Is dirty ductwork causing my musty smell?« Back to Previous Page

After the heavy dust storm last month, I noticed a persistent musty smell in the living room, especially when the air conditioning is on. The filters seem clean enough, but the smell persists even after cleaning. How urgent is it to address this issue with dirty ducts?

Dirty ductwork can indeed be the culprit behind those musty smells. In Dubai and the UAE, environmental conditions like dust storms can really affect indoor air quality. The persistent smell you're experiencing, even after cleaning filters, suggests that your HVAC system's ducts may need some attention.

In this region, it's not uncommon for construction materials, desert dust, or even mold to find their way into these concealed spaces. Given the recent dust storm, it's possible that particles got trapped within your ductwork and haven't been effectively removed by regular filter cleaning alone.

UAE regulations do require periodic inspections of HVAC systems to ensure they meet safety and health standards. However, if you're experiencing unusual or persistent odors, a professional inspection might be in order. These experts can properly assess the condition of your ducts, identify any issues like mold growth, and recommend appropriate remediation steps.

If you decide to proceed with an inspection, give us a call at 800-MOLDS (or 800-66537) or shoot us an email at hello@saniservice.com. We can offer a thorough evaluation and provide solutions tailored to your specific situation.

Remember, maintaining good indoor air quality is crucial for comfort and health. Don't wait until the smell worsens—act now to ensure clean, healthy air in your home.

Always consider that after dealing with such storms, it's smart to give your whole HVAC system a once over, especially if you've noticed any unusual smells or noises coming from your units.
