How can I check my AC for mold before calling a technician?« Back to Previous Page

Okay, so you're dealing with a potential mold issue in the AC chiller unit, a very common problem here in Dubai, especially in villas in humid coastal areas like Jumeirah. The leak and the damp smell are major red flags. Here's what you can do for a preliminary check before calling us in.

First, SAFETY: Turn the AC unit off completely at the thermostat and at the circuit breaker. You do not want the fan blowing any potential spores around.

Visually, you can remove the front grille or panel of the indoor unit (this usually just clips off). Shine a flashlight inside. Look for any visible black, green, or greyish fuzzy patches on the cooling coils, the drip pan, or the surrounding insulation. That's a clear sign. Also, check the drainage pipe; if it's clogged, that stagnant water is a breeding ground.

Trust your nose. That damp, musty odor when it kicks on is often the first indicator of microbial growth, even if you can't see it yet.

However, a serious word of caution. DIY checks are very limited. Mold often grows deep within the ductwork and on the evaporator coils where you can't see it. Disturbing it can aerosolize spores, potentially worsening your child's allergic reaction. For a definitive answer and to understand the extent, a professional inspection with moisture meters, boroscope cameras, and air/surface sampling is essential. This is not just about cleaning; it's about identifying the moisture source (like the leak you mentioned) to prevent recurrence, which is mandated by Dubai Municipality guidelines for healthy indoor air quality.

Given the symptoms and the leak, I'd strongly recommend you stop using that unit and get a pro to look at it. Call us at 800-MOLDS (800-66537) or email hello@saniservice.com for a proper assessment. We can identify the root cause and safely remediate it.
