Why It Matters: Aussie Homes, Real Risks

Australia’s weather may change from state to state, but one thing's for sure—we love our split systems. Whether you’re cooling down in Darwin or heating up in Hobart, these units are working hard.

But here’s the kicker: the mix of electricity, condensation, and DIY cleaning sprays? It can be risky business if you’re not careful.

Electrical faults from incorrect cleaning can lead to:

• Minor shocks or burnt-out circuits
• Water damage to internal boards
• Blown fuses or tripped RCDs (safety switches)
• Voided warranties from improper handling

According to AS/NZS 3000:2018, all fixed appliances (like wall-mounted split systems) need to be cleaned and maintained safely to avoid electrical hazards.

And no—you don’t have to be a sparkie to stay safe. You just need to follow the right steps.

How It Works: Understanding Where the Danger Lies

Your split system isn’t just blowing air. It’s running refrigerant, managing electrical components, and draining moisture—all at once. And when you open the front panel or spray the coils, you’re interacting with key components that carry live current or are sensitive to water.

Here’s a quick map of what’s inside:

Indoors (head unit):

• Filters (safe to clean)
• Coil and fan (safe with the right spray and bag)
• Circuit board and connections (⚠️ don’t touch!)

Outdoors (condenser):

• Fan and compressor (encased but active)
• Wiring box and terminals (⚠️ licensed techs only)

The golden rule? Always isolate the power before cleaning. That means switching it off at the wall AND the main circuit if needed.

Aussie Tips: Cleaning Safely Without Zapping Yourself

You don’t need a toolbox and a TAFE cert to clean smart. Here are safety-first habits Aussie tradies and homeowners recommend:

Step 1: Power Down Properly

• Turn off the unit with the remote
• Switch it off at the wall
• If unsure, flick the circuit breaker to your aircon zone

Step 2: Use the Right Tools

• Avoid random sprays or kitchen cleaners
• Use AC-specific coil cleaner and protective bags
• Keep water and spray away from wiring points

Step 3: Ventilate the Room

• Open a window when spraying
• Let fumes clear before turning the system back on

Step 4: Dry Completely Before Restarting

• Wait 30–60 minutes after spraying coils
• Reinstall filters when bone dry

Step 5: Know Your Limits

• If anything looks off (loose wires, water near controls, buzzing), stop and call a pro

Maintenance Must-Knows (and Legal Basics)

Regular cleaning isn't just smart—it can also protect you under warranty and Australian law.

Here’s what to remember:

• AS/NZS 3000:2018 requires all electrical appliances to be used and maintained in a safe way
• If water enters electrical areas, your warranty can be voided
• Tenants are typically responsible for basic filter cleaning (check your lease!)
• Homeowners should clean filters every month during summer and schedule a full clean at least twice a year
• Never clean near open terminals or damaged casing—get a licenced electrician involved

When to Upgrade: Signs Safety is at Risk

If your system ticks any of these boxes, a deep clean won’t be enough:

• It’s 10+ years old and has never had a proper clean
• You see rust or water marks near the electrical housing
• It trips the safety switch every time it runs
• You hear buzzing or notice a smell when it starts up

Time to chat to a professional. Older systems don’t just use more power—they can pose a real electrical hazard if neglected.

Client Story: Tammy from Bendigo

Tammy had always cleaned her AC filters with a quick vacuum once in a while. “I thought I was doing the right thing,” she said.

One afternoon, she noticed a flicker when switching her split system on—and then, nothing.

“I sprayed the coil while it was still plugged in… water must’ve gotten into the board.”

A local tradie came to inspect it. “He said I was lucky it didn’t fry the unit—or me.”

Now Tammy uses a cleaning bag and always switches off at the breaker. “I also follow a guide now—no more winging it. Peace of mind is everything.”

Don’t let a simple clean become an electrical headache. With the right gear and a bit of know-how, you can keep your aircon fresh and safe.
