Could ductwork issues cause our home smells and coughs?« Back to Previous Page

After the heavy dust storm last month, I noticed a strange smell lingering in my bedroom. It's almost like an earthy odor that gets stronger when the air conditioning turns on. My kids have also been coughing more frequently lately, which has me worried about the quality of the air we’re breathing. Could this be related to our ductwork? What should I look for when having the ducts cleaned to prevent such issues in the future?

Could ductwork issues cause our home smells and coughs? Indeed they can. The dust storm you mentioned last month might have been the catalyst for a lot of debris to find its way into your HVAC system, leading to potential blockages and accumulation within the ductwork. This can introduce unpleasant odors like earthy scents as well as contribute to respiratory issues, especially in kids who are more susceptible.

In dubai uae, our climate with frequent dust storms, humidity changes, and even sandstorms can be a nightmare for indoor air quality. These conditions often lead to the build-up of microorganisms, mold spores, pollen, dirt, and other particulates that can circulate through your ducts. When these accumulate, they not only affect the freshness of the air but can also exacerbate allergy symptoms or trigger asthma attacks.

The earthy smell you describe is a classic sign of mold growth. Mold thrives in damp environments like those found within HVAC systems during summer when AC units are running frequently. It's important to address this issue promptly as exposure to mold spores over time can lead to chronic health issues, particularly for children and the elderly.

For your case, it would be wise to have a professional inspection carried out. The UAE has specific regulations regarding indoor environmental quality that professionals must adhere to when conducting such services. Companies like Saniservice who operate in Dubai are well-versed with these standards and can provide you with a thorough assessment of your ductwork.

During the cleaning process, look for companies that use EPA-approved methods and equipment. This ensures they properly clean all surfaces including inner linings, registers, and grills to remove contaminants effectively. They should also follow post-cleaning procedures like air filtration or fogging treatments if necessary to ensure no residual mold spores are left behind.

To prevent such issues in the future, regular maintenance of your HVAC system is crucial. This includes cleaning or replacing filters every 3-6 months depending on use and environment, ensuring proper outdoor unit maintenance to avoid condensation build-up which can foster microbial growth, and scheduling professional duct cleaning at least once a year, especially after severe weather events.

If you decide to proceed with cleaning or if you have concerns about your air quality, don't hesitate to contact Saniservice. Their team is ready to assist you in maintaining the health of your home environment. Call 800-MOLDS or email hello@saniservice.com for more information and a quote.
