The best time to prep an air conditioner is early spring, before the first heatwave. Waiting until the first 35°C day means everyone else is calling too.
The checklist
1. Rinse the filters under warm water and let them dry.
2. Check the outdoor unit is clear of leaves, grass and cobwebs.
3. Run the unit for 15 minutes and listen for unusual noise.
4. Confirm the drain isn't blocked (no water pooling in the drip tray).
5. Book a professional clean if it's been more than 12 months.
