Is AC leak causing mold and health issues emergency?« Back to Previous Page

Our AC unit in the bedroom has been leaking a bit for the last couple of weeks, and now I’m seeing small black spots spreading on the wall behind the curtain. My husband has had a constant stuffy nose and a cough that just won’t go away, and I’m starting to worry. Is this something we need to get an emergency specialist for this weekend, or can it wait until next week for our building’s maintenance to take a look?

The black spots and persistent respiratory symptoms are strongly indicative of a mould issue, and it should be addressed promptly. The AC leak provides the constant moisture that mould needs to thrive, especially in Dubai's climate where high humidity can accelerate its growth inside our homes.

This is not typically a midnight emergency requiring a weekend call-out, but it is a serious health concern that should not be postponed for a regular building maintenance schedule next week. Your husband's ongoing cough and congestion are common reactions to mould exposure. For individuals with asthma or other respiratory sensitivities, prolonged exposure can lead to more significant health complications.

Your immediate action should be to stop using that specific AC unit to prevent it from spreading more moisture and mould spores into the air. Keep the bedroom door closed to contain the area. Building maintenance can fix the leak, but they are unlikely to handle the mould remediation itself. The leak repair is the first step, but the mould growth on your wall requires proper assessment and removal.

For a situation like this, a professional inspection is recommended to determine the extent of the growth, even behind the wall. Proper remediation involves containing the area, safely removing the contaminated materials, and HEPA vacuuming to clear spores from the air. Simply wiping the spots away is insufficient and can aggravate the problem. Once the source of moisture is fixed and the mould is professionally remediated, your indoor air quality should improve, and the health symptoms will likely subside.
