Are high humidity and mold causing my AC issues?« Back to Previous Page

Yes, absolutely. The symptoms you're describing—the AC running non-stop, a heavy/damp feel, scratchy throat, morning congestion, and those black spots—are classic indicators of a compromised indoor environment, specifically high relative humidity leading to mold growth. Here’s a breakdown from a professional standpoint.

Your AC is designed to cool and dehumidify. When it runs constantly but can't achieve a comfortable feel, it's a major red flag. The most common culprits here in Dubai are an oversized AC unit (so it cools too quickly without adequate runtime to remove moisture) or a system that is low on refrigerant or has a failing compressor, severely crippling its latent cooling (dehumidification) capacity.

The health effects and mold growth confirm the humidity is consistently above 60-65%. The UAE's regulatory guidelines, like the Dubai Green Building Regulations, emphasize maintaining indoor relative humidity between 40-60% for precisely these health and structural reasons.

The black spots in your wardrobe are almost certainly mold, which thrives in these damp, stagnant conditions.

To fix this without a full overhaul, start with these steps:
1. Get a digital hygrometer to confirm the humidity levels in each room.
2. Ensure all bathroom exhaust fans are working and used during/after showers.
3. Check that your AC drain line is not clogged; a blocked line can cause moisture to back up into the system and ductwork.

However, given the visible mold and health symptoms, this has likely progressed beyond a simple DIY fix. Mold in the air system can be redistributing spores throughout the villa. A professional inspection is crucial to assess the AC's performance, check for hidden mold growth within the ductwork or behind walls, and prescribe the correct remediation protocol.
