The ideal temperaturefor air conditioners varies by time of day. During the daytime, setting the temperature between 24°C to 26°C (75°F to 78°F)helps keep rooms cool without using too much energy. This range balances comfort and efficiency, saving money on electricity bills.
For nighttimeadjustments, lowering the temperature slightly to 26°C to 28°C (78°F to 82°F)is recommended. Warmer air at night helps the body rest better and reduces power use. Using a programmable thermostat can make these changes automatic and easy.
Energy Efficiency Tips
Setting your air conditioner at around 78°F (26°C)saves energy and keeps you cool. Programmable thermostats help by adjusting temperatures at different times. For example, raise the temperature when no one is home. Lower it before people return to keep rooms comfortable.
