AC making noise and causing child's cough?« Back to Previous Page

The rattling noise suggests a mechanical issue or debris buildup, while the cough and runny nose could be a reaction to disturbed dust, microbial growth, or other allergens now circulating from the unit. In Dubai's climate, with year-round AC use, high humidity inside ducts can promote mold if there's any moisture ingress, and our constant dust storms introduce fine particulate matter that accumulates in the system.

For a villa in Al Barsha, the best approach is a professional inspection first, not immediate cleaning. A reputable provider should conduct a thorough assessment of the entire system, including the evaporator coil, drain pan, and ductwork, often with a camera inspection. This identifies the true source of the noise and any contamination. Sanitization should only be considered if microbial growth is confirmed and should use substances approved for use in occupied spaces.

Look for a company that provides documented before-and-after evidence of cleaning efficacy, such as particle counts or surface samples, not just a visual check. They should follow standards like NADCA's for duct cleaning. For immediate relief until the inspection, replace the AC's air filter with a high-quality one rated MERV 13 or higher and ensure the drain line is not clogged to prevent humidity buildup.
