could be linked to issues within your apartment's HVAC system. In Dubai and the UAE, humidity levels can fluctuate significantly, particularly after rain events. This moisture can lead to mold growth in poorly maintained ductwork if adequate ventilation isn't present.

Dirty ducts are a common source of indoor air pollution in buildings like yours. Mold, dust, and other allergens can accumulate over time, especially during the rainy season, contributing to those unpleasant odours and respiratory issues your children have been experiencing.

When mold grows inside your ducts, it not only produces a musty smell but also releases spores into the air that can be inhaled by occupants. This is particularly concerning for kids who might be more sensitive to such allergens. The coughing at night might also indicate that the air quality is worse during cooler evening hours when the AC runs longer.

Signs that you should look out for include:
• A persistent musty smell, especially after rain
• Increased allergy symptoms like sneezing and runny nose
• Persistent coughing, particularly at night or in certain rooms
• Visible mold growth on ductwork or other surfaces

Given your situation, it would be prudent to contact a professional HVAC service provider who can assess the condition of your ducts. In Dubai, companies like Saniservice are well-regarded for their expertise in this area and adhere to local standards and regulations set by the Department of Economic Development (DED) and the Dubai Municipality.

If you decide to go ahead with a professional inspection, ensure that they use EPA-approved methods to clean your ducts. They should also provide a detailed report on any findings and recommendations for ongoing maintenance to prevent such issues in the future. Saniservice can be reached at 800-MOLDS or via email at hello@saniservice.com.

Remember, maintaining good indoor air quality is crucial, especially with children's health being a priority. Regular inspections and timely cleanings could significantly improve your family's well-being.
