Is AC setup causing my child's symptoms?« Back to Previous Page

After the recent heatwave, I’ve noticed my 5-year-old daughter seems a bit off. She’s had more frequent nosebleeds and coughs since we turned on the AC in the living room every evening. The temperature is perfect for us, but I’m worried about her. Could there be something wrong with how we’re setting up the AC or am I overthinking it?

Absolutely, the setup and maintenance of your air conditioning (AC) system can indeed impact indoor environmental quality significantly. Given that you're experiencing symptoms like frequent nosebleeds and coughs, it's crucial to review several aspects of your AC operation and environment.

Firstly, it's important to know that in the UAE, specifically Dubai, there are stringent guidelines for air conditioning systems to ensure they do not contribute to poor indoor air quality. The Emirates Standards Authority (ESA) sets standards for HVAC systems which include regular maintenance schedules and filter replacements every 30-90 days depending on usage and environmental conditions.

The AC setup in your living room may be too cold, causing the air to become excessively dry. This can irritate mucous membranes, including those of the nose, leading to increased susceptibility to nosebleeds and coughs. In Dubai's climate, it’s often recommended to keep indoor temperatures between 24°C to 26°C for comfort while reducing strain on systems.

Another factor could be the use of air purifiers or humidifiers in conjunction with your AC unit. If not properly maintained, these devices can become breeding grounds for bacteria and molds. Regular cleaning and maintenance are essential. In Dubai, it's advised to clean and service your HVAC units at least twice a year by certified professionals.

It’s also worth considering the quality of the air filters you’re using. High-efficiency particulate air (HEPA) filters can effectively remove allergens, but they need to be replaced regularly according to manufacturer guidelines or when they start showing signs of clogging.

Lastly, if these symptoms persist despite making adjustments, it would be wise to contact a professional environmental inspection and remediation company such as ours at 800-MOLDS (800-66537) or email hello@saniservice.com. They can conduct a thorough assessment of your AC system and indoor environment, ensuring they meet the necessary standards for health and comfort.

Remember, maintaining proper ventilation is key in Dubai’s climate, so it's also important to ensure that windows are not sealed shut during periods when you're relying heavily on your AC systems.

Taking these steps can help create a healthier indoor environment for your family.
