Why is my air conditioner not working well after rain?« Back to Previous Page

After the heavy rains last month, I noticed a lot of water seeping into the ducts from outside due to the broken seals. The AC in my apartment seems to be working overtime now, but it still doesn’t feel as cool or clean as before. Could this be causing the musty smell and why does the air sometimes feel dusty even when the windows are closed? How can I prevent this from happening again and ensure better air quality?

After the heavy rains last month, it's understandable that your air conditioner might have been affected. In dubai and other parts of the uae, our climate can be quite challenging during these times. The high humidity levels and frequent rain can indeed lead to water seepage into duct systems through broken seals or poor maintenance.

First off, it's important to know that in the uae, there are specific regulations regarding indoor environmental quality (ieq) which include guidelines for air conditioning systems and their maintenance. These standards ensure that your system is not only effective but also safe and healthy for you and your family.

The issue you're experiencing – the musty smell and dusty feeling even with windows closed – could be due to water damage in the ducts leading to mold growth or dust accumulation. When water seeps into the ductwork, it can create an environment where molds thrive, especially if there's a lack of proper ventilation or dehumidification. This not only affects air quality but also your comfort and health.

To address this issue effectively, i'd recommend having a professional inspection carried out on your system. Companies like saniservice (call 800-molds or email hello@saniservice.com) can help diagnose the problem and provide remediation services if necessary. They'll inspect for any water damage, clean the ductwork thoroughly, and ensure all seals are intact to prevent future issues.

In the meantime, you might want to run your ac on a higher fan speed setting which can sometimes help circulate air better and mask odors. However, this is just a temporary measure and shouldn’t replace professional cleaning.

To prevent such problems in the future, make sure to have regular maintenance checks done by certified technicians. This includes checking for any leaks or damages in the ductwork, ensuring proper insulation, and having a reliable dehumidification system to control humidity levels within your home.

Remember, maintaining good indoor air quality is crucial for health, especially during rainy seasons when such issues are more common. Taking proactive steps now can save you from bigger problems down the road.
