What chemical wash actually does

Normal AC service cleans what's accessible from the outside — filter, visible coil face, drain line. It doesn't reach the fouling that builds up inside the coil fins after 12–24 months of operation. That deeper fouling is what reduces cooling capacity, increases energy use, and produces the musty smell that air freshener can't mask.

Chemical wash strips that out. We dismantle the indoor unit, soak the coils in a coil-safe chemical solution that dissolves the fouling, high-pressure rinse it all out, treat the drain pan with biocide to prevent mould regrowth, deodorise, and reassemble.

When you need one

Schedule a chemical wash if any of these apply.

ac_unit

AC cooling has noticeably reduced despite recent normal service

Persistent musty smell when the unit runs

biotech

Visible mould around the vents

Buying a property — service everything before moving in

Our process

Six steps. Same for every chemical wash.

01

Power down and dismantle

We remove the indoor unit cover, blower wheel, and where required the full indoor unit from the wall (carefully, with sheet protection on your wall and floor).

02

Chemical soak

Coil-safe solution applied via low-pressure sprayer, left to dwell for 10–15 minutes.

03

High-pressure rinse

Proper rinse, multiple passes until water runs clear.

04

Drain pan treatment

Biocide applied, drain line flushed with treatment to prevent algae regrowth.

05

Deodorise

Final spray with a coil-safe deodoriser.

06

Reassemble and commission

Run through cooling/fan modes, verify drain flow and temperature differential.

What we don't do

Three shortcuts you may have been quoted elsewhere.

do_not_disturb_on

No garden-water rinse

We don't pressure-wash coils with garden water (the standard shortcut in this market). It's faster, looks similar from the outside, and ruins coils faster.

block

No solvent-based cleaners

We don't use solvent-based cleaners that strip the aluminium fin coating.

cancel

No skipping the drain pan

We don't skip the drain pan treatment.

Frequently asked questions

Every 12–24 months for heavy use (daily 8+ hours), every 2–3 years for light use. Earlier if you have visible mould around vents, persistent musty smell when the unit runs, or significantly reduced cooling despite recent normal servicing.
