Is poor duct cleaning causing our symptoms?« Back to Previous Page

After the heavy dust storm last month, I noticed a persistent cough and runny nose whenever we turn on the air conditioner in our living room. The vents are also releasing this fine gray dust that settles everywhere. Could this be due to poor duct cleaning? What should I do to ensure my family’s health?

Yes, poor duct cleaning could very well be the culprit behind your symptoms. In Dubai and throughout the UAE, dust storms can indeed deposit a significant amount of fine particulate matter into the air. When this dust gets trapped within the HVAC system's ductwork, it can become airborne again whenever you activate the air conditioner or heater.

In recent months, we've seen an increase in similar complaints from clients who have experienced coughing and runny noses after using their AC units post-dust storms. The fine gray dust that you mentioned settling everywhere could easily be remnants of this storm debris, along with other contaminants like mold spores, pet dander, and even pests that may have found their way into the ducts.

Given your situation in Dubai, it's highly recommended to schedule a professional inspection of your HVAC system. The UAE doesn't specifically regulate duct cleaning at a federal level, but local authorities such as the Department of Municipalities and Urban Planning (DM&UP) do enforce cleanliness standards for public buildings; though these might not directly apply to residential settings.

However, having a professional like SaniService conduct a thorough inspection can help identify whether your symptoms are indeed linked to poor duct hygiene. Our team utilizes advanced tools such as video cameras to inspect the condition of your ductwork and offer targeted cleaning solutions. We follow best practices recommended by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) which is recognized globally.

If a professional inspection confirms the presence of excessive dust or contaminants in your ducts, we recommend our comprehensive duct cleaning services. Our process includes vacuuming all accessible surfaces inside the ductwork, using specialized brushes to scrub away stubborn deposits, and sealing any gaps or leaks that could allow further contamination.

To take proactive measures, it's also advised to regularly maintain your HVAC system by changing filters every 3-6 months depending on usage, especially during high-dust periods. Additionally, consider having a humidifier in your home to help keep the air moist, reducing the chances of mold growth which can exacerbate respiratory issues.

Remember, if you're dealing with persistent symptoms or if conditions worsen despite cleaning efforts, it might be wise to consult an allergist who can conduct tests for allergies and other potential health concerns. Always ensure that any service provider you engage complies with local standards and is certified by relevant authorities.
