How urgent is mildew near air conditioner?« Back to Previous Page

After the heavy rain last month, I noticed a strange musty smell coming from the corner of my bedroom. Upon closer inspection, I saw some mildew starting to form on the walls near the window. This concerns me because it’s right above where the air conditioner unit is placed. How urgent do you think this issue is and what should I do first?

The presence of mildew near your air conditioner unit is indeed concerning and should be addressed promptly. Mildew growth can lead to deterioration of the building materials and poses health risks due to potential mold spore dispersion, especially considering the humid conditions post heavy rain.

In the UAE, including Dubai, regulations regarding indoor environmental quality are stringent. The Health and Safety Law (Federal Decree-Law No. 32 of 2005) mandates that employers ensure a safe working environment, which includes maintaining indoor air quality free from mold contamination. Therefore, your case warrants immediate attention.

The first step you should take is to call the professionals at Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com for an expert assessment of the situation. A certified mold inspector can conduct a thorough evaluation, identifying the extent of the mildew and ensuring it hasn't spread to other parts of your home.

It's crucial to prevent the growth from spreading further by sealing off the area temporarily until professional help arrives. Use plastic sheeting or tarps to isolate the affected room. Ensure that you wear protective clothing when entering the area, including gloves and a mask designed for mold exposure.

While waiting for professionals, here are some steps you can take:
• Increase airflow in the area with a fan if possible, but avoid directly blowing air onto the mildew.
• Clean the area using a solution of 1 cup bleach to one gallon of water (use a higher concentration for tougher stains) and a scrub brush. Make sure to clean all surfaces where mildew is present.
• Ensure proper ventilation in your air conditioner unit. Check filters, coils, and drainage systems for any blockages or signs of moisture accumulation.

Remember that the effectiveness of DIY cleaning can be limited, especially if there’s extensive growth or if the underlying conditions causing the mold are not corrected. Professional remediation services will have the necessary expertise and equipment to thoroughly clean and treat the area, ensuring a healthier environment for your home.

Stay vigilant about indoor humidity levels in Dubai—high humidity is one of the main contributors to mold growth. Using dehumidifiers or air conditioners can help maintain optimal conditions. Regular inspections are also recommended to catch any issues before they become problematic.

In conclusion, treating mildew near an air conditioner unit isn’t just a matter of aesthetics—it's about protecting your health and property. Seek professional assistance quickly to address this issue effectively.
