Why You Really Need to Clean Your Split System Aircon in FNQ

Let’s Talk Dirty Aircons

If you’ve lived through even one wet season up here in FNQ, you’ll know how much we rely on our split systems to keep life bearable. But here’s something most homeowners don’t realise: your aircon could be making you sick or costing you way more than it should.

I’m Ryan, owner-operator of Chilled Electrical FNQ, and I’ve seen too many aircons around Port Douglas, Mossman and the Tablelands that haven’t been cleaned in years. Let’s break down what happens when you skip your annual clean, and how to stay on top of it without any stress.

Why Split System Aircons Need Cleaning, Especially Up Here

FNQ's humidity is next level. It’s a breeding ground for mould, dust, and bacteria inside your unit, especially if it's been running non-stop over summer.

Here’s what builds up inside your split system:

• Mould spores from damp indoor air
• Fine dust (yep, even in the tropics)
• Pet hair, smoke residue, and pollen
• Moisture build-up that causes rust and corrosion

When your aircon’s full of that gunk, it can’t run properly, and worse, it starts blowing that stuff straight back into your home.

Signs Your Aircon Needs a Clean

You don’t have to be a sparkie to spot when your split system’s crying out for attention. Here’s what to look for:

Common red flags:

• Musty or damp smells when you switch it on
• Visible mould around the vents
• Poor airflow or uneven cooling
• Spikes in your power bill for no clear reason
• Allergy or asthma flare-ups indoors

If you're nodding along to any of these, it’s time to book a proper clean.

Is Your Aircon Making You Sick?

Short answer? It could be.

How dirty aircons affect your health:

• Respiratory irritation: From mould spores and dust
• Sinus problems and headaches
• Allergy symptoms: Sneezing, coughing, itchy eyes
• Poor sleep quality: From bad airflow and stale air

Keeping your split system clean isn’t just about efficiency, it’s about looking after your health, especially if you've got kids, pets, or older folks at home.

How Often Should You Clean Your Split System?

The rule of thumb in FNQ: at least once a year.

If you’ve got pets, someone with asthma, or your aircon’s running year-round (which, let’s be real, it probably is), you might need a clean every 6 months.

What’s Involved in a Professional Clean?

Not all aircon cleans are equal. At Chilled Electrical FNQ, we do more than just wipe the outside and move on.

Our annual split system service includes:

• Full internal clean of coils and filters
• Drainage check and flush
• Mould treatment (safe and effective)
• Inspection for wear, rust, and early signs of damage
• System performance check

It takes about an hour, and we’ll walk you through what we find, no BS, just straight-up advice.

Why Regular Cleans Save You Money

A well-maintained split system can cut your energy usage by up to 30%, no joke. Dirty systems work harder to cool your home, which hikes up your electricity bill and shortens your aircon’s lifespan.

You’ll save on:

• Power bills
• Repair costs from clogged drains or rusted parts
• Having to replace the whole unit years earlier than needed
