Aircon chemical wash Singapore. When general servicing isn't enough.
An aircon chemical wash Singapore homeowners can actually trust. When your aircon smells, leaks, or just won't cool the way it used to, a normal service won't fix it. A chemical wash deep-cleans the fan coil with specialised chemicals to break down mould, sludge, and bacteria. Flat $80 per unit, full general service included.
Signs your aircon needs a chemical wash
If any of these match your unit, a regular service won't cut it. The grime is too deep, only targeted chemical treatment will dissolve it.
Musty or sour odour
That damp, sour, or stale smell when turning on your unit means bacterial biofilm and mould colonies are breeding inside the cooling fins.
Water dripping from fancoil
Internal drainage lines and back-trays become choked with jelly-like bio-sludge that regular vacuuming alone cannot dissolve.
Weak airflow or warm output
Thick layers of dirt coat the evaporator coils and blower fan, suffocating airflow and forcing the compressor to overwork.
Visible mould or black spots
Black specks appearing around air louvers or on the rotating blower wheel indicate airborne spore growth inside the casing.
No deep clean in 12+ months
Daily use in Singapore’s humid climate causes heavy buildup within a year. A chemical wash restores clean air volume and hygiene.
Spike in electricity bills
Choked heat exchanger coils reduce thermodynamic efficiency, forcing your system to draw significantly more power to cool the room.
We won't push you
If a general service will fix it, that's what we'll recommend. Multiple Google reviews say exactly this.
Aircon-grade chemicals only
Specialised, manufacturer-safe agents. No cheap shortcuts that damage coils or void warranty.
Includes full general service
You're not paying for chemical wash on top of servicing, it's all in the one $80 price.

What's the difference?
Same dismantle, same jet wash. The chemical wash adds specialized chemical treatment of the fan coil, specifically for when grime and mould won't budge with water alone.

Our chemical wash, step by step
Opening steps follow standard general servicing. The specialized chemical-cleaning stages are highlighted below, that is what eliminates stubborn mould and bacteria.
Cover work area & furnishings
Waterproof floor sheets and protective plastic coverings are laid down first to ensure your room and furniture stay completely clean.
Initial operational diagnostic test
We test power on, check airflow volume, listen for internal noises, and identify any pre-existing mechanical issues.
Dismantle front fascia & air filters
Front casing, motorized swing louvers, and filtration frames are carefully unclipped without damaging delicate brackets.
Remove water drainage tray
The internal condensation tray is detached and inspected. This is where standing water and mould accumulation typically originate.
Extract blower wheel
The cross-flow fan roller is detached. Thoroughly cleaning this component prevents airflow choking and rattling vibrations.
Install protective catch bag under fancoil
A specialized waterproof catchment bag is sealed around the mounted coil to capture chemical fluids and rinse water cleanly.
Apply HVAC chemical solution
Specialized coil cleaner is applied across the cooling fins. The formula penetrates deep between micro-fins where regular water cannot reach.
Allow chemical action to break down grime
The solution sits to actively dissolve compacted bio-slime, stubborn fungal colonies, and oxidized deposits within the coil matrix.
High-pressure jet wash coil & parts
Dissolved contaminants are thoroughly flushed using high-pressure jet water, clearing out heavy black sludge from the fins.
Thorough neutral water rinse
Repeated clean-water rinses ensure zero active chemical residue remains, protecting the copper and aluminium from corrosion.
Complete drying before assembly
All disassembled casing parts and blower rollers are dried thoroughly before reattachment to protect electrical components.
Drainage pipe vacuum flush
Drainage lines are vacuumed clear of loosened bio-jelly to eliminate future water clogging and dripping risks.
Reassemble & operational confirmation
Components are reassembled securely. We test cooling output, temperature drop, and smooth fan rotation before completing the job.
Refrigerant pressure gauge inspection
We check system gas pressures during every chemical wash. If refrigerant is low, we advise you transparently before topping up.
One price. No surprises.
Chemical wash is flat-rate per unit, regardless of brand, BTU capacity, or dirt accumulation level. Transparent pricing guaranteed.
