I'm Steve. I've been in air conditioning for over 15 years, and every week I open up split systems across Mission Beach, Tully, Innisfail and Kurrimine Beach. Most of them look fine from the outside. Behind the plastic cover it's a different story. Here's what a professional clean actually does — and why it matters more in FNQ than almost anywhere else in the country.
Why does my aircon feel like it stopped cooling?
Nine times out of ten it's not a gas problem — it's airflow. The evaporator coil behind the front cover is a fine aluminium mesh. In FNQ, that mesh collects dust, pet hair, mould and a sticky biofilm that closes off the gaps air is meant to pass through.
When air can't get across the coil properly, the room takes longer to cool. The unit keeps running. The compressor keeps working. You keep paying. A hydro-chemical clean strips that layer off and the coil breathes again.
Will a clean really lower my power bill?
If the unit is dirty, yes. The compressor is by far the hungriest part of the system. Anything that forces it to run longer to hit the setpoint costs you money on the meter.
I've had customers in Mission Beach ring me a month after a service and tell me the bill dropped by a real, noticeable amount. It's not a lab number and I'm not going to quote you a percentage — the truth is it depends on how bad the unit was when I got to it. But on a heavily fouled unit, the difference is obvious.

Is my aircon making me sick?
If it smells musty, mouldy or like a wet towel, it's blowing bacteria and mould spores into your lungs. There's no polite way to put it.
The fan barrel in a split system spins in a warm, damp housing — perfect conditions for mould in the tropics. I've pulled barrels out of units in Mission Beach that were black with growth. Kids with asthma, older people, anyone with allergies — they cop it worst. A proper clean puts an end to that.
More detail on that side of things: mould in your aircon and why your aircon smells musty.
How much longer will my unit last if I clean it regularly?
A well-maintained split system in FNQ can genuinely go 12–15 years. A neglected one is done in 6–8. The difference is corrosion and strain.
When the coil is choked, the compressor runs hotter and longer than it was designed to. Bearings wear. Capacitors fail earlier. The board cops it. And on the outdoor side, salt spray eats the aluminium fins if nobody's washing them off. A yearly clean is cheap insurance against a replacement that runs into the thousands.
Does salt air really matter that much in Mission Beach?
Yes. If you're within a kilometre of the water — which is most of us — the outdoor unit is under constant attack from salt-laden air. Salt pulls moisture out of the atmosphere and holds it against the aluminium fins and copper connections.
I regularly see outdoor coils in Mission Beach and Kurrimine Beach where the fins have basically crumbled away because the unit was never rinsed. A proper service includes cleaning the outdoor coil, checking the electrical connections for green corrosion, and treating exposed metal where I can.
When's the best time to book?
Before the wet season, ideally. Once the humidity climbs and everyone's units are running 12 hours a day, my calendar fills up fast.
If it's already musty, don't wait — every extra week is more spores blowing into the room. Same-week service is available across the Cassowary Coast.

Frequently asked questions
How often should I get my aircon cleaned in Mission Beach?
In FNQ humidity, once every 12 months is the minimum. If you run the unit hard through the wet season, have pets, or live within a few hundred metres of the beach, every 6–9 months is more realistic. Waiting two or three years is when I start pulling out the really nasty stuff.
Will a professional clean actually lower my power bill?
Yes, if the unit is dirty. A blocked filter and a coil coated in biofilm force the compressor to run longer to hit the same temperature. On the worst units I've serviced, the owners reported their monthly bill dropping noticeably once airflow was restored. It's not magic — it's just the unit doing the work it was designed to do.
How long does a split system clean take?
A standard indoor head unit takes me about 60–90 minutes on site. If it's a multi-head or a ceiling cassette, or if the coil is heavily fouled and needs a proper hydro-chemical wash, expect longer. I'd rather take the extra time than leave gunk behind.
Do you clean the outdoor unit as well?
Yes, and in Mission Beach it matters. Salt spray coats the outdoor coil and eats the aluminium fins. A rinse and a proper coil clean on the outdoor unit is part of a full service — it's not an add-on.
