Best AC temperature to save power

During extreme summer heat using an air conditioner (AC) for long hours can become necessary.  However the longer the AC runs the higher the electricity bill can be. So, how can you keep your home cool without spending too much on electricity?

One simple way is to set the AC temperature wisely.

Electricity consumption does not depend only on the temperature setting. Several other factors also matter including the size of the room AC efficiency outdoor temperature, humidity and the number of hours the AC is running. Setting the AC at a very low temperature can make the compressor work for longer periods. Raising the temperature by a few degrees can help reduce electricity use.

Some estimates suggest that increasing the setting by just one degree can lower energy consumption by around 1 to 3 percent.

For example, running an AC at 26°C instead of 22°C can use significantly less electricity while still keeping the room comfortable.

There is no single temperature that works perfectly for every home. The best setting depends on your daily routine. If people stay at home throughout the day a comfortable temperature may be needed.

But if the house is empty for several hours increasing the temperature instead of keeping the AC very cold can help save energy.

Turning the AC completely off is not always the best option during very hot weather. When you return the unit may need to work harder for some time to cool the room again.

Setting a higher temperature while you are away can be a more practical choice.

Humidity is another important factor. High humidity can make the same temperature feel hotter and more uncomfortable. People living in humid areas may need a slightly lower setting while those in dry areas may feel comfortable at a higher temperature.

The time of day also matters. During the afternoon strong sunlight and higher outdoor temperatures can put more pressure on the AC.

In the morning and evening you may be able to increase the temperature while remaining comfortable.

At night many people prefer a cool room for better sleep. However there is usually no need to set the AC to an extremely low temperature.  A setting between 24°C and 26°C can offer a good balance between comfort and energy savings.

The simple rule is

set your AC as high as you can while still feeling comfortable. Even a small increase in temperature can help reduce electricity consumption and lower your monthly bill
