Could filthy AC coils be making my family sick?« Back to Previous Page

Yes, filthy AC coils can absolutely be the source of your family's symptoms. The combination of thick dust and black mold on the evaporator coil is a classic culprit for poor indoor air quality, especially in Dubai's climate where we rely on AC year-round.

The damp, dark environment behind the dust layer is an ideal breeding ground for mold and bacteria. Every time the AC turns on, it can blast these contaminants—along with dust mite allergens and other particulates—throughout your apartment. This directly explains the persistent coughing and headaches, as these are common reactions to inhaling mold spores and fine dust. Children are often more susceptible to these irritants.

A standard cleaning might resolve the issue if the contamination is only on the surface. However, given the description of caked-on dust and visible mold, and the fact it hasn't been serviced in three years, a deeper professional cleaning is strongly advised. In many JVC apartments, units are undersized for the space and run constantly, accelerating this buildup.

The cleaning must be thorough. Simply spraying a disinfectant won't remove the biomass fueling the problem. The coil needs to be mechanically cleaned to physically remove the debris. After a proper cleaning, symptoms often improve noticeably within a few days as the irritant source is removed. For documented results, a company with microbiology capabilities can test the dust to identify specific contaminants.
