How to set your thermostat

Your thermostat is one of your best defenses against high energy bills in the summer. The U.S. Department of Energy offers guidance on temperature settings to help keep energy usage and costs lower.

  • When you’re home and awake, set the thermostat on the air conditioning to 78°F. 
  • Shut off the A/C or program it to turn off during the hours you’re out of the house. 

The Department of Energy also says that adjusting your thermostat by 7°F for eight hours a day during cooling season can help cut your energy costs by 10%. If you don’t think that’s a lot, consider that cooling makes up about half of your energy costs in the summer. Look at last summer’s energy bills and you’ll see what a big difference this can make in how much you’ll pay!

Upgrade your thermostat

Do you still have one of those old-school thermostats with a dial? If so, a small investment in a programmable or smart thermostat can be a big help when it comes to optimizing your air conditioning usage.

You can easily find programmable or smart thermostats at your local home improvement store or online. With smart thermostats, you can monitor and control your HVAC system from your smartphone or tablet if you have a WiFi or cellular connection. They can even learn your family’s cooling and heating preferences and adjust the thermostat accordingly. Some smart thermostats can also notify you if your HVAC system needs service.

Smart and programmable thermostats make keeping your energy costs down a no-brainer. That’s because once you program them, you need never worry again about forgetting to turn off the A/C before leaving home for the day. Follow these Department of Energy tips for making the most of your programmable or smart thermostat in the summer.

  • Program the air conditioning to shut off 20-30 minutes before you leave home each day and set it to return to normal comfort levels 20 to 30 minutes before you come home. 
  • Program reductions in cooling to begin 60 minutes before you go to sleep and return them to normal comfort levels 30 minutes before you awaken. 

You can also have multiple settings so if you’re going away for either the weekend of a longer summer vacation, you can program the air conditioning to shut off when you leave, and then turn back on an hour before you come home so the home is cool when you get home.
