Is old AC causing mustiness and mold?« Back to Previous Page

Is old AC causing mustiness and mold? Yes, it's quite probable that your situation is related to an outdated air conditioning system. In the UAE, particularly in Dubai, humidity can be a significant factor, especially after rain events which seem to exacerbate issues.

In recent years, there have been several instances reported of similar problems arising from poorly maintained AC units. The musty smell and coughing experienced by your children could indeed be indicative of mold growth. Mold thrives in damp conditions, and an old AC unit that hasn't had regular servicing can become a breeding ground for it.

According to the UAE's Building Environmental Code (BEC), regular maintenance is crucial for ensuring good indoor air quality (IAQ). The code recommends inspecting and maintaining HVAC systems at least annually. Since your AC has not been serviced in over two years, it's highly likely that this neglect could be contributing to the mold problem you're experiencing.

To address this issue effectively:

1. Professional Inspection: Contact a certified environmental inspection company such as Saniservice (call 800-MOLDS or email hello@saniservice.com). They can perform a thorough assessment of your AC unit and indoor environment, including air sampling to identify mold spores.

2. Service Your AC: Have the system professionally serviced immediately. This includes cleaning the evaporator coils, checking for leaks, and ensuring that the drain pan is functioning properly to avoid water accumulation which promotes mold growth.

3. Dehumidification: Consider using a portable dehumidifier in the bedroom if the problem persists. Keeping relative humidity levels below 60% can significantly reduce mold proliferation.

4. Ventilation: Ensure proper ventilation within your home, especially in areas prone to moisture like bathrooms and kitchens. This helps reduce overall indoor humidity levels.

5. Clean Surfaces Regularly: Use a solution of water and detergent to clean surfaces that are susceptible to mold growth. Pay special attention to corners and behind furniture where dust and moisture can accumulate unnoticed.

6. Seal Gaps and Cracks: Inspect your home for any gaps or cracks through which outdoor humidity might seep indoors, especially around windows and doors. Sealing these areas can help maintain a more controlled indoor environment.

7. Regular Cleaning of Ductwork: If feasible, have the ducts cleaned by professionals every few years to remove accumulated dust and debris that could harbor mold spores.

By addressing your AC unit promptly and implementing these measures, you should see an improvement in the musty smell and respiratory issues experienced by your children. Remember, proactive maintenance is key to maintaining good IAQ in Dubai's humid climate conditions.
