| Full-Dismantle Chemical Overhaul | S$130 to $180 per unit |
What Is an Aircon Chemical Wash?
An aircon chemical wash goes far beyond standard servicing. While regular aircon servicing cleans the surface-level dust and debris, a chemical wash uses a specialised alkaline detergent to dissolve stubborn grime, mould colonies, and bacteria that have built up deep inside the evaporator coils and blower fan.
This deep clean is especially important in Singapore’s humid climate, where mould and bacteria thrive inside aircon units - causing musty smells, reduced cooling performance, and potential health issues for your family.
Non-Dismantle vs Full-Dismantle: Which Do You Need?
Non-Dismantle Chemical Wash (S$80–$100/unit)
Best for units that have been regularly serviced but need a deeper clean. The technician applies the chemical solution directly to the evaporator coils and blower fan without removing them from the wall. This is faster and more affordable.
Recommended when:
- Your unit has been serviced regularly but still smells
- Cooling performance has dropped slightly
- It has been 6-12 months since the last chemical wash
Full-Dismantle Chemical Overhaul (S$130–$180/unit)
For heavily soiled units that have not been maintained in over a year. The technician completely dismantles the fan coil unit, removing the blower fan, evaporator coil, and drainage pan for individual soaking and cleaning. This is the most thorough clean possible.
Recommended when:
- Your unit has not been serviced in over a year
- There is visible mould or heavy grime
- The unit produces a strong unpleasant smell
- Cooling is significantly reduced despite gas levels being normal
Benefits of Chemical Wash
- Kills 99.9% of bacteria and mould - Our germicidal detergent eliminates harmful microorganisms, improving indoor air quality.
- Restores cooling efficiency - Clean coils transfer heat more effectively, so your aircon cools faster using less energy.
- Eliminates bad odours - That musty smell is caused by mould and bacteria. Chemical wash removes the source, not just masks it.
- Extends unit lifespan - Removing corrosive build-up from coils and the drainage system prevents premature component failure.
- Reduces electricity bills - A clean aircon does not have to work as hard, potentially saving 10-20% on energy costs.
Our Chemical Wash Process
Our technicians follow a precise process developed over 20+ years:
- Initial inspection - We assess the level of build-up and recommend the appropriate wash type.
- Protective setup - Work area is covered with protective sheets to prevent chemical splashes on your walls and furniture.
- Chemical application - Specialised alkaline solution is applied to the evaporator coils and blower fan. For overhauls, components are dismantled and soaked.
- Deep rinse - All components are thoroughly rinsed with clean water to remove all chemical residue.
- Reassembly and testing - The unit is reassembled, powered on, and tested for cooling performance and proper drainage.
- Quality check - We verify the unit is cooling correctly and there are no water leaks before leaving.

Chemical Wash FAQ
Normal servicing involves basic filter cleaning and drainage flushing. Chemical wash is a deep clean using specialised detergent that removes stubborn grime, mould, and bacteria from the evaporator coils and blower fan. We recommend chemical wash if your unit has not been serviced for over 6 months.
If your unit has been regularly serviced but still smells or does not cool well, a non-dismantle chemical wash is usually sufficient. If the unit has not been serviced in over a year or has severe build-up, a full-dismantle chemical overhaul is recommended.
A non-dismantle chemical wash takes about 45-60 minutes per unit. A full-dismantle chemical overhaul takes 1.5-2 hours per unit.
Yes. Our technicians use industry-approved alkaline solutions that are safe for all major aircon brands. The chemical is thoroughly rinsed after application.
For most homes, once a year is sufficient if you maintain regular 3-4 monthly servicing. If you have not serviced your unit in a long time, start with a chemical wash then follow up with regular servicing.
