Department of Energy. In the summer, keep your thermostat at a minimum of 78°F—no higher. And in the winter, try 68°F.

Most people are actually perfectly comfortable at this temperature—more so than they may think. When elderly relatives or small children live in the home, these settings may not be possible, but they can help most people save money while they are home.

Here is one of the most common misconceptions about heating and air conditioning systems: turning down the temperature all the way will help the home cool off faster, and turning the heat up as high as possible warms a home faster. This simply isn’t the case.

With time, lower temperatures will make the house colder, but it won’t happen any faster. Your air conditioner runs nonstop to reach the setting on the temperature, which is less than what you need to be comfortable. Then, you end up paying way more than you should, and you may not really be comfortable.

The same is true when you continuously get up to adjust the thermostat settings. The AC/heater simply becomes overworked, and this is something you want to avoid. Use your programmable thermostat to keep temperatures stable instead.

When you leave the home, it’s important to use the programming settings on your thermostat to keep temperatures about 10° lower (in the winter) or higher (when it’s hot outside). This way, you don’t waste energy cooling or heating a home that is unoccupied.

However, you don’t want to change the temperature by too much. Let’s say it’s summer and you are away for the day. You shut off the AC completely and turn it on when it gets home. Now, the air conditioner has to work hard to get back up to speed, which may use up even more energy than keeping it at a higher temperature for the day.

Many people are unsure of how to effectively use their thermostats for energy efficiency. Get to know your thermostat by spending some time reading the thermostat. You may be able to use programming options to set different schedules on weekends and weekdays, or to make changes throughout the day.

If your thermostat is over 10 years old, it may be time for a new one. New smart thermostats allow you to set schedules or make changes directly from your smartphone. Ask a local technician about your options.
