Could AC causing my daughter's symptoms?« Back to Previous Page

The AC in my apartment seems to be running non-stop these days, even when it’s not very hot. Lately, my daughter has been complaining of a persistent cough and runny nose every time we use it. It smells slightly musty too, especially at night. Could this be causing her symptoms?

It sounds like the AC in your apartment might be contributing to your daughter's symptoms. The persistent cough and runny nose alongside the musty smell can indicate indoor air quality issues that are common in Dubai's climate.

Firstly, it’s essential to understand that the air conditioning system acts as a significant factor affecting the indoor environment. In the UAE, especially during summer months, AC units often have filters that might not be cleaned regularly or properly maintained, leading to potential allergens and mold growth. The musty smell you've noticed can hint at microbial growth such as molds thriving in the cooling coils and ducts.

In Dubai, there are no specific regulations mandating regular maintenance of HVAC systems, but it is highly recommended for maintaining good indoor air quality (IAQ). Regular cleaning and inspection of your AC unit, including replacement of filters every 3-6 months depending on usage, can help mitigate some issues. Also, ensure that the AC has been properly installed and sealed to prevent any water leaks or condensation which might promote mold growth.

The continuous operation even when not required could be a sign of malfunctioning sensors or control systems. A professional HVAC inspection would provide insights into whether there are underlying mechanical problems causing this behavior.

Given your daughter's symptoms, it’s imperative that you address the issue promptly to avoid exacerbating any health conditions she might have. Persistent cough and runny nose can indicate allergies, which might be triggered by mold spores or other irritants in the air.

I strongly recommend scheduling a professional indoor environmental inspection with our company, Saniservice.
