Which path fits your situation
What the cost of aircon chemical wash in Singapore covers
The cost of aircon chemical wash in Singapore reflects a full deep cleaning of the unit - not just a surface wipe. Technicians dismantle the air conditioning unit, flush the evaporator coils and drainage, and treat the mould and bacteria a standard service leaves behind. For older air conditioners with weak airflow or a sour smell, a chemical wash is what restores cooling performance and stops the gradual rise in your electricity bill.
Aircon chemical overhaul Singapore - when a wash isn't enough
An aircon chemical overhaul Singapore homeowners book goes deeper than a wash: the fan-coil is fully dismantled - motor, blower and drain tray out - to clear mould and blockage a surface chemical wash can't reach. Rough guide: a chemical wash runs from about S$90 per unit, while a full chemical overhaul runs around S$280 depending on unit size and how clogged it is. Choose the overhaul when cooling stays weak after a normal wash, the sour smell returns within weeks, or the unit hasn't been serviced in over a year.
