Is our HVAC system affecting my daughter's cough?« Back to Previous Page

The AC in my apartment seems to be running a bit differently since we moved into our new unit. It’s louder than before, and sometimes it feels like there's a strange smell coming from it, almost like chemicals or old insulation. My daughter has been complaining of a persistent cough, and I'm starting to wonder if the air quality here could be affecting her. Could it be related to poorly certified HVAC systems? What should I look for when checking if our AC unit is properly certified in Dubai?

The symptoms your daughter is experiencing could indeed be linked to poor indoor air quality, especially given the unusual smells and sounds from the HVAC system. In Dubai and the UAE, it's crucial to ensure that all installed systems comply with local regulations such as EN 13779 for residential HVAC units, which sets standards for fan coil units, heat pumps, and other systems.

When evaluating your system, several factors should be considered:

Firstly, a certified HVAC unit must meet the stringent requirements set by the Emirates Standards Authority (ESA), ensuring it operates efficiently without excessive noise. The loudest part of an AC unit is typically the condenser or blower fan; if you're experiencing increased noise levels, there may be issues with these components. It's important to inspect them for cleanliness and ensure they are free from obstructions.

Secondly, check your air filters regularly. Dirty or clogged filters can cause the system to work harder, potentially leading to higher noise levels and decreased airflow. Ensure you're using high-quality filters that meet local standards like EN 13779 Part 2, which focuses on the performance of HVAC equipment in terms of airflow.

Regarding the smell, it could be indicative of several issues such as mold growth, improper venting, or even a malfunctioning air conditioning unit. In Dubai, where extreme temperatures are common, humidity can exacerbate problems like mold if not properly managed by your system. Consulting with an environmental inspection company would be prudent to address any potential health concerns.

Given the symptoms and the unusual smells you're noticing, it might be wise to schedule a professional inspection. Such inspections should cover areas such as the integrity of the ductwork, proper installation of the HVAC unit, and the presence of any moisture issues that could lead to mold growth. Companies like Saniservice, which can be contacted via 800-MOLDS or hello@saniservice.com, are equipped with specialists who understand the specific challenges faced in Dubai's climate.

In summary, while it’s easy to attribute symptoms such as coughing to a common cold, persistent issues might need professional attention. Ensuring your HVAC system is certified and regularly maintained according to UAE standards can significantly improve indoor air quality and potentially alleviate symptoms like those experienced by your daughter.
