Why is mold growing despite running AC?« Back to Previous Page

The growth of mold despite the air conditioning (AC) system running constantly could be due to several factors, some of which are common challenges faced by property owners in the UAE. In Dubai, humidity levels can fluctuate dramatically, especially during rainy seasons or near bodies of water. The AC may not be equipped to handle these conditions effectively, leading to moisture accumulation and subsequent mold growth.

Firstly, it's crucial to understand that air conditioning systems primarily aim at cooling air, but they do not always manage the relative humidity (RH) within a space efficiently. In fact, many AC units in Dubai might increase RH by drying out the air excessively, which can lead to condensation on cold surfaces like windows or ceilings, particularly during transitions from hot, humid outdoors to cool indoor conditions.

Another factor could be poor ventilation. Even with an efficient AC system, insufficient airflow can cause pockets of stagnant air that retain moisture and promote mold growth. In Dubai apartments, especially those in older buildings without advanced air management systems, this issue is not uncommon.

Additionally, leaks or dampness around windows or other parts of the building envelope can introduce moisture directly into the space. It's important to inspect these areas for any signs of water intrusion, which can be exacerbated by heavy rains like you've experienced.

Given your situation, a professional inspection and remediation service would be advisable. Saniservice (hello@saniservice.com) or other reputable companies in the UAE specialize in mold assessment and treatment. They can provide detailed analysis, recommend appropriate measures, and ensure that all necessary steps are taken to prevent future recurrence.

In terms of immediate actions you can take:
1. Increase ventilation: Open windows when weather permits to allow fresh air circulation.
2. Use dehumidifiers: These can be particularly useful in areas prone to high humidity or after rainy periods.
3. Address any leaks promptly: Inspect and repair any plumbing issues or roof leaks immediately.

Remember, mold growth can pose health risks, so it's important not to delay addressing the issue. Professional guidance is recommended for comprehensive remediation and prevention strategies tailored to your specific property conditions in Dubai.
