Three tiers. Pick what fits your system.
Price is for the whole house. Bigger homes / 2-storey / more vents = bump up a tier. We quote upfront so there's no surprises.
"Single-storey, standard system, up to 8 vents"
- Return air filter clean/replace
- Indoor coil clean
- Every ceiling vent cleaned
- Drain pan + line flush
- Health check report
- Coil chemical wash
- Antibacterial fog
"Larger / double-storey, 9-14 vents, make it run like new"
- Everything in Standard
- Coil chemical wash (not wipe)
- Antibacterial vent treatment
- Before/after temp test at vents
- Whole-system fog treatment
"Mould smell, allergies, or hasn't been cleaned in 3+ years"

Big house, lots of vents = Premium. Anything 15+ vents or a return air filter that hasn't been touched in 3+ years = Ultimate. We'll tell you straight on the phone before we book — if Standard fits, we'll book Standard. Saved an Albany Creek customer $200 last month by talking them down from Ultimate when their system only needed Premium.
What "ducted aircon cleaning" actually means
A ducted system has more dirty parts than a split — and they're harder to get at. Here's the order we do it in.
STEP 1 · COVER + ACCESS
Drop sheets under every vent we're touching. Ladder up to the return air grille (usually the big square one in the hallway). We don't walk dirt through your house — booties on, sheets down.
STEP 2 · RETURN AIR FILTER
This is the one part most homeowners never look at — and it pulls every cubic metre of air through it. We pull it out, take a photo (you'll want to see), and either deep-clean it or replace it. Common replacement filters carried on the ute.
STEP 3 · CHEMICAL WASH THE INDOOR COIL
The evaporator coil sits behind the return air grille — wet + dusty = mould factory in Brisbane humidity. Biocidal cleaner across the fins, sit, rinse, runoff into the drain. Wipes alone won't get this clean. Premium and Ultimate tiers include this.
STEP 4 · EVERY CEILING VENT
Each vent — popped off, washed, sanitised, refitted. The black ring you see around the vent is what's been blowing past your face for 12 months. Antibacterial wipe on the surrounding ceiling so the streak doesn't come back.
STEP 5 · DRAIN PAN + LINE FLUSH
Drain pan vacuumed and biocide-flushed. Drain line cleared. Ducted drain lines clog with algae faster than splits in Brisbane — this is what stops water leaks coming through the ceiling 8 months from now.
STEP 6 · PERFORMANCE TEST AT EVERY VENT
Run the system on max cool. Thermal probe at every vent. If one vent is significantly warmer than the others we'll flag it — usually means a duct issue we'd refer to a refrigeration specialist (not us). Numbers go on your receipt.
ULTIMATE · WHOLE-SYSTEM FOG TREATMENT
Antibacterial fog pumped through the return air, distributes through every duct, kills mould spores along the way. The only way to deal with a "musty smell when AC kicks on" properly. Reserved for Ultimate tier because it's expensive and most systems don't need it.
A few jobs from this month
Real Brisbane Northside ducted jobs
BRIDGEMAN DOWNS · 2-storey · 14 vents · Daikin ducted
Owner thought the system was "just getting old". Pulled the return air filter — caked solid, hadn't been changed in 4 years. Replaced it on the spot. Did Premium tier across all 14 vents and the coil. Three days later he texted: "first time the upstairs has actually felt cold all summer."
ALBANY CREEK · Family home · 10 vents · Fujitsu ducted
"Musty smell when the aircon kicks on" — classic mould-in-the-coil call after Brisbane's wet summer. Coil was black, drain line had algae backing up. Did Ultimate tier with whole-system fog. Smell gone the same day. Booked them in for an annual reminder so it doesn't get this bad again.
NORTH LAKES · New build · 8 vents · Mitsubishi ducted
System was only 2 years old. Owner thought "too new to need cleaning" — booked us anyway after a friend recommended. We pulled the filter (light dust, not bad) and showed him the coil (also clean). Did Standard tier as a tune-up, told him to come back in 18 months not 12. Booking value $299 not the $499 we could have upsold him.
EATONS HILL · Rental property · 12 vents · end-of-lease
Property manager booked for end-of-lease clean. Tenant had been heavy cooker — coil and vents had a kitchen-grease haze. Standard tier wouldn't cut it, did Premium with extra coil work. Filter replacement. Took 3 hours instead of the usual 2 — same Premium price, no surprise upcharge. Property re-let within a fortnight.

Common questions about ducted aircon cleaning
How often should I clean a ducted system in Brisbane?
Every 12 months is the standard. Brisbane humidity is harder on ducted systems than southern cities — the indoor coil grows mould faster in our wet summers. If you have pets, run the system most of the day, or have asthma in the house, every 9-10 months is better. Filter check every 3 months yourself in between.
How long does a ducted clean take?
Single-storey 8-vent home: 90 mins. Double-storey 12-14 vents: 2-3 hours. Ultimate tier with fog: add 30-45 mins for the fog to circulate. We don't rush — quote includes whatever time it takes to do it properly.
Will my ducted system run colder after a clean?
Almost always — especially if the return air filter was overdue. We measure airflow temp at every vent before and after. Most ducted cleans pick up 2-5°C of cooling capacity back. Numbers go on your receipt so you see the actual difference.
Do I need duct cleaning too?
90% of the time, no — what people call "duct cleaning" is really "return air filter + coil + vents" cleaning, which is what we do. Actual physical duct cleaning (running a brush through the ducts) is rare and is a different specialty. If we find evidence of mould inside the actual ducts (not just the coil) we'll refer you to a specialist.
What's the difference between this and split system cleaning?
A split has one wall-mounted indoor unit per room. A ducted system has one central unit pushing air through ceiling vents. Different parts to clean (vents instead of indoor heads), different access (ladder + return air grille instead of wall units), different price (whole-house fixed instead of per-unit). If you don't know which you have — look at the ceiling. Square vents = ducted.
What if there's a musty smell from the vents?
Brisbane's classic ducted issue. It's almost always mould on the indoor coil + bacteria in the drain pan, gone unchecked through a wet summer. The fix is Ultimate tier — coil chemical wash + whole-system antibacterial fog. The smell goes the same day. Don't bother trying air fresheners or vinegar tricks, you're just masking the cause.
