How to stay cool in summer and save

Whether you’re a renter or a homeowner, there are things you can do to keep cooler in summer and spend less on energy bills. On extreme heat days, knowing how to keep cool at home while using less electricity is also important for our health.

Here are some tips to stay cool for less this summer. Most are easy to do and don’t cost anything.

Don’t let your hard-earned cash fly out the window. Keep cool air inside by closing windows and doors during the day and opening them in the evening to let the cooler air in. When using evaporative cooling, you’ll need to leave some windows slightly open. If you have the air conditioner on, keep windows and doors closed to keep cool air in.

Cool air can escape through gaps and cracks around windows, doors and skirting boards. Seal gaps around windows and doors with sealant using a caulking gun. Door snakes and other draught stoppers can also stop warm air from coming in during the daytime.

Try using fans first. They use less energy than air-conditioners and are cheaper to run.

Set your air conditioner to 23 degrees or higher to maximise energy efficiency and comfort.

Save as much as 10% on your cooling bill with every degree you raise your air-conditioning thermostat during summer.

Turn off air-conditioners when you go out. If you have a smart system, you can also set timers to turn on air-conditioners to cool your home before you arrive.

Remember to keep filters clean on reverse cycle air-conditioners for best performance.

Cover your windows during the day to keep out the sun’s heat.

Inside, fit windows with thermal-backed curtains. Or use honeycomb or roman blinds, which are more energy efficient than other types of blinds. On hot days, close window coverings on windows that get direct sun.

Outside, build shade structures like awnings and shade sails, or plant trees or vines in front of windows. Deciduous trees and plants provide shade in summer while allowing sunlight through in winter. Find the right plant for your home and garden using the Canberra Plant Selector.

Keep your home cool by doing jobs that create heat (like cooking and ironing) during cooler periods of the day. Try to avoid using appliances, like clothes dryers, that create heat.

Save money by switching unused appliances off at the power point. Consider purchasing timers or smart power adaptors that turn many appliances off at once.

Switching to a different energy plan could save you hundreds of dollars a year. Phone around or use the Australian Government’s comparison service, Energy Made Easy.

Your existing energy provider may be able to offer you a better deal to suit your lifestyle and energy use. They can also help you access financial support. Available supports include hardship payments, concessions, payment extensions and flexible payment options.

Save on running costs by upgrading to an efficient reverse-cycle air-conditioner. Reverse-cycle air-conditioning is the most energy efficient form of heating and cooling.

If you’re installing reverse cycle air-conditioning, remember it’s also a heater for winter so remove your gas heating at the same time to save on future running costs.
