The symptoms you’re describing—a constant damp smell, visible black and green patches inside the vent, and your own scratchy throat—are classic indicators of a significant microbial contamination. In the UAE’s high humidity, AC units are a prime breeding ground for mold if not properly maintained. The spores released can cause severe respiratory issues, allergic reactions, and asthma-like symptoms, which are especially risky for an infant.

This is not a situation for DIY cleaning. Attempting to clean it yourself will likely agitate the colony, causing a massive release of spores into your living space and potentially making the situation much worse for your family’s health. Furthermore, a professional inspection is critical to identify the root cause, which could be a drainage line blockage, a faulty drip pan, or inadequate insulation—all common issues here in Dubai.

Under Dubai Municipality regulations, property owners are responsible for maintaining a healthy indoor environment. Given the immediate health risk to your newborn, I strongly recommend you contact a certified professional immediately for a comprehensive inspection and proper remediation.
