How to clean AC and stop mold in our villa?« Back to Previous Page

The AC in our villa in Jumeirah seems to be making our whole ground floor feel damp, and we’ve started seeing these small black spots along the bottom of the curtains in the living room. We run the AC constantly but the air just doesn't feel dry anymore. What’s the most effective way to clean the unit and prevent this mold from spreading further into the furniture?

Based on your description of dampness on the ground floor and visible black spots on the curtains, you are likely dealing with a mold issue originating from your air conditioning system, a common problem exacerbated by Dubai's high humidity and constant AC use. The damp feeling indicates excessive moisture, often due to a clogged condensate drain line or a dirty evaporator coil, which creates the perfect environment for mold growth inside the AC unit, which is then circulated throughout your villa.

For a comprehensive solution, a professional inspection is strongly recommended. DIY cleaning of internal components is not advisable and can often spread spores or damage the sensitive system. Our certified technicians perform a detailed assessment that includes using borescopes to inspect internal ductwork and air quality testing to identify the mold species and spore concentration, which is crucial for determining the correct remediation protocol, in line with Dubai Municipality's health and environmental standards.

The most effective remediation process involves several technical steps: isolating the affected area with negative air pressure, a thorough HVAC system hygienization using EPA-approved biocides, and mechanically cleaning the evaporator coils and condensate drain pan. The entire duct system must be agitated and vacuumed using HEPA filtration equipment. Finally, applying a mold-resistant sealant to the coils and implementing preventative measures, such as installing a UV-C light system within the AC unit, will inhibit future growth.

To properly address this and prevent further damage to your property and health, please contact our specialists for a professional assessment. Call Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection.
