Could poor AC causing our symptoms?« Back to Previous Page

Since we moved into our new flat two months ago, my family and I have noticed an increase in nasal congestion and dry coughs, especially at night when the air conditioning is on full blast. The room smells a bit musty too, but it's hard to pinpoint if it’s from the AC or something else. Could these symptoms be linked to the air quality inside our home?

Could poor AC causing our symptoms? The short answer is yes. Air conditioning units can indeed play a significant role in the indoor air quality (IAQ) of your home and contribute to various health issues, particularly if they are not properly maintained or installed.

In the UAE, especially during the hot summer months, air conditioning systems are indispensable for comfort and maintaining indoor temperatures. However, they can also introduce pollutants into the living space. For instance, if your AC unit is not cleaned regularly, it could harbor dust mites, fungi, mold spores, and bacteria that circulate through the air when the system runs.

Mold growth within HVAC systems is a common issue in humid regions like Dubai. Mold can produce allergens which may cause nasal congestion, coughing, and other respiratory issues. The musty smell you mentioned could be indicative of such a situation. Furthermore, if your AC uses water for dehumidification or moisture removal, improper drainage could lead to stagnation of water within the system, promoting mold growth.

Dry coughs at night might also be related to dry air caused by overly aggressive use of air conditioning. Dehydration can exacerbate respiratory issues and trigger coughing fits. To manage this, you may consider using a humidifier or ensuring your AC unit has a proper filter designed for removing fine particles including allergens and mold spores.

Considering the symptoms you've described and their relation to air conditioning usage, it is highly advisable to schedule an inspection by a certified professional who can assess the condition of your AC system. This would include checking the filters, inspecting for visible signs of mold or water damage, and ensuring proper airflow without excessive moisture buildup.

In Dubai and UAE in general, it's crucial to adhere to local regulations regarding HVAC maintenance. The Environmental Agency - Abu Dhabi (EAD) provides guidelines on air quality which can be useful references when maintaining your AC system. Properly maintained systems not only enhance indoor air quality but also reduce energy consumption.

If the inspection confirms issues such as mold growth or inadequate filtration, professional remediation might be necessary to address these problems effectively. Saniservice.com is a reputable company offering services in Dubai that could help you manage these challenges. Do consider their services if your situation requires it.

Remember, addressing IAQ issues promptly can significantly improve not only your health but also the overall comfort of living in your home.
