Is AC coil cleaning linked to musty odor and coughing?« Back to Previous Page

After the heavy dust storms last month, I noticed a persistent musty odor in my bedroom, especially when the air conditioning is on. My kids have been experiencing frequent coughing fits, and it’s made me wonder if the coil cleaning might be to blame. Have any of you experienced similar issues or know what could be causing this?

Yes, AC coil cleaning can indeed be linked to musty odors and coughing. In the UAE, especially during dusty periods like those we experienced recently, air conditioning systems can accumulate a lot of dust and other particulates over time. This buildup can lead to mold growth, particularly on coils which are often hidden from view but play a crucial role in your unit's efficiency.

In Dubai, there have been several instances where improper maintenance or neglect of AC units has resulted in similar issues. Mold growing on the evaporator coil is a common culprit for musty odors, especially when the air conditioning is turned on. The moist environment inside the unit provides an ideal breeding ground for mold spores which can then be circulated throughout your home via the ventilation system.

For those experiencing frequent coughing fits in their children or other family members, it’s crucial to address this issue promptly. Mold exposure, particularly among younger individuals, can exacerbate respiratory issues and contribute to allergies.

If you suspect that AC coil cleaning might be linked to these symptoms, I recommend scheduling a professional inspection by calling 800-MOLDS or emailing hello@saniservice.com. Regular maintenance of your HVAC system is vital for ensuring good indoor air quality, especially in regions prone to dust storms like the UAE.

Remember, maintaining clean and properly functioning AC units not only improves comfort but also enhances overall health. By keeping up with regular cleaning and inspection, you can help prevent musty odors and other potential health issues associated with poor air quality.

Don't wait until the next storm hits – proactive measures now could make a big difference in your home's environment.
