Setting Your Thermostat in the Summer

Written on: August 1, 2022

Save energy while staying comfortable

Inflation, bringing with it higher prices for groceries, gas, and other everyday essentials, has taken a big bite at our wallets this summer.

If you dread opening your electric bill because you have been using your home’s air conditioning more frequently, we have some tips for setting your thermostat that will help you keep cooling costs down without having to sacrifice comfort.

Be smart with your thermostat

Small changes can add up to big savings! The U.S. Department of Energy says that if you adjust your thermostat by 7° Fahrenheit for eight hours a day during cooling season, you could save 10% on your cooling energy costs.

That 10% may not sound like a lot at first, but you should remember that cooling accounts for 40% to 50% of your energy expenses throughout the summer and is the most significant component of your energy costs.

The Department of Energy has instructions on how to adjust your thermostat to maximize your air conditioning system’s efficiency while minimizing your energy costs.

• 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.

Upgrade your thermostat

Programmable and smart thermostats are fantastic for controlling your cooling expenses. To get the most out of your air conditioning and save money in the summer, however, you must use them correctly.

Here’s how to set your programmable thermostat:

• Program the A/C to shut off 20-30 minutes before you leave home each day; return them to normal comfort levels 20 to 30 minutes before you come home.  
• Set the nighttime adjustment to begin 60 minutes before you go to sleep; return them to normal comfort levels 30 minutes before you awaken. 

If you don’t already have a programmable or smart thermostat, you can get one at your local home improvement store, online, or by calling AFC. Smart thermostats allow you to keep track of and control your HVAC system from your smartphone or tablet wherever you have access to WiFi or cellular service. Some smart thermostats will even learn your family’s cooling and heating preferences and adjust your thermostat accordingly and notify you if your air conditioner needs service or if you need to change the air filter.
