How to clean AC ducts for child's cough?« Back to Previous Page

Dust buildup in AC vents is a common trigger for respiratory irritation and coughing, especially in children. In Dubai's climate, with year-round AC use and high ambient dust, systems accumulate particulate matter, microbial growth, and allergens that get circulated.

For a thorough cleaning, hire a professional service that uses a truck-mounted HEPA vacuum system and rotary brushes to dislodge and extract debris from the entire duct network. Avoid companies that only offer a basic wipe-down of the visible vent covers—this doesn't address the contamination inside. A proper service should include cleaning the evaporator coil, drain pan, and blower assembly, as these are common sources of moisture and microbial growth. The Dubai Municipality recommends that AC duct cleaning be performed by certified technicians to ensure it meets local standards.

After cleaning, consider requesting an independent post-cleaning surface swab or air quality test to verify the reduction of particulates and biological contaminants. This provides objective evidence the cleaning was effective. For ongoing maintenance, using high-quality air filters (MERV 8 or higher) and changing them every 2-3 months during peak cooling season can significantly reduce dust recirculation.

Since visible dust and a correlation with coughing are present, a professional inspection is advised to assess the full system. In many villas in Jumeirah, older systems or those with undetected moisture issues can harbour mould that isn't visible, which would require specific remediation.
