Should AC unit cause wall mildew?« Back to Previous Page

The humidity produced by air conditioning units can indeed contribute to the growth of mold and mildew, especially under the right conditions. In dubai, where we experience relatively low humidity most of the year, the situation you described might seem unusual but is not entirely uncommon in specific scenarios.

In your case, the dampness near your AC unit and the formation of mildew suggest that there could be an issue with moisture management or air circulation within your room. The window AC unit can create a localized environment with higher humidity levels than the surrounding area if it's not properly ventilated. This is due to the fact that during operation, the AC condenses water from the indoor air and releases this moisture back into the room.

UAE standards and regulations (such as those outlined in EN 13240 for air conditioning systems) require proper design and installation of HVAC systems to ensure they do not contribute to moisture issues. However, there are instances where improper installation or maintenance can lead to such problems. For example, if the drain line from the AC is blocked or improperly installed, it can cause water to pool behind the unit, leading to dampness and eventually mold.

It's important to assess whether your AC unit is properly sealed to prevent moisture intrusion and ensure adequate ventilation in the room. Additionally, regular maintenance of your AC system is crucial for its efficiency and longevity as well as preventing these kinds of issues.

Given the specific conditions you've described, it would be prudent to conduct a professional inspection by calling 800-MOLDS or emailing hello@saniservice.com. They can provide a thorough evaluation and recommend any necessary remediation steps to address the mold growth and ensure your indoor environment remains healthy.

Remember that in Dubai, maintaining good indoor air quality is not only about temperature control but also about managing humidity levels effectively. A well-maintained AC system should not be contributing to moisture issues, so identifying the root cause of this problem can help prevent future occurrences and keep your living space safe and comfortable.
