Could mold in our AC cause allergy symptoms?« Back to Previous Page

Based on your description, it is highly probable that mold growth within your AC unit is the direct cause of the allergy-like symptoms you and your husband are experiencing. The damp, earthy smell is a classic indicator of microbial volatile organic compounds (MVOCs), which are gasses produced by actively growing mold colonies. The black specks visible around the vent are likely the mold spores themselves.

In the Dubai climate, where high humidity and constant AC use create significant condensation, AC systems are a prime breeding ground for mold. When the unit operates, it aerosolizes these spores and MVOCs, blowing them directly into your breathing zone throughout the night. This prolonged exposure can irritate the respiratory tract, leading to the symptoms you've described: nasal congestion, itchy eyes, and throat irritation.

You should not attempt to clean this yourself. Disturbing the colony without proper containment and equipment can cause a massive release of spores, exacerbating the problem and contaminating other areas of your home. This requires professional assessment and remediation.

I strongly recommend you call a certified mold inspection and remediation company. We at Saniservice specialize in this exact scenario. Our process involves a thorough inspection using borescopes to assess the internal ductwork and evaporator coils, followed by a professional hygienization process that includes antimicrobial fogging to eliminate the growth at its source, not just wipe it superficially.

For a proper inspection and to discuss a remediation plan, please call us at 800-MOLDS (800-66537) or email hello@saniservice.com.
