Is my toddlers' cough from dusty AC or asthma?« Back to Previous Page

Based on your description, this is a classic presentation we see in older Deira buildings and it absolutely warrants professional attention. The combination of a persistent dry cough that worsens in the evening in a specific room, coupled with visible dust from the AC vents, points strongly to an indoor air quality (IAQ) issue, not just the generic "Dubai cough."

The dusty air from the vents indicates your AC system itself is likely a primary contamination source. Even with new filters, if the internal ductwork has never been professionally cleaned, it accumulates layers of fine particulate matter, microbial spores, and other allergens that get aerosolized and blown directly into your living space. Toddlers are especially vulnerable due to their higher respiratory rates and developing immune systems. While asthma is a possibility that only a pediatrician can diagnose, the environmental trigger is very likely exacerbating it.

In the UAE, the Dubai Municipality has clear guidelines (specifically the Public Health & Safety Department) on hygienization and maintenance of AC systems to prevent such issues. A standard filter change is not sufficient; a full system inspection and duct cleaning are often required.

My strong recommendation is to get a professional IAQ inspection. We would typically test for particulate matter (PM2.5/PM10), microbial contaminants (mold/bacteria), and VOCs. This will identify the exact irritants affecting your children. Please call our team at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an assessment. Addressing the root cause in your AC system is crucial for your family's health.
