Most aircond problems that people think need a repair actually need a chemical wash. The musty smell, the weak cooling, the water dripping indoors โ these are almost always caused by contamination deep inside the unit, on the evaporator coil and blower wheel, where a standard filter clean cannot reach.
ACFix has been carrying out chemical washes across Kuala Lumpur and Selangor since 2012. Malaysiaโs humidity means mould grows inside aircond units faster than in cooler climates โ and once it is on the coil, the only way to remove it properly is a chemical wash. We use safe, professional-grade cleaning solutions, and every chemical wash includes a 20% free gas top-up and a 30-day workmanship warranty.
๐ก Simple rule: If your unit smells musty, cools weakly, or has not had a deep clean in over a year โ you need a chemical wash, not a normal service.

This is mould growing on the evaporator coil โ in the dark, constantly moist interior of the unit. A normal service does not reach the coil. The smell will return within days of a standard filter clean because the source is never touched. A chemical wash removes it from the root.
Dirt and mould on the evaporator coil act like insulation โ they stop the coil from absorbing heat from your room. The unit runs, the compressor works, but the air comes out warm or mildly cool. Many homeowners think they need a gas refill. Usually, they need a chemical wash first. A clean coil can restore full cooling without touching the gas.
Water leaks are almost always caused by a blocked drain pipe. In Malaysia's humidity, algae and sludge build up inside the drain line and block the flow โ water then backs up and drips from the unit. A chemical wash flushes the drain completely. If the leak is more serious, see our aircon water leak repair page.
A dirty aircond unit uses 15โ25% more electricity than a clean one. The compressor has to work harder to push air through a contaminated coil โ which drives up your electricity consumption. If your TNB bill has been creeping up, your aircond is a likely cause.
In Malaysia's climate, units running 8โ12 hours a day accumulate coil contamination fast. If your unit has not had a chemical wash in over 12 months โ or you have no idea when the last one was โ book one. You cannot see the inside of the coil from the outside, and by the time the smell or cooling problem appears, the contamination is already severe.
