Ever switched on your aircon and caught a musty whiff before the cool air shows up? That’s the moment most Jurong homes start looking for an aircon chemical wash. An aircon chemical wash is a deep clean of the indoor unit while it stays on the wall. Here’s how our technician does it: 1. Fit a **catch bag** under the **wall-mounted split unit**. 2. Apply an **alkaline coil cleaner** to the **evaporator coil** and **blower wheel**. 3. Let the cleaner work into the dirt. 4. Flush everything out with water. 5. Flush the **drain pan** and **condensate drain line** last, so the loosened grime leaves the unit instead of blocking it. General aircon servicing [/ →](/) cleans the filter and the front of the coil. It can’t reach the dust packed deep between the fins, or the film of **mould** that grows on the blower wheel in Singapore’s humidity. That build-up makes a unit blow weaker, take longer to cool a room and smell musty at start-up. | Job | What gets cleaned | Price | | --- | --- | --- | | General servicing | Filter, front of the coil, drain line flush | S$50 for 1 unit, S$70 for 3 | | Chemical wash | Coil, blower wheel, drain pan and drain line, unit stays on the wall | From S$80 per unit | | Chemical overhaul | Unit taken apart, every part cleaned one by one | S$130 to S$180 per unit | Industry price guides, such as Billy Aircon’s 2026 page, put a non-dismantle wash at about 45 to 60 minutes per wall-mounted unit. Plan on roughly that per unit, so a 3-unit flat fits into a morning or an afternoon. A chemical wash costs from S$80 per unit, with a fixed quote before work starts and no callout fee anywhere in Jurong. ## When does a Jurong unit need a chemical wash? Most homes in Jurong run their aircon almost every day. In a typical **HDB flat**, the bedroom units run every night and the living room unit runs most evenings. After a year or so of that, general servicing alone stops bringing cooling back. Book a wash when you notice: - Cooling is still weak even after normal servicing - A musty or damp smell for the first few minutes after switching on - Dark spots of mould on the fins or the blower wheel - A leak that comes back soon after a drain flush Helpling’s guide suggests a chemical wash every 6 months for HDB bedroom units that run 10 to 12 hours a day. Living room units that run fewer hours usually cope with every 6 to 12 months. Energy is another reason not to wait. Coogle Aircon, citing the Energy Market Authority’s 2022 statistics, says aircon typically makes up 40 to 60% of a 4-room HDB household’s electricity use. A clogged coil makes the compressor work harder, and you pay for that on the bill. We see this often in older Jurong East estates such as **Yuhua** and **Teban Gardens**, and in newer BTO flats that are due for their first deep clean. ## Common problems a chemical wash solves ### Weak airflow and slow cooling Dust and grease clog the coil fins, so less air passes through and less heat is removed. After a wash, our **airflow test** usually shows a clear difference in outlet temperature and fan strength. You can check it yourself too. Hold your hand at the vent before and after, and you’ll feel the difference. ### Musty smell at start-up The smell comes from mould and bacteria on the wet coil and blower. Flushing them out with solution removes the source, which a filter clean can’t do. ### Repeat leaks after servicing Slime in the drain pan breaks off and blocks the drain line again. A wash clears the pan properly, then we flush the line. A clear drain matters for more than leaks. The National Environment Agency (NEA) advises against placing trays or containers under an aircon unit, because standing water is a breeding spot for Aedes mosquitoes. ### Uneven cooling on multi-split systems On an **inverter system** such as a **multi-split System 3**, one dirty fan coil can cool poorly while the others are fine. We wash and test each fan coil separately. ## What affects the price of a chemical wash? The starting price is S$80 per unit. The final quote depends on three things: - The unit type and size - How dirty it is - Whether the unit is easy to reach For a sense of the wider market, Helpling’s guide shows chemical washes at around S$80 to S$120 per unit in Singapore, and full chemical overhauls at S$150 to S$250. So S$80 sits at the low end of that range. If we find black mould, sludge or a unit that hasn’t been cleaned in years, we’ll tell you an overhaul fits better and quote that instead, before any work starts. We never switch jobs halfway without your say. Not sure which job you need?

Teban Gardens Got Questions? ## Chemical Wash questions from Jurong customers ### How much is an aircon chemical wash in Jurong? A chemical wash starts from S$80 per unit. The final price depends on the unit type and condition, and you get a fixed quote before work starts. There is no callout fee. ### What is the difference between a chemical wash and general servicing? General servicing cleans the filter, checks and wipes the coil and flushes the drain. A chemical wash applies a cleaning solution deep into the evaporator coil and blower wheel and flushes it out, which removes dirt and mould that servicing cannot reach. ### Do I need a chemical wash or a chemical overhaul? A wash suits weak cooling and mild smells with the unit on the wall. An overhaul at S$130 to S$180 per unit dismantles the unit for heavy mould, black bits blowing out or sludge in the drain pan. ### How often should I chemical wash my aircon? For units used daily in Singapore, about once a year is common, alongside general servicing every 3 to 4 months. Bedroom units that run every night may need it sooner. ### How long does a chemical wash take? Usually about 45 minutes to an hour per unit, depending on how dirty the coil and blower are. ### Is a chemical wash safe for inverter aircons? Yes, when done properly. The technician protects the electrical parts and uses a solution suited to aircon coils. We wash inverter and non-inverter units of all common brands. ### Will the chemical wash be messy? We fit a catch bag under the unit and cover furniture before starting, then clean up after. Clear the area directly below the unit if you can. ### My aircon started leaking after a chemical wash elsewhere. Why? Loosened dirt can block the drain line if it is not flushed after the wash. We flush the drain pan and drain line as part of every wash, and the 90-day warranty covers our work. ### When does a new BTO flat need its first chemical wash? Often around one to two years after move-in, depending on how many hours the units run each day. ### Do you wash aircons in older Jurong East estates? Yes. We do many chemical washes in Yuhua, Teban Gardens, Toh Guan and Pandan Gardens, where units are often past their first deep clean. ### Still have a question?
