Aircon Chemical Wash in Singapore
From $110 per unit. In-place chemical cleaning that clears mould, bacteria, and stubborn dirt — restoring cooling and removing musty smells.
What is an aircon chemical wash?
Chemical wash is a deeper clean than normal servicing. The technician uses specialised chemical solutions to break down and flush out dirt, mould, and bacteria from the evaporator coils, drainage tray, and other internal surfaces — areas that filter-level cleaning cannot reach.
The major components stay mounted in place during a chemical wash, which keeps it faster and more affordable than a chemical overhaul. It is the right choice when your aircon has started to smell, drip, or cool less effectively despite regular servicing — but the unit is not so neglected that it needs full disassembly.
When you need a chemical wash
Any one of these is a sign the indoor unit has dirt built up beyond what normal servicing removes.
Musty or sour smell
A sour, damp odour every time the aircon runs is the clearest sign of mould on the evaporator coil.
Weak cooling despite regular servicing
When normal servicing no longer restores cooling, dirt has built up deeper than filter-level cleaning can reach.
Visible mould on the fan coil
Black or dark spots on the visible fan coil surface mean mould has spread across the unit interior.
Water dripping from the indoor unit
A clogged drainage path forces condensation to overflow from the fascia instead of draining away.
Over a year since the last deep clean
Even without symptoms, units used daily in Singapore’s humidity benefit from a deep clean every 1–2 years.
Chemical wash vs chemical overhaul
Both are deep cleans — the difference is how far we strip the unit down.
