Mold chiller clean or replacement cost for villa AC?« Back to Previous Page

Good question, and this is a very common issue in Dubai's climate, especially in older villas in areas like Jumeirah. The "mold chiller" your technician mentioned is almost certainly your outdoor condensing unit, and the damp smell indicates a significant microbial growth problem inside the system, likely in the evaporator coil and drip pan.

A simple handyman clean is not sufficient and can even cause damage. They lack the specialized equipment, EPA-certified biocides, and knowledge of UAE's DWDM and DM regulations for safe chemical disposal. A proper hygienization involves dismantling the unit, steam cleaning, applying antimicrobial coatings, and fogging the ductwork.

For a 4-bed villa, expect a professional deep clean and hygienization to range from AED 1,500 to AED 3,500, depending on the system's size and contamination level. A full chiller replacement is a major capital expense and can range from AED 8,000 to over AED 20,000 for a quality unit.

Given the persistent smell, I strongly recommend a professional inspection first to assess the true extent of the mold growth before deciding on a clean or replace path. Our company uses borescopes to inspect inside the ductwork and units without invasive demolition.
