Split System Cleaning
Mould gone, fresh air restored — Brisbane Northside.
We bring tired split systems back to life — the built-up mould and grime cleared out, so the air comes through fresh and clean again and the unit runs the way it should. A proper deep clean of the whole unit, fixed price upfront, pay after the clean.
- $0 upfront — pay after the clean
- Don't need a clean? We won't charge you
- 60+ min late? $50 off

Our Process
Here's exactly what happens at your split-system clean.
THE 4-STAGE HONEST
DIAGNOSIS CLEAN™
We test, diagnose, treat the right thing, and verify — the same four stages on every split. If a unit doesn't need cleaning, we tell you and we don't charge for it.
Stage 1: Test Before We Touch
Baseline diagnostic
We start with a proper look — including a UV light to spot mould and build-up — on every unit before we lift a cover. That's how we tell you which actually need cleaning and which don't.
Stage 2: Identify the Build-up
Mould vs dust vs algae
Cover comes off and we check the front and back of the coils, the fan barrel, the drain line and the drain pan. Brisbane's humidity, coastal salt air and summer storms build up differently in different houses — so we treat what's actually there.
Stage 3: Targeted Treatment
Real mould treatment that lasts
We treat the mould properly so it doesn't come straight back. We hit the coils, the fan barrel, and flush the drain line. We even clean the back of the coil — that's where the mould actually hides, so it's part of every job.
Stage 4: Verify the Result
Before/after, sent to your phone
We send before-and-after photos of every unit to your phone, so you see exactly what came out — and your aircon comes out running colder and cleaner. Pay after — only when you're satisfied.
Four stages, every job. That's why our cleans actually last.

Done Properly
WHAT A PROPER SPLIT CLEAN COVERS
The indoor coil is where most of the dirt and mould lives — so that's where the real work is. Here's the full order we work through on every split, so you know exactly what you're paying for.
STEP 1 · COVER + PROTECT
Catch tarp under the unit, towels on the floor, drop sheet covering anything underneath. We don't make a mess in your house, and if anything inside the unit drips during the clean it lands in the tarp not on your floor.
STEP 2 · OPEN + INSPECT
Front cover off, filter out, blower wheel checked. We take a quick photo of the state of the coil before we start so you can see the before. Most splits we open up in Brisbane look like they've never been touched — black biofilm, brown dust mat on the fins.
STEP 3 · CHEMICAL WASH THE COIL
This is the step that actually clears the built-up mould and grime. We spray a biocidal cleaner across the indoor coil fins, let it sit and break down the dirt, then high-pressure rinse it. The runoff goes into the tarp. The coil comes out the colour the manufacturer intended.
STEP 4 · DRAIN PAN + LINE FLUSH
Drain pan vacuumed and biocide-flushed. Drain line flushed from inside out. This is what stops the #1 service call in Brisbane — water dripping from the indoor unit because the drain line clogged with algae.
STEP 5 · FILTER + REASSEMBLE
Filter washed in antibacterial solution, dried, popped back in. (If the filter is damaged we'll tell you and carry common replacements.) Unit reassembled, sealed, powered up.
STEP 6 · PERFORMANCE TEST
Run it on max cooling for 5 mins and check it's blowing properly cold. Most splits we clean gain around 3-6°C of cooling capacity back — you'll feel the difference straight away.
OPTIONAL · OUTDOOR UNIT ADD-ON
Optional add-on at a flat per-unit rate. Condenser fins washed with low-pressure water (high pressure bends them — careful work). Any clogged grass clippings, pollen, leaves pulled out. Bent fins straightened with a fin comb. Brisbane's pollen season clogs these badly and most homeowners never look at them.
OPTIONAL · ANTI-VIRAL FOG ADD-ON
Ask us about our on-site anti-viral fog add-on. After the deep clean, we can run a hospital-grade biocidal fog through every internal surface of the unit. Worth a chat for households with asthma, immune-compromised members, or anyone after the highest air quality we can deliver. We sort the details on the day.
Real Brisbane Coils
That's the process — here's the proof.

Real coils from Brisbane Northside splits we've cleaned. Slide to see what was hiding inside.

Before: that musty smell when it kicks in. Weak airflow. Working hard just to keep up.
After: cold, quiet air that smells like nothing — the way it ran when it was new.
On The Tools
THE KIND OF SPLIT JOBS WE DO
Representative of the split-system work we do across Brisbane's Northside — the calls, the finds, and the honest advice that comes with them.
3-BED HOME · 3× SPLITS
Owner thought she needed all three cleaned. We opened the master-bedroom one — basically still clean from a previous job months back — and told her to skip it. Cleaned the living-room unit (filthy) and the spare room (moderate) with the full chemical wash. Saved her the cost of the third clean.
COASTAL PROPERTY · 2× SPLITS
Salt air does a number on outdoor condensers near the bay. Both indoor coils were fine but the outdoor fins were corroding. We cleaned the indoors thoroughly and pointed the owner to a refrigeration specialist for a corrosion-resistant coil coating — that's not work we do, so we put them onto someone who does.
APARTMENT · 1× SPLIT · LANDLORD-PAID
Filter was wrecked, so we replaced it, then chemical-washed the coil. The tenant had mentioned headaches when the AC ran — a few days later they texted to say all good, no headaches. Usually that's mould biofilm on the coil before the clean.
INVESTMENT PROPERTY · 4× SPLITS · END-OF-LEASE
Landlord booked all four for end-of-lease. Previous tenant had been a heavy smoker — coils stained yellow with tar. We pulled every barrel, chemical-washed the lot, and sanitised internal cavities to deal with the smell. Came out looking and smelling new.
