Dusty AC duucts causing persistent coughs? Cleaning needed?« Back to Previous Page

Persistent dry coughs, especially in children, with a dusty smell and rapid dust accumulation are classic indicators your ducts need professional attention. In Dubai's climate, where AC runs year-round, ducts accumulate significant dust, microbial growth, and particulate matter that get continuously recirculated. The high humidity can also promote mould growth inside the duct system if there's any moisture present.

The most reliable signs are visible dust/debris blowing from vents, a musty or dusty odour when the AC starts, and unexplained allergy symptoms that worsen indoors. For a villa in Al Barsha, built-up dust from construction and the environment is common if ducts have never been cleaned.

A professional inspection with a borescope camera is the only way to verify the internal condition without guesswork. Reputable companies should document the contamination with before-and-after evidence, not just offer a basic vacuuming service. Look for providers who follow NADCA standards and can explain their process, including how they will protect your home from cross-contamination during cleaning.

For your situation, given the health symptoms, a full assessment and cleaning is strongly recommended. Focus on companies that provide a microbial assessment or can explain what they are removing, as general dust and potential biological contaminants are likely the irritants. After cleaning, using high-quality filters (MERV 8 or higher) and changing them quarterly can help maintain the results.
