Why Your Aircon Needs a Chemical Wash
Over time, your aircon’s evaporator coil, blower wheel, and drainage tray accumulate dust, mould, and bacteria. Regular servicing removes surface dirt, but a chemical wash penetrates deep into these components to dissolve stubborn buildup that general cleaning can’t reach.
Signs Your Aircon Needs a Chemical Wash
- Reduced cooling — Your aircon runs but doesn’t cool the room effectively
- Musty or foul smell — Mould and bacteria growth inside the unit
- Water leaking — Clogged drainage caused by dirt buildup
- Higher electricity bills — The unit works harder to maintain temperature
- Visible mould — Dark spots on the fan coil or blower wheel
Our Chemical Wash Process
Non-Dismantle Chemical Wash ($80/unit)
Our standard chemical wash cleans your aircon without removing it from the wall. We apply safe, formulated alkaline cleaner to the evaporator coil, blower wheel, and drainage tray. This dissolves dirt and bacteria, which is then flushed out through the drainage system.
Best for: Regular maintenance, mild odour, slight drop in cooling performance.
Chemical Overhaul ($130/unit)
For severely choked or neglected units, our chemical overhaul involves completely dismantling the fan coil unit. Every component — the evaporator coil, blower wheel, fan rotor, and drainage tray — is individually soaked and scrubbed in chemical solution for maximum cleaning.
Best for: Units that haven’t been serviced in over a year, severe mould issues, units that still smell after a regular chemical wash.

What Our Customers Say
"Got my 3 aircon units serviced (general cleaning, chemical treatment and gas top-up), and work was done well. Brendon was very professional and made sure to explain to me what the condition/issues of the units are before doing any additional work."
— Nicole Golloso
"Their aircon technician automatically did thorough assessment on my aircon units even though I did not request to do so. A chemical wash was needed which no one told us before. After this session, my aircon is finally blowing cold air."
