In Melbourne, where summer temperatures can soar for days at a time, air conditioning offers a much-needed relief. Relying on it too heavily, however, can drive up your electricity bills, especially during peak periods. With no let-up in energy costs on the horizon, it’s more important than ever to find smarter, more efficient ways to cool your home.
Fortunately, we have five practical tips that can help you lower the cost of both heating and cooling in Melbourne without sacrificing comfort.
1. Start With Better Insulation
In summer, good insulation acts like a barrier, keeping hot air out and cool air in. This means that if your ceiling, walls, or even floors are poorly insulated, your air conditioner has to work harder to keep your home comfortable. Insulating your home properly – especially the roof and attic – can reduce heat gain in summer and significantly reduce your cooling costs. It’s a worthwhile investment that pays off all year round.
2. Consider Upgrading to a Modern A/C Unit
If your air conditioning system is over ten years old, it might be time for an upgrade. Modern air conditioners are far more energy-efficient than older models, thanks to advancements in technology and tighter energy standards. Look for systems with high Energy Star ratings, inverter technology, and zoning capabilities. They don’t just cool more effectively – they do it with less power, which means lower bills and a smaller carbon footprint.
3. Use Window Coverings to Block the Heat
Sunlight streaming through your windows might brighten your space, but it can also make it very hot inside your home. Closing curtains, blinds, or using reflective shades during the hottest parts of the day can significantly reduce this indoor heat. If you want to take it a step further, consider installing external shutters or awnings, and if you’re building or renovating, think about window placement and orientation. A well-designed home can reduce heat before it even reaches your A/C.
4. Set Your Thermostat Wisely
A small temperature change can have a big impact on your energy use, so set your thermostat around 24–26 degrees Celsius during summer to keep your home comfortable without overworking your system. You can also use programmable or smart thermostats to fine-tune your cooling schedules, setting the A/C to switch off when no one’s home or reduce cooling overnight – and reap the benefits on your next power bill.
5. Stop Drafts and Improve Ventilation
Air leaks and poor ventilation make it harder for your air conditioner to keep your home cool, leading to higher energy use. So seal gaps around windows, doors, and vents to help trap the cool air inside where it’s needed. Consider installing weather-stripping, caulking, and draft stoppers, as they’re simple fixes that can make a big difference to your energy bills. Good ventilation also plays a role – using ceiling fans to circulate air more effectively throughout your home helps reduce the strain on your system.
Simple Changes, Big Savings
A few smart upgrades and everyday habits can help you stay cool while keeping your energy costs under control. Improving insulation, choosing energy-efficient units, setting your thermostat wisely, and using window coverings to block out heat – all make a noticeable difference. Each of these small changes contributes to more effective cooling and can reduce the strain on your system throughout the warmer months. Working together, they create a more comfortable home without the high energy bills.
