Moldy AC smell: DIY clean or call Dubai professinal?« Back to Previous Page

A faint moldy smell and visible black spots in the drip tray indicate active microbial growth, a common issue in Dubai due to high humidity and year-round AC use. This is likely aggravating your husband's allergies.

For a minor surface issue, a DIY clean with a diluted white vinegar solution can be effective. Turn off the unit's power, remove accessible parts, and scrub the tray and coils. However, if the smell persists or the growth is extensive, the contamination is probably deep within the unit or ductwork, which requires professional disassembly and cleaning.

Given the symptoms have lasted for months, a professional inspection is strongly recommended. They use specialized tools to access the entire system and apply EPA-approved biocides to treat growth at the source. The cost for this service is variable, as it depends entirely on the AC unit type (central, split), the extent of contamination, and the size of your apartment. For an accurate assessment and quote, you would need to request an on-site inspection from a certified provider. Look for companies that offer before-and-after testing to verify the results, not just a visual clean.
