How to clean AC ducts for dry throats and mildew smell?« Back to Previous Page

Based on the symptoms you're describing – the dry, scratchy throats and that mildew smell – your instincts are spot on; the AC system is almost certainly the source. In a Jumeirah Park villa running 24/7, this is a classic case of microbial contamination exacerbated by our extreme humidity and continuous operation.

For a DIY approach, you can start by replacing the air filters with a high-quality, high-MERV rating filter. Vacuum the accessible supply and return air grilles thoroughly. However, I must be frank: a true duct cleaning requires specialized equipment like truck-mounted HEPA vacuums and rotary brushes that you simply can't access as a homeowner. More critically, that mildew smell indicates active microbial growth, likely on the cooling coils or in the drain pan, which DIY methods won't effectively address. Improper cleaning can actually dislodge and spread contaminants throughout the entire villa.

Given the health symptoms, this isn't just about dust. The UAE's DM Circular No. 196 mandates specific hygiene standards for AC systems to protect indoor air quality, a standard DIY can't meet. For a villa of that size and the issues described, a professional hygienization service is not just recommended, it's essential. They will perform a full assessment, HEPA-vac the entire duct system, and most importantly, apply an EPA-approved biocidal treatment to the coils and ducts to eradicate the mold and bacteria causing the smell and irritation.

For a proper inspection and to get that air healthy again for your family, I'd strongly advise calling our certified team. Call 800-MOLDS or 800-66537 to schedule an assessment, or you can email us at hello@saniservice.com.
