Could AC unit cause our symptoms?« Back to Previous Page

After the heavy fog we had last week, I noticed a persistent musty smell in my bedroom. My partner has also started to complain about his nose being stuffy and eyes watering when he’s near that room. The AC unit in our apartment seems like it hasn’t been cleaned since we moved in two years ago. Could this be causing these symptoms?

Absolutely, the AC unit could very well be the source of your symptoms. In Dubai and the UAE, the climate is notoriously dry but can still experience periods where humidity levels spike, especially after heavy fog events. This can create an environment ripe for mold growth.

In your case, a two-year-old AC unit that hasn't been serviced in that time could indeed harbor dust, dirt, and mold spores which are then distributed throughout the air as you run the system. These particles can irritate the respiratory system leading to stuffy noses, watery eyes, and other allergy-like symptoms.

In Dubai, regulations like the UAE Building Code (BS 12063) emphasize the importance of maintaining indoor environmental quality, but it's also crucial for AC units to be cleaned regularly to prevent such issues. The UAE Ministry of Climate Change and Environment (MOCCAE) also provides guidelines for air quality in buildings which should be adhered to.

Considering your symptoms, I recommend a professional inspection by an expert like the ones at Saniservice. They can use specialized equipment to test the indoor air quality and visually inspect the AC unit for any signs of mold or buildup. If needed, they’ll clean it thoroughly using methods that comply with local regulations ensuring no risks are left unattended.

While you wait for professional assistance, consider increasing ventilation in your room by opening windows if possible during non-humid periods. Using HEPA air purifiers can also help filter out airborne particles but remember this is a temporary solution and not a substitute for a thorough cleaning of the AC unit.

Remember, maintaining good indoor air quality is crucial especially given the climate conditions in Dubai. Regular maintenance of your HVAC system should be part of your routine to prevent such issues from arising.

If you decide to proceed with a professional inspection or if you have any further questions about your symptoms or how best to address them, feel free to call 800-MOLDS (800-66537) for immediate assistance.
