When you need it

Four signs it's time.

Regular service handles most maintenance. Chemical wash steps in when the biofilm has gone deep.

Cooling is weak even after general service

If a regular clean ($90-130) doesn't restore the airflow + cooling, the biofilm has soaked too deep into the coil fins. Chemical wash flushes it out.

Musty / sour smell when AC starts

Bacterial + fungal growth in the wet coil + drain pan. Air-freshener won't fix it — the source has to be physically removed. Chemical wash kills + flushes the colony.

Aircon hasn't been serviced in 12+ months

Singapore humidity means biofilm accumulation is fast — quarterly service is the spec. Past 12 months without one, the coil is usually past simple-clean territory.

Electricity bill creeping up

Clogged coil = compressor runs longer = bill higher. Chemical-washed units typically run 15-20% more efficiently — pays for itself over 12-18 months.

On-site protocol

5 steps · 2-3 hours per unit.

01
Dismantle the unit
Remove front cover, filter, fan housing. Photograph the as-found state — biofilm extent, drain-pan condition. Useful for warranty + before-after evidence.
02
Soak + brush the coil
Apply chemical (we use a coil-safe alkaline solution, not the cheap acid-based ones that corrode fins). Soak 15-30 min depending on buildup, then soft-brush.
03
Flush + rinse
Pressurised rinse, multiple cycles, until run-off water is clear. We collect the run-off in a tray — no mess in your room.
04
Clean drain pan + line
Drain pan removed, scrubbed, sanitised. Drain line flushed + cleared of any partial clog. This is often where the smell really lives.
05
Reassemble + cooling test
Filter cleaned + replaced, fan housing back in, front cover, vacuum off any debris. Run full cooling cycle for 15 min to confirm temperature drop + no leaks.
