Is AC mold causing our stuffy noses?« Back to Previous Page

After the recent heatwave, we’ve had our air conditioner running almost non-stop. My bedroom has that faint, musty smell even after cleaning, and my kids have been complaining of a stuffy nose and coughing at night. Could this be related to the AC or mold building up in the system? What should I do to clean it properly and make sure it’s safe for us?

Is AC mold causing our stuffy noses?

Absolutely! The recent heatwave sure has been tough and your air conditioner (AC) running almost non-stop could be the culprit behind those musty smells, stuffy noses, and coughing. In Dubai, AC systems can indeed harbor molds that may not get fully eradicated just by simple cleaning.

Firstly, it's important to understand the regulations here in the UAE. The Environment Agency – Abu Dhabi (EAD) emphasizes the importance of regular maintenance for HVAC systems to ensure they operate efficiently and safely. Given your symptoms, it sounds like a professional inspection might be necessary to identify any hidden mold growth within the AC system.

To properly address this issue, start by shutting off the AC and opening windows if possible, to allow some fresh air in. Use a mixture of water and vinegar or baking soda for a DIY clean - mix 1 cup of white vinegar with 2 cups of warm water and spray it into the AC filter. For deeper cleaning, you might need to remove the evaporator coil and wash it outside. Make sure everything dries thoroughly before reinstalling.

However, if these steps don’t resolve the issue or if you notice visible mold growth, it’s highly advisable to call in a professional. In Dubai, companies like Saniservice can offer deep cleaning services for AC systems, ensuring all areas are properly sanitized and any potential mold is removed. They'll have the right tools and expertise to tackle even hard-to-reach spots.

Remember, your health is paramount. If symptoms persist after proper cleaning or if you're unsure about what to do, a visit to a healthcare provider might be necessary as well. Don’t hesitate to contact Saniservice at 800-MOLDS or email them at hello@saniservice.com for more guidance.

Taking these steps should help clear up your symptoms and ensure that the air in your home is safe and comfortable for you and your family during this hot weather.
