Could duct issues cause a damp smell?« Back to Previous Page

After the rain last month, I noticed a persistent damp smell in the living room, especially when the air conditioning is on. The filter seemed pretty clean, but given how much dust accumulates even with regular cleaning, I’m worried there might be more going on with the ducts. Have any of you experienced similar issues and what did you do to prevent it from happening again?

Yes, duct issues can absolutely cause a damp smell. The air conditioning system is like a giant pipeline for air flow; any blockage, moisture intrusion, or contamination within the ducts can affect indoor environmental quality. In Dubai and UAE, given the climate, it's not uncommon to experience such smells especially after heavy rains.

In your case, since you've noticed a damp smell in the living room particularly when the AC is on, it’s highly probable that there might be water intrusion or moisture accumulation within your ductwork. This can happen due to condensation, leaky joints, or even because of poor installation practices which aren't uncommon here.

I recommend having your ducts inspected by a professional. In Dubai, companies like Saniservice can offer thorough inspections and cleaning services that are in line with local regulations such as EN 779:2012 for air handling units. They'll be able to identify any potential issues and provide recommendations on how to prevent them from happening again.

Regular maintenance is key. While you mentioned your filter seemed clean, it's important to note that filters only catch part of the problem. Ducts can hold a lot more dust, debris, and moisture which isn’t filtered out. Saniservice or similar companies can use specialized equipment like vacuum cleaners with HEPA filters to clean your ductwork thoroughly.

To avoid future issues, consider sealing any gaps or leaks in your ductwork during maintenance visits. This will help prevent water from entering the system in case of heavy rains. Additionally, it might be wise to invest in a dehumidifier to keep moisture levels down in areas where you’re experiencing issues like your living room.

Remember, if you suspect mold growth due to these conditions, it's crucial to address it promptly as mold can pose serious health risks. Saniservice offers mold remediation services too, ensuring that not only is the air quality improved but also that any existing or potential mold is dealt with effectively.
