Is constant AC running due to mold growth?« Back to Previous Page

The AC in my apartment seems to be running a bit differently lately; it’s not as loud as before, but I’ve noticed it’s on almost non-stop. My kids have been coughing and sneezing more than usual, especially when they come home from school. The windows are usually open to catch the sea breeze, but today I noticed some dust settling in the corners of the room even though it hadn’t rained for days. Could this be an issue with mold or allergies?

The constant running of the air conditioning (AC) in your apartment and the observed changes such as an increase in coughing and sneezing by your kids could indeed be indicative of a problematic indoor environment. In the UAE, particularly in Dubai, humidity levels can fluctuate significantly, often leading to conditions that favor mold growth. Mold thrives in damp environments with relative humidity above 60%, which is common during certain seasons.

The non-stop operation of the AC suggests it might be working harder than usual to maintain comfort levels, possibly due to increased air leakage or a build-up of contaminants like dust and allergens. The fact that you've noticed dust settling even when the windows are usually open indicates a potential issue with indoor air quality. This could be related to poor ventilation or an increase in airborne particles.

Given the symptoms your kids are experiencing, it's prudent to consider the possibility of mold growth or other indoor pollutants. In Dubai and the UAE, there is no specific regulation mandating regular mold inspections, but it is highly recommended to have a professional assessment if you suspect any issues.

To address this situation, I would advise contacting a certified environmental inspection and remediation company in the region such as Saniservice at 800-MOLDS (800-66537) or by email at hello@saniservice.com. They can conduct a thorough assessment of your apartment's air quality and inspect for any signs of mold, dust mites, or other allergens.

In the meantime, you could take some preliminary steps to improve indoor air quality:
1. Ensure proper ventilation: Even if windows are usually open, make sure there is adequate airflow to reduce moisture levels.
2. Use dehumidifiers: These can help control humidity and prevent mold growth in areas prone to condensation.
3. Regular cleaning: Dust and vacuum regularly, especially areas where dust tends to settle like corners.
4. Keep indoor plants to a minimum if they are causing additional dust or humidity.

Remember, while these steps may alleviate some symptoms, professional intervention is crucial for addressing the root cause of any health concerns linked to your home's environment.
