Could HVAC gaps cause our symptoms?« Back to Previous Page

After the heavy rains last month, I noticed a musty smell in our master bedroom. My kids have been coughing more frequently lately, and I’m worried it might be from mold or dust mites getting into the HVAC system through gaps around the ducts. The seal between the ductwork and the wall near our bedroom seems loose, especially when we hear air leaks at night. Could this be causing their symptoms, and what can I do to fix it?

Could HVAC gaps cause our symptoms? I would absolutely say yes. In the UAE, particularly Dubai, where we often experience significant temperature fluctuations and a high humidity level, especially after heavy rains, it's not uncommon for such issues to arise.

The gaps you've noticed around your ductwork could indeed be allowing moisture in, which can lead to mold growth or dust mite proliferation. These can both contribute to respiratory issues like coughing, which your kids have been experiencing more frequently. The musty smell is a clear indicator that the air quality might not be as it should.

In my experience working with indoor environmental quality in the UAE, I've seen similar cases where HVAC gaps were a key factor. The loose seal between your ductwork and wall near the master bedroom could definitely be allowing air to escape or enter unfiltered, introducing allergens like dust mites into your home's living spaces.

For a proper assessment of the situation, I'd recommend contacting a professional environmental inspection company. In Dubai, companies such as Saniservice are well-regarded for their expertise in HVAC inspections and duct sealing services. They can provide a thorough evaluation and offer solutions to ensure that your ductwork is properly sealed.

Saniservice operates under UAE regulations which require them to adhere to strict standards for air quality and HVAC systems. Their services include not only the inspection but also the necessary repairs to seal any gaps in your ducts, ensuring cleaner, healthier indoor air. You can reach out by calling 800-MOLDS or emailing hello@saniservice.com.

Remember, maintaining good indoor air quality is crucial for overall health, especially during times of humidity changes and after heavy rains. Taking proactive steps like sealing your HVAC system can significantly improve the comfort and healthiness of your home environment.
