I’ve made this mistake before. Every year, I wait until the first properly stinking hot day to switch on the air conditioner, and every year I’m reminded why that’s a bad idea. Either the unit sounds like it’s dying, or it’s blowing lukewarm air, or I’m on hold with three different installers who are all booked out until mid January.
This year the Bureau of Meteorology is forecasting a warmer than average spring across most of the country. Sydney and Brisbane have already had genuinely hot days, and Melbourne, Canberra and Adelaide have all clocked warmer than usual starts to the season. Translation: summer isn’t waiting for us to be ready.
Midea, one of the world’s largest residential air conditioning manufacturers, is calling September “National Air Con Test Month,” and while that’s clearly a marketing hook, the logic underneath it holds up. Their ANZ team told me the pattern is the same every year.
“We always see a spike in residential air conditioning enquiries during the first heatwave of the season,” said John Milonas of Midea ANZ. “That’s when demand for stock and installation bookings spike, which can lead to significant wait times. National Air Con Test Month, which coincides with the start of Spring, is a smart window for Australians to get air conditioning systems tested or upgraded, while technicians aren’t booked out weeks in advance and there’s plenty of stock on the shelves.”
The Pre Summer Checklist
Before you decide whether to repair, replace or do nothing, run through this:
- Switch it to cooling mode now. Don’t let the first test run be on the hottest day of the year.
- Check the airflow. If you’ve got zoned cooling, cycle through each zone and confirm the fan speed actually changes the flow.
- Clean or replace the filters. A quick brush or hose down often fixes weak airflow. If the filter’s worn out, that’s your answer.
- Listen for strain. A unit working harder than it should is usually a unit costing you more than it should.
- Time the cool down. Track the room temperature before and after you turn the system on, to confirm it’s actually doing its job.
If any of that raises red flags, spring is genuinely the better time to book a service or a replacement. It’s the off peak season for installers, which means more stock and shorter wait times than you’ll get in the lead up to Christmas.
If You’re in the Market for a New Unit
For anyone whose system fails that checklist, Midea’s Athena, Edith and Venus series are worth a look. A few features stood out to me:
- AI ECOMASTER, trained on billions of data points, aims to cut heating and cooling costs by more than 30% in the Athena series by reducing temperature fluctuation and wasted energy.
- Cool Flash, available on Athena and Edith units, claims to drop room temperature by 6°C in 10 minutes, useful for the first properly brutal afternoon of the season.
- Air Magic+, exclusive to Athena, adds a built-in negative ion generator that Midea says eliminates up to 99% of viruses and bacteria, a feature recognised by the National Asthma Council’s Sensitive Choice program.
- The SmartHome App across all three series lets you track energy use and pre cool your home before you walk in the door, which is a small thing that makes a real difference on a 40 degree day.
Whether or not you go with Midea specifically, the timing advice is sound. Test now, decide now, and you’ll avoid being one of the thousands of people fighting for the same installer slot in the middle of a heatwave.
