Is AC causing my child's cough and stuffy nose?« Back to Previous Page

Based on your location in Jumeirah and the symptoms described, it is highly probable that your AC system is a significant contributing factor. The constant runtime you mention is a major red flag; it suggests the unit is struggling to maintain temperature, likely due to issues that directly impact air quality.

The primary difference between a summer cold and IAQ-related symptoms is persistence and context. A viral cold typically runs its course in 7-10 days. Symptoms from poor IAQ, however, are chronic and often worsen when the individual is in the specific environment and improve when they leave it. A dry cough and stuffy nose are classic indicators of two common AC problems in the UAE:

1. Low Humidity: Over-cooling or poorly calibrated ACs can strip all moisture from the air, drying out mucous membranes and causing irritation.
2. Biological Contaminants: A constantly running, potentially undersized AC unit may not be effectively removing humidity, allowing mold and mildew to proliferate in the ductwork or drip pans. This bioaerosol is then circulated, causing allergic and respiratory irritation.

The construction dust is also a factor, as fine particulate matter can be drawn into the AC system. Dubai Municipality regulations (such as the Green Building Regulations) emphasize proper ventilation and filtration, but older villas may not be compliant.

For your child's health, I strongly recommend a professional IAQ inspection. We would test for relative humidity, particulate matter (PM2.5/PM10), and perform microbial air sampling to identify any mold spore contamination. This is not a DIY situation; it requires certified equipment.
