A quick overview of how we clean your air conditioner, what you'll notice afterwards, and why it's the best thing you can do for your home.
Full strip-down, deep clean, sanitise, reassemble. Every unit. Every time.
HEPA vacuum. Coil cleaner. Antimicrobial treatment. Full strip and clean — 40-60 minutes per unit.
Jason or a team member will show up at the time confirmed in your booking SMS. We bring everything — HEPA vacuum, coil cleaner, antimicrobial treatment, tools. You don't need to provide anything.
We remove the covers, access the coil, blower wheel, filters, and drain. This is not a "spray and wipe." We open the unit completely so nothing is missed. Drop sheets are laid to protect your floors and walls.
Coils are treated with a specialised alkaline solution that breaks down organic matter without damaging the aluminium fins. The blower wheel (fan) is pulled out and cleaned blade by blade. HEPA vacuum removes all loose dust, spores, and debris before we start.
The drain line is flushed and tested to make sure water flows freely. A blocked drain means water backs up into your walls or ceiling. After everything is clean, we apply an antimicrobial treatment that kills remaining spores and bacteria on contact.
Everything goes back together. We run the unit and confirm airflow, cooling, and drainage are working properly. You'll notice the difference immediately — better airflow, no smell, colder air. The whole process takes 40–60 minutes per unit.
Your AC coil runs at about 5-7°C. When the thermostat clicks off, the coil stays cold and wet for 15–30 minutes in complete darkness. That's perfect conditions for mould. Spores from your indoor air land on the wet coil, germinate within 24–48 hours, and send root-like hyphae into the aluminium fins. Once established, the colony releases spores into your air stream every time the fan runs.
The blower wheel sits downstream of the coil, in cold humid air. Mould grows between the blades, and since this is the component actually throwing air into the room, contamination here goes straight into your breathable air. The musty smell when you turn the AC on is mVOCs — microbial volatile organic compounds — off-gassing from active colonies. That smell was never "normal."
Every 1mm of fouling on the coil reduces heat transfer by 10–15%. A dirty evaporator coil insulates the heat transfer surface — your system runs longer to hit the same temperature. Clean systems use up to 20–30% less electricity. That's real money every quarter on your power bill.
Mould spores are allergens that trigger histamine responses. Common symptoms from dirty AC exposure: nasal congestion, throat irritation, coughing, itchy eyes, morning headaches, fatigue. Asthma exacerbation is well documented with indoor mould exposure. Children and elderly are more susceptible because their respiratory and immune systems are more vulnerable.
No more musty smell when the AC kicks in. The air feels fresher and lighter — that's what happens when you're not blasting air through mould.
With a clean coil doing its job properly, your unit cools the room noticeably faster. Better airflow from a clean blower wheel.
You know what's in your air. No more wondering why you wake up congested. Your family is breathing clean, conditioned air.
Run on fan-only for 10 minutes after cooling — this dries the coil and dramatically reduces mould growth time. The single best thing you can do between cleans. Works for both split and ducted systems.
For split systems — clean your filters every 4–6 weeks — dirty filters restrict airflow and make the system work harder. Most split-system filters pop out and can be rinsed under warm water. Let them dry completely before putting them back.
For ducted systems — check your return air grille filter monthly — the large filter behind the return air grille (usually in a hallway ceiling) catches all the air before it enters the system. Slide it out, vacuum or rinse it, let it dry, slide it back. A clogged return filter starves the whole system and drives up power costs.
Schedule a full clean every 12 months — even with good filter habits, the coil and blower wheel accumulate contamination you can't reach without a strip-down. Annual professional cleaning keeps the system running efficiently and your air quality high.
Watch for warning signs — musty smell on startup, reduced airflow, the AC running longer than usual to cool the room, unexplained congestion or headaches. These all point to a system that needs attention. On ducted systems, check multiple vents — uneven airflow between rooms can indicate a blocked coil or duct issue.
