Signs Your Aircon Needs a Chemical Wash
If your aircon shows any of these six symptoms, regular servicing won't fix it. A chemical wash is the right call.
Weak cooling
You just serviced it, but the room still feels warm.
Musty smell
A sour or mouldy odour hits you every time the unit switches on.
Water dripping inside
Sludge has blocked the drain pan or condensate pipe.
Ice on the coil
Visible ice on the evaporator means airflow is badly restricted.
Visible black mould
Black colonies or yellow slime on the fins once you pop the cover.
Higher electricity bill
Dirty coils force the compressor to work overtime.
Three Tiers, Fixed Pricing
From routine maintenance to full restoration. Same hospital-grade chemicals on every tier.
Commercial Chemical Wash
Chemical wash for commercial cassette, ducted, and ceiling-concealed units. For offices, F&B outlets, and retail. Quoted on-site with volume discounts for 5+ units.
