The indoor unit stays on the wall while a cleaning solution is applied to the evaporator coil, blower wheel and drain parts, then flushed out with a wash bag to catch the run-off. It suits units that still cool weakly after normal servicing, smell musty at start-up, show light mould on the fins, or leak again soon after a drain flush. Price is from S$80 per unit; the final fixed quote depends on unit type and condition and is confirmed before work starts. ### What's included - Evaporator coil, blower wheel and drain pan cleaned with solution and flushed - Drain line flushed; filters washed - Walls and floor covered; area cleaned after - PCB protected during the wash; each unit test-run - 90-day workmanship warranty ![Evaporator coil being rinsed during a chemical wash, dirty run-off caught in the wash bag](/images/content/close-up-of-evaporator-coil-fins-being-rinsed-duri.webp) ## Why Does Cooling Stay Weak After Normal Servicing? Has your aircon been serviced, yet the room still never feels properly cold? We hear this a lot from flat owners with two to four wall-mounted units. Often the answer is an aircon chemical wash, not another general service. General servicing is the routine part of looking after your aircon. It keeps the filter clean and the drain clear. What it cannot do is wash out the dirt that builds up deeper inside the **fan coil unit**, on the evaporator coil fins and on the curved blades of the blower wheel. Singapore’s air stays humid all year. According to the Meteorological Service Singapore, mean annual relative humidity sits at roughly 82%. Dust mixes with that moisture and forms a sticky layer, which over months turns into **mould and biofilm**. Here’s what that layer does to your room: - Air struggles to pass through a coated coil, so the unit can’t pull heat out of the room. - A dirty blower wheel moves less air, so the cool air never reaches your bed or sofa. - The compressor works harder for the same result. Singapore servicing firm MET estimates that a dirty coil costs roughly 10 to 15 percent in efficiency. You hear the unit running, but the room never feels properly cold. That is the point where a chemical wash makes sense. Many of the units we see in older Jurong East estates such as Yuhua and Teban Gardens have had years of general servicing but never a deep clean. ## What Happens During an Aircon Chemical Wash? We start by checking the unit and confirming the fixed price with you. Then we prepare the room. Covers go over the floor, bed and furniture, and a **wash bag** is fitted under the indoor unit to catch the run-off. 1. The front cover and filters come off, and the filters are washed. 2. The **PCB control board** is protected so no liquid reaches it. 3. An **alkaline coil cleaner** is applied to the evaporator coil and left to work on the grime. 4. The coil, **blower wheel** and **drain pan** are flushed with water until it runs clean. 5. The **condensate drain line** is flushed so water flows freely to the outside. 6. The unit is put back together and an **airflow test** checks cooling and air output. Helpling’s Singapore guide puts a typical chemical wash at about 1 to 2 hours per unit. If you have three units, set aside a good part of the day. Most customers are surprised by the colour of the water in the wash bag. We are happy to show you. ## Common Problems a Chemical Wash Solves ### Musty smell when the aircon starts That damp, sour smell usually comes from mould on the coil and blower wheel. Singapore aircon specialists Airple point out that it is almost never just a dirty filter, since the mould sits on the coil, blower wheel or drain pan. A wash removes it at the source rather than masking it. ### Room takes a long time to cool A coated coil cannot transfer heat well. Servicing firm Prima Services describes that layer of dust and grime as acting like insulation on the coil surface. Once it is clean, most **wall-mounted split units** cool noticeably faster. ### Water dripping again soon after a drain flush If sludge keeps building in the drain pan, a simple flush only buys a few weeks. Trouble starts when the drain restricts or dust sits on wet surfaces, as Singapore’s EZ Aircon explains. Washing the coil and pan together clears the source. ### Visible black spots on the fins or blower Light spotting can be washed off. Heavy black mould blowing out of the vents usually needs a chemical overhaul [/aircon-chemical-overhaul/ →](/aircon-chemical-overhaul/) instead. Not sure which one you have? Snap a photo of the fins with your phone torch on and send it over. ## Chemical Wash or Something Else? | Situation | Usually the right job | | --- | --- | | Unit serviced in the last 3 to 4 months, cooling fine | General servicing on schedule | | Weak cooling or mild smell after servicing | Chemical wash | | Strong sour smell, black mould, jelly sludge | Chemical overhaul | | Cooling fades over months, ice on the pipe | Gas top-up with leak check | | Unit dripping onto the wall or bed | Water leak repair | Many Singapore servicers, including Billy Aircon and City Cooling Engineering, suggest a chemical wash every 6 to 12 months for HDB homes. Bedrooms that run 10 to 12 hours a night sit at the shorter end of that range. If you are unsure which applies, send a short video of the unit running. We will tell you honestly, including when a wash is not needed yet. ## Keeping Units Clean After the Wash A wash resets the unit, but dust starts collecting again straight away. Washing the filters every 2 to 4 weeks and booking general aircon servicing [/ →](/) every 3 to 4 months keeps the coil cleaner for longer. Here’s one more habit that costs nothing. Several Singapore mould-removal specialists, including Pico X, suggest switching to fan-only mode for 15 to 20 minutes before you turn the unit off. The coil dries instead of sitting wet overnight.

Got questions? ## Chemical Wash FAQs ### How much is an aircon chemical wash in Jurong? From S$80 per unit. The final price depends on the unit type and its condition, and you get a fixed quote before any work starts. There is no callout fee for Jurong. ### What is the difference between general servicing and a chemical wash? General servicing washes the filter, checks the coil and flushes the drain. A chemical wash applies a cleaning solution to the evaporator coil, blower wheel and drain parts, then flushes it all out. It removes the grime that general servicing cannot reach, which is why cooling often improves after a wash. ### How do I know my aircon needs a chemical wash? Common signs are cooling that stays weak right after servicing, a musty smell when the unit starts, light mould on the fins or blower, and a leak that comes back soon after a drain flush. If you are not sure, send us a photo on WhatsApp. ### Do I need a chemical wash or a chemical overhaul? A chemical wash suits weak cooling or mild smells and keeps the unit on the wall. An overhaul dismantles the unit and suits heavy mould, strong sour smells, jelly sludge in the drain pan or units with no deep clean for over a year. ### How often should I do a chemical wash? Most homes with daily use do one about once a year, with general servicing every 3 to 4 months in between. Bedrooms used every night, or units near cooking areas, may need it sooner. ### Is a chemical wash safe for inverter units? Yes. We protect the PCB control board before applying any solution and rinse the coil thoroughly. Inverter and non-inverter units are both washed the same careful way. ### Will the chemical wash make a mess? We cover the floor, bed and nearby furniture, fit a wash bag to catch the run-off and clean up afterwards. Please clear small items from under the unit before we arrive. ### Is there a warranty on a chemical wash? Yes. All work carries a 90-day workmanship warranty. If the same fault comes back within 90 days, we return and fix it at no extra charge. ### Do you do chemical washes on Sundays and evenings? Yes. We are open Monday to Saturday 9:00 AM to 9:00 PM and Sunday 9:00 AM to 8:00 PM. Same-day slots are offered subject to availability. ### Still have a question?
