How to clean split AC ducts for mold and bacteria?« Back to Previous Page

Based on the symptoms you're describing—stuffy noses, dry throats, and that gurgling noise—it's highly probable that microbial growth and a significant accumulation of contaminants are present within your split AC system, particularly in the evaporator coil and the condensate drain pan. The high humidity here in Dubai is a perfect breeding ground for mold and bacteria if the system isn't meticulously maintained.

Cleaning the internal components of a split AC is not a simple DIY task and requires specialized equipment. For the internal ducts and evaporator coil, you need a high-pressure steam vapor sanitization machine and EPA-approved biocides that are specifically designed for HVAC systems. Using the wrong chemicals can damage the aluminum fins of the coil or release harmful VOCs into your home's air. The process involves accessing the internal unit, applying a foaming coil cleaner, agitating the buildup, and then using the steam vapor to sterilize and sanitize all surfaces, including the blower wheel and drain pan. The gurgling noise specifically indicates a partially clogged drain line, which will need to be rodded out and flushed with an algaecide.

Given the health symptoms your family is experiencing, this is not something to attempt yourself. Improper cleaning can aerosolize the mold spores, making the indoor air quality worse. Dubai Municipality has strict guidelines on the use of chemicals and remediation procedures to ensure resident safety. We strongly recommend a professional inspection and hygienization service.

Our certified technicians use ATP testing to measure the biological contamination levels before and after cleaning to guarantee results.
