AC mold and poor cooling: urgent fix needed?« Back to Previous Page

The AC in my apartment seems to be constantly running but not cooling properly, and I've started noticing small black spots along the edges of the ceiling in my bedroom in Jumeirah Village Circle. It's been getting worse over the past couple of weeks since that last humid spell. With the summer heat coming, is this something I need to drop everything and call a professional for immediately, or can it wait a few days?

Based on your description, this is a situation that warrants prompt professional attention. The combination of poor AC cooling, high ambient humidity typical of the UAE, and visible black spots is a classic indicator of a mold issue originating from your air conditioning system.

The constant running without proper cooling strongly suggests a problem like a clogged drain pan or a blocked condensate drain line. When this happens, the excess moisture has nowhere to go and accumulates inside the AC unit and the surrounding ductwork, creating the perfect breeding ground for mold. The spores are then blown throughout your apartment, settling and growing on surfaces like your ceiling.

In the humid climate of JVC, mold can proliferate rapidly, as you've observed over the past few weeks. This isn't just a comfort issue; it's a potential health and property issue. Exposure to certain types of mold can cause allergic reactions and respiratory problems.

For a case like this, a DIY approach is not recommended. A professional inspection is crucial to identify the exact species of mold, the extent of the contamination within the AC system itself (which you can't see), and the correct remediation protocol. We use specialized equipment like borescopes to inspect inside ductwork and moisture meters to find hidden dampness.

I would advise you to schedule an inspection within the next few days, especially with summer intensifying. Please call our team at 800-MOLDS (800-66537) or email hello@saniservice.com to have a certified specialist assess the situation. Addressing the root cause now will restore your cooling efficiency and ensure your indoor air is safe.
