Have your air conditioner serviced at the beginning of summer (or if you have an older model upgrade to a more energy efficient one). Make sure to clean filters regularly.
Turn off your aircon before you leave the house or at the very least turn up the thermostat.
A fan can work wonders. Don’t forget fans only work when someone enjoys their breeze. Turn off the fan when you leave the room.
Ceiling fans have to be set in a counterclockwise motion so cool air is pulled upwards and circulates around the room.
Blinds & curtains
It’s a no-brainer yet super effective. Keep your blinds and curtains closed when you leave your house and during the hottest time of day. At night, leave your windows and curtains open to enjoy a cooling draft.
A dryer uses energy and generates heat. Use the power of the sun to dry your clothes.
Trees and awnings provide shade that helps keep the inside temperature low.
Open Air Cooking
Heat up your food, not your house. Cooking generates heat. If possible, use your barbeque and cook outside or have cold meals for a change.
