4. Minimize heat production
The temperature is already hot, don’t add any more heat. Minimize your heat production. Don’t use your stove or oven during this time. The reason is obvious; they will add heat to your home. When the temperature is already high, the last thing you want to do would be to increase it even further. Instead of using your stove or oven, try grilling. If you want to cook, is to cook outside. Also, to minimize heat production, you can turn off your electronic devices when you’re not using them.
