As the Aussie summer fades and the chilly mornings creep in, it’s time to swap the ceiling fans for fluffy socks—and give your air conditioner a little TLC before winter sets in.
You might not think much about your air con when the temps drop, but if your unit has reverse cycle capabilities (most do), it’s your best mate for keeping warm and saving on energy bills.
Here’s how to get your system winter-ready and avoid cold surprises when you need it most.
Clean or Replace the Filters
Dirty filters don’t just affect air quality—they make your system work harder and less efficiently.
- Remove the filters and give them a gentle vacuum or wash with warm, soapy water
- Let them dry completely before reinstalling
- If they’re damaged or extra dusty, it might be time for replacements
🛑 Tip: Clean filters = better airflow + lower energy use = happier you.

Wipe Down the Indoor Unit
Dust loves to settle in and around your indoor unit during the off-season. A simple wipe-down of the vents and surrounding area can help prevent build-up and funky smells.
Don’t forget to:
- Check for mould or mildew (especially if it’s been humid)
- Gently clean the louvers (those adjustable fins that direct airflow)
Clear the Outdoor Unit
Your outdoor unit’s been through a lot—sun, wind, rain, maybe a few leaves or even a wayward tennis ball.
- Clear away leaves, dirt, and debris from around the unit
- Make sure there’s at least 30cm of space around it for proper airflow
- If it’s in a high-traffic or garden area, a cover might help in the off-season

Switch to Heating Mode
Yes, it’s a reverse cycle system—but it’s worth double-checking the settings.
- Set your remote to ‘heat’ or the sun symbol
- Aim for a comfortable 20–22°C to avoid blowing out your power bill
- Give it a test run before winter really kicks in
💡 If it’s blowing cold air or making weird noises—give Curran a call.
