What can we do about dusty AC causing allergies?« Back to Previous Page

The AC in my apartment seems to be circulating some kind of dust that's making everyone in the house sneeze more than usual. We’ve had the unit cleaned a few months ago, but the symptoms started up again last week after a particularly hot day. My husband is already complaining about his asthma acting up too. Is there anything we can do besides just running the AC less?

Cleaning allergies caused by dusty AC units can be a bit of a challenge especially during the hot and humid weather like we experience in Dubai. The symptoms you've described are quite common and could indicate that there's more than just dust circulating in your air conditioning system.

First off, it’s vital to understand that maintaining an indoor environment free from allergens is crucial for those who suffer from allergies or asthma. In the UAE, such concerns might not be covered under specific regulations but it's a good practice to keep your living spaces clean and healthy.

The first step would be to have your air conditioning unit professionally inspected by a certified HVAC technician. This should include a thorough cleaning of all components including the evaporator coils, filters, ducts, and fans. In Dubai, it’s recommended to do this service at least twice a year, with additional maintenance during times when you notice increased symptoms.

In addition to professional servicing, there are some steps you can take yourself:
1. Replace or clean your air conditioning filters regularly. This is crucial as dirty filters can harbor dust and mold spores.
2. Ensure that the condensate drain lines from your AC unit are clear of blockages. A clogged line can lead to water pooling and promote mold growth.
3. Consider using an air purifier with a HEPA filter in areas where allergy symptoms are most noticeable, like bedrooms.

Another tip would be to keep humidity levels low by regularly running your dehumidifier or AC. High humidity levels (above 60%) provide the perfect environment for dust mites and mold to thrive. In Dubai, maintaining an indoor relative humidity between 35% - 45% is ideal according to local guidelines.

Lastly, if you notice any musty odors or visible signs of mold like black spots on walls or ceilings, it’s essential to address these promptly. Mold remediation should be handled by a professional as improper handling can spread spores and exacerbate allergy symptoms.

Remember, running your AC less is not always the best solution - keeping indoor air cool and clean is key. If you find that despite all efforts, you’re still experiencing severe symptoms, it might be time to seek help from an environmental inspection company like us at Saniservice.

In summary, tackling dusty AC units requires a combination of professional service and personal care. By implementing these steps, you should see significant improvement in your living environment and reduced allergy symptoms.
