AC mold causing my daily cough and stuffy nose?« Back to Previous Page

Based on the symptoms you've described and the visible mold growth, it is highly probable that the mold colony under your carpet is the direct cause of your persistent stuffy nose and dry cough. These are classic symptoms of mold exposure, which can cause allergic rhinitis and respiratory irritation. The continuous operation of your AC unit has likely been aerosolizing the mold spores from the damp carpet and distributing them throughout the bedroom air, which you then inhale throughout the night.

In Dubai's climate, where high humidity is constant, a leaking AC unit creates a perfect microenvironment for rapid mold proliferation. The condensation and dampness provide the moisture, the carpet and dust provide the organic food source, and the warm climate accelerates growth. The black and green coloration suggests a potentially toxigenic species like Aspergillus or Stachybotrys, which require professional handling.

Do not attempt to clean this yourself. Disturbing the colony without proper containment will release a massive cloud of spores, exacerbating your health issues and contaminating other areas of your home. DIY cleaning solutions are ineffective against entrenched growth and can pose chemical hazards.

The safest and most effective course of action is to engage a professional mold remediation company like Saniservice. Our certified technicians will first conduct a thorough inspection and air quality testing to identify the species and spore count. The remediation process involves strict containment with negative air pressure, HEPA filtration, safe removal of contaminated materials (carpet, padding), and application of EPA-approved antimicrobial agents. We also identify and rectify the source of the moisture—in this case, repairing the AC drain line to prevent recurrence.

For immediate assistance and to schedule a professional inspection, I strongly recommend you call Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com. Addressing this promptly is crucial for your health and the integrity of your property.
