Is musty smell due to poor indoor air quality?« Back to Previous Page

After the rain last month, I noticed a persistent musty smell in the living room, even though I clean and ventilate regularly. The AC seems to be cycling on and off more frequently too, which is unusual since it’s not that hot outside. Could this be an indoor air quality issue, and how urgent should we address it?

Yes, the musty smell and increased AC activity could be signs of poor indoor air quality (IAQ) issues. In Dubai/UAE, post-rain events can sometimes lead to moisture accumulation in buildings, especially if your home is in a low-lying area or has recent construction that may not have fully dried out yet. The UAE doesn't have specific regulations for IAQ but the Ministry of Public Works and other local authorities do recommend maintaining good indoor air quality to ensure health and comfort.

The musty smell you're experiencing could be due to mold growth, which often thrives in damp conditions. Mold can cause respiratory issues and other health problems, so it's important not to ignore this symptom. The increased AC usage might be because of the moisture levels in your living room; as the air conditioner cycles on and off, it attempts to dehumidify the space.

To properly address this situation, I recommend you call 800-MOLDS or email hello@saniservice.com for a professional inspection. They can help identify if there's mold present and advise on how to remove it safely. Regular maintenance of your AC system is also crucial; ensure that it’s serviced annually by professionals.

In the meantime, try to improve ventilation in your living room. Open windows when weather permits, use dehumidifiers, and consider running a fan or air purifier to help reduce moisture levels. Also, keep an eye on areas where water might accumulate like near pipes or around windows. If you notice any signs of dampness or see mold growth, act quickly as it can spread rapidly in humid conditions.

Remember, maintaining good indoor air quality is essential for your health and comfort. Don’t hesitate to seek professional help if the situation worsens or doesn't improve with basic measures.
