1. Make Sure Your Heating System Is Ready
Many WA homes rely on reverse cycle air conditioning for winter warmth. The last thing you want is to turn it on during a cold snap only to discover it’s not working.
- Test your unit now to avoid last-minute surprises.
- Clean or replace filters to ensure proper airflow and efficiency.
- Check the mode — make sure it’s set to ‘HEAT’ and not just blowing cool air.
Tip: Not sure if your reverse cycle air con is actually heating? Use our troubleshooting guide to check airflow, settings and temperature output.
If your current system is struggling or outdated, consider switching to a more efficient option. We offer a range of heating systems for WA homes designed to handle our unique climate.
2. Improve Energy Efficiency to Cut Costs
With energy prices expected to remain high in 2025, energy efficiency is top of mind for many homeowners. You don’t need a renovation — small changes can deliver big savings.
- Seal draughts: Use weather strips or silicone sealant around windows and doors.
- Use thermal curtains: They trap heat inside during cold nights.
- Switch to zoned heating: Heat only the rooms you’re using, especially in the evenings.

3. Clean Gutters and Check Roof Drainage
Wet weather in winter may not be extreme in Perth, but it still puts pressure on your gutters and roofing.
- Clear gutters and downpipes: Remove autumn leaves and debris.
- Check for leaks or sagging: These signs could mean water is backing up or pooling.
- Inspect your roof: Look for cracked tiles, rust spots or moss that may lead to leaks.
Pro tip: Blocked gutters are one of the top causes of water damage in winter — clean them now to avoid expensive repairs later.
4. Prepare Your Reverse Cycle System for Winter Use
Reverse cycle systems are ideal for year-round comfort in WA homes — but switching from cooling to heating isn’t always straightforward.
- Test the heating function early before regular use.
- Book a seasonal service if it hasn’t been looked at in over a year.
- Consider zoning upgrades if you’re planning a system update.

5. Do a Quick Safety and Emergency Check
Winter brings increased use of heaters, power boards, and electric blankets — so safety matters more than ever.
- Test your smoke alarms and replace batteries.
- Check heaters and cords for signs of wear or damage.
- Update your emergency kit with torches, a radio, and extra batteries in case of storm outages.
Bonus tip: Keep a spare power bank charged for your phone in case of a winter blackout.
