Musty Smell & Weak Cooling? You Probably Need a Chemical Wash

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. Malaysiaโ€™s 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.

5 Signs Your Aircond Needs a Chemical Wash Right Now

You do not need to wait for a breakdown. These are the signs your unit is telling you it needs a proper deep clean.

1. Musty or Damp Smell When You Switch It On

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.

2. The Air Is Not as Cold as It Used to Be

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.

3. Water Is Dripping from the Indoor Unit

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.

4. Your TNB Bill Has Gone Up Without Explanation

A dirty aircond unit uses 15โ€“25% 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.

5. The Unit Has Not Had a Deep Clean in Over a Year

In Malaysia's climate, units running 8โ€“12 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.

How long does a chemical wash take?


Between 45 minutes and 1.5 hours per unit, depending on contamination level.
  • No deep clean in over 2 years โ†’ closer to 1.5 hours
  • Regular service history โ†’ 45โ€“60 minutes

What is the difference between a chemical wash and a normal service?


  • Normal service โ€” cleans filter and accessible surfaces (20โ€“30 min)
  • Chemical wash โ€” cleans evaporator coil, blower wheel, and drain pipe using chemical solution (45โ€“90 min). Removes mould, bacteria, and deep contamination that a normal service cannot reach.

Will the chemical wash damage my aircond?


No โ€” when done by trained technicians using the correct chemicals. We use alkalineโ€‘safe solutions for aluminium coil fins and plastic components. Damage only occurs with incorrect chemicals or rough handling. Our technicians are trained on the correct process for all major brands.

My unit still smells after a chemical wash. What happened?


This is rare but can happen if mould has penetrated deep into the coil over many years. In some cases, a second wash or a chemical overhaul (removing the indoor unit entirely) is needed.

WhatsApp us and describe the situation โ€” if the smell returns within the 30โ€‘day warranty period, we come back at no charge.

Do I need a chemical wash or a gas refill?


  • Musty smell + weak cooling โ†’ chemical wash first. Mould on the coil causes both.
  • No smell, only weak cooling โ†’ possible gas leak.
We check gas pressure as part of every chemical wash and top up 20% as standard โ€” so you often get both in one visit.

Do you service all aircond brands?


Yes โ€” all major brands sold in Malaysia.
Daikin, Panasonic, Mitsubishi Electric, York, LG, Samsung, Midea, Gree, Toshiba, Haier, and more. Our technicians carry brandโ€‘specific training and common parts.
