AC leak causing mold and health issues: fix ourselves first?« Back to Previous Page

Based on your description, this is a serious situation that requires immediate attention. The constant AC leak is providing the perfect moisture source for mold growth, and the symptoms you're describing (stuffy nose, headaches) are classic indicators of mold exposure.

While you can address the surface issue, a professional inspection is strongly advised for a case like this. Here's why and what you can do first.

The black mold you see is likely just the surface manifestation. The leak has probably saturated the wall's internal structure (drywall/plasterboard), where the main colony is thriving. Simply wiping the visible patch is a temporary fix at best.

For a DIY first step, you MUST address the water source. Turn off the AC unit and call an HVAC specialist to fix the leak permanently. This is non-negotiable. Once the leak is stopped, you can carefully clean the visible mold on non-porous surfaces with a solution of detergent and water. However, do NOT attempt to clean it with bleach, as this can release more spores and is ineffective on porous materials.

Crucially, if the mold has penetrated the wall, which is highly likely, the affected drywall and insulation will need to be removed and replaced by professionals to prevent regrowth and ensure all mycotoxins are eradicated. Given the health symptoms and the extent of the moisture problem, a full assessment is needed. We use thermal imaging cameras and moisture meters to find the full extent of the damage hidden behind the walls.
