How to test AC for mold causing sickness in Dubai?« Back to Previous Page

The AC in our bedroom seems to blow out a damp, earthy smell whenever it kicks on, and for the last few weeks, both my wife and I have been waking up with stuffy heads and sore throats. I’ve checked the vents but can’t see anything obvious. We’re in a villa in Mirdif that’s a few years old. What’s the most reliable way to get the air and the AC unit itself tested for mold to see if that’s what’s making us sick?

Based on your symptoms and the description of a damp, earthy smell, your AC unit is a prime suspect for microbial contamination, a common issue in Dubai's humid climate. The most reliable method is a professional indoor air quality (IAQ) assessment, which we perform for clients in Mirdif and across the UAE.

A proper test is not just a swab. We conduct a comprehensive inspection that includes:

1. Visual Inspection: A thorough examination of the AC evaporator coils, drip pans, ductwork, and plenums using specialized tools, as contamination is often not visible from the vent alone.
2. Air Sampling: We collect non-viable air samples from your bedroom and a control location (like outside) to quantify the spore count and compare it to the baseline outdoor level, as per best practices.
3. Surface Sampling: Tape-lift or swab samples are taken directly from inside the AC unit to identify the specific genus of mold present (e.g., Aspergillus, Penicillium, Cladosporium).

This combination of data tells us not just if there is mold, but the type and concentration, which is critical for determining the health risk and the appropriate remediation protocol. DIY test kits are highly unreliable and cannot provide this level of analysis.

Given that you are already experiencing physical symptoms, we strongly advise against attempting to clean the unit yourself, as this can aerosolize spores and exacerbate the problem. Professional assessment and remediation are essential.

For a definitive diagnosis and to get your villa's air quality back to a healthy state, please call our team at 800-MOLDS or email us at hello@saniservice.com to schedule an inspection.
