Is HVAC odor linked to my daughter's cough?« Back to Previous Page

The AC in my apartment seems to be causing a strange odor that only comes on during the evenings, especially when the unit is running on high. My daughter has had a persistent cough since we moved into this building two years ago, and I can’t help but wonder if it’s related to the smell and the dusty feel of the air coming out of the vents. Has anyone else noticed something similar or experienced health issues linked to their HVAC system in Dubai?

Absolutely, the odour from your HVAC system and its potential link to your daughter's cough could be connected. In Dubai, as in many regions, there are various factors that can lead to such issues. First off, it is not uncommon for older or improperly maintained HVAC systems to harbor mold, bacteria, and other microorganisms which can release unpleasant odours and potentially trigger allergic reactions or respiratory issues, especially among children.

In the UAE, particularly in Dubai, humidity levels can vary significantly throughout the year, and this fluctuation often creates conditions that favor microbial growth. The high temperatures and dry air during summer months, coupled with less stringent regulation on indoor environmental quality compared to other regions, could exacerbate these issues if your system isn't properly serviced.

It's quite possible that what you're experiencing is a common occurrence in many buildings here. Dust, mold spores, and allergens from ducts can circulate through the air conditioning unit, leading to odours and affecting indoor air quality. These can be especially problematic for individuals with asthma or allergies like your daughter.

Given these concerns, it would be wise to schedule an inspection by a professional. The UAE has no specific laws mandating regular HVAC inspections, but adhering to best practices ensures that your home remains safe and healthy. You could consider calling 800-MOLDS or email hello@saniservice.com for a thorough assessment of your system.

While you wait for the inspection, it's also helpful to clean the air filters in your AC unit regularly – every one to three months is recommended. Ensuring that these are free from dust and debris can significantly reduce airborne contaminants.

Additionally, try using an air purifier equipped with a HEPA filter to capture smaller particles such as mold spores and bacteria. This step might not solve the root cause but can provide some immediate relief for your daughter's cough.

Remember, maintaining good indoor air quality is crucial in Dubai’s climatic conditions, and addressing these issues promptly could help alleviate both the odour problem and your daughter's symptoms.
