An aircon chemical wash — also called aircon chemical cleaning in Singapore — deep-cleans the internal coil, fan, and drainage system of your aircon unit without dismantling it.
Recommended when your unit is not cooling well, has a musty smell, or has not had a chemical clean in over 12 months. We service wall-mounted and ceiling cassette units across HDB, condo, and small commercial properties.
An aircon chemical wash is a non-dismantle deep-cleaning service. Specifically, the technician applies chemical cleaning agents to the indoor unit’s evaporator coil, fan blades, and drainage tray, without removing the unit from the wall.
As a result, it removes dust, mould, and biological build-up that routine servicing cannot reach. In turn, this restores airflow, improves cooling performance, and eliminates musty odours.
However, a chemical wash is not the same as a chemical overhaul. The key difference is simple: a chemical wash keeps the unit mounted, whereas a chemical overhaul requires full disassembly.
Each chemical wash visit includes:
The unit stays on the wall throughout. No dismantling, no reassembly risk.
If the unit is found to be heavily clogged during the service, the technician will advise whether a chemical overhaul is needed.
Book a chemical wash if your unit shows any of these:
If your unit is leaking water, making loud noise, or not switching on at all, you may need a repair or chemical overhaul instead.
All prices are confirmed before work begins. No hidden charges.

Is a Chemical Wash Right for Your Aircon? Quick SpecsUse this quick spec sheet to check if a chemical wash fits your unit and budget. If it doesn’t, then we’ll recommend general servicing or a chemical overhaul instead.
If the technician finds heavier build-up during the wash, then they will flag it on the spot and, if needed, recommend an overhaul. As a result, no second visit is needed.
Wall-mounted units are the most common type we service. In addition, we work within building access requirements and keep all work areas clean throughout.
We service multiple units across a property in a single visit. However, ducted or concealed systems are assessed before booking, so we can confirm a chemical wash is appropriate.
Ceiling cassette units in offices benefit most from a chemical wash when airflow or cooling drops. However, cassette units use a different cleaning process from wall-mounted, so see our ceiling cassette aircon cleaning service for scope and pricing. In addition, contract maintenance plans are available for offices with 4 or more units.
SACES has been servicing aircon units across Singapore for over 30 years. As a result, our technicians are licensed, experienced on all major brands, and assigned to your property consistently.
Real feedback from Singapore homeowners and businesses.
An aircon chemical wash is a professional deep-cleaning service where the unit casing is opened to access the evaporator coil, fan blades, and drainage tray. Next, a chemical solution is applied to remove mould, dust, and biological build-up. Throughout the process, the unit stays mounted on the wall. Finally, we reassemble the casing clean at the end.
Aircon chemical wash (also called aircon chemical cleaning) costs $160 per wall-mounted unit. However, ceiling cassette units cost $370 per unit, because cleaning a cassette involves more dismantling time and access difficulty. In all cases, the price is confirmed in writing before work starts.
Every 12 months for regular home use. However, units in dusty environments or under heavy use may need it more often, roughly every 6 to 9 months.
A chemical wash is non-dismantle, so the unit stays on the wall. A chemical overhaul, by contrast, involves full disassembly for a deeper clean. Therefore, an overhaul is recommended for heavily clogged, leaking, or long-neglected units.
Yes, if poor cooling is caused by build-up on the coil or blocked airflow. However, if cooling does not improve after the wash, then the technician will advise on the next step, such as a gas top-up or repair.
Yes. SACES covers all HDB towns, condominiums, landed properties, and commercial spaces island-wide. In short, that means North, South, East, West, and Central Singapore.
Yes. In Singapore, the two terms describe the same non-dismantle deep cleaning service. In fact, contractors use both interchangeably, and the price, scope, and chemicals used are identical. The service to actually differentiate against, however, is a chemical overhaul, which requires full disassembly.
