How to clean and sanitize AC ducts in Dubai?« Back to Previous Page

As a certified HVAC hygienist operating in Dubai, the professional cleaning and sanitization of AC ducts is a meticulous, multi-step process we follow, especially crucial in older Deira buildings where microbial growth is common due to high humidity and aged systems.

First, a comprehensive visual inspection is conducted using specialized borescope cameras to assess the level of contamination inside the ductwork and the evaporator coil. This is non-negotiable under Dubai Municipality guidelines, as it dictates the remediation protocol. We then set up critical barriers and use negative air machines with HEPA filtration to contain the work area and prevent cross-contamination into your living space—this is vital for your kids' health.

The actual cleaning involves powerful truck-mounted HEPA vacuum collection units to extract all loose debris, followed by aggressive agitation of the ducts with rotary brushes and air whips to dislodge stubborn particulate and microbial growth. The evaporator coil and drain pan, often the primary source of issues and that "unfresh" smell, are meticulously cleaned and treated with an EPA-approved, non-toxic antimicrobial sanitizing agent to inhibit future mold and bacterial growth. Finally, we perform a post-remediation verification (PRV) to ensure the indoor air quality meets the standards set by the UAE's National Air Quality Strategy.

Given the symptoms you describe—non-stop coughing and visible black dust—this is a serious case requiring immediate professional attention. DIY attempts can aerosolize contaminants and worsen the problem. For a certified assessment and remediation, please call our specialists at 800-MOLDS or email hello@saniservice.com.
