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

After the recent heavy rains last month, I noticed a musty smell coming from the bedroom closet. My kids have been coughing and sneezing more than usual since then. Could this be related to poor duct sealing in our apartment? What signs should I look for that indicate whether we need professional help with duct sealing?

Duct sealing is indeed a critical aspect of indoor environmental quality and can have significant impacts on your living conditions. The symptoms you're experiencing—musty smell and increased coughing/sneezing among family members—are definitely worth investigating, especially if they seem to coincide with recent weather events like the heavy rains we've seen in Dubai.

In the UAE, particularly in places like Dubai, poor duct sealing can lead to a variety of issues. Dampness or moisture within your air ducts could create an ideal environment for mold growth, which might explain that musty odor and your kids' respiratory symptoms. Mold spores can travel through your HVAC system and be distributed throughout the apartment, leading to allergic reactions.

Some signs you should look out for include:
• Dark spots or discoloration on the inside of your air vents
• A noticeable increase in dust or dirt accumulating around ventilation areas
• Persistent musty odors in certain parts of your home, especially after rain events

If you're unsure about what's causing these issues or if they persist despite some basic maintenance efforts, it might be prudent to call for a professional inspection. In the UAE, companies like Saniservice offer reliable services for duct sealing and remediation. You can contact them on 800-MOLDS (800-66537) or email hello@saniservice.com.

Remember, proper duct sealing not only helps in maintaining a healthy indoor environment but also improves your energy efficiency by reducing the strain on your HVAC system. Ensuring that your air ducts are properly sealed can significantly cut down on unwanted airborne contaminants and allergens, making your home more comfortable for everyone, especially during the cooler months or after weather events like heavy rains.

Taking proactive steps now could save you from bigger issues later, so don't delay in seeking professional advice if needed.
