Whats the Most Energy-Efficient AC Setting?

You shouldn’t need to give up comfort or empty your wallet to keep your residence at the right temp during the summer.

But what is the right temperature, exactly? We discuss suggestions from energy experts so you can choose the best temperature for your family.

Here’s what we suggest for the most energy-efficient setting for air conditioning in St. Louis.

Recommended Thermostat Settings for Summer

Most households find setting the thermostat at 72-73 degrees is most comfortable. However, if there’s a sizeable difference between your inside and outside temperatures, your electricity expenses will be larger.

This is our advice based on the U.S. Department of Energy (DOE) and ENERGY STAR®.

While at home: 78 degrees. While that sounds hot, there are methods you can keep your residence cool without having the AC on all the time.

Keeping windows and window treatments shut during the day keeps chilled air where it should be—indoors. Some window treatments, like honeycomb shades or plantation shutters, are created to give extra insulation and enhanced energy conservation.

If you have ceiling fans in your residence, the DOE says you can increase thermostat temps about 4 degrees hotter without giving up comfort. That’s because they cool with a windchill effect. Since they cool people, not areas, shut them off when you move from a room.

If 78 degrees still seems too warm at first glance, try conducting a test for about a week. Get started by raising your setting to 78 degrees while you’re at your house. Then, progressively turn it down while following the ideas above. You could be astonished at how refreshed you feel at a higher temperature setting.

While away: 88 degrees. There’s no need to keep the AC going all day while your home is vacant. Switching the temp 7¬¬–10 degrees hotter can save you an estimated 5–15% on your cooling expenses, according to the DOE.

When you arrive home, don’t be tempted to put your thermostat below 78 to cool your home more quickly. This isn’t effective and often leads to a more expensive electricity bills.

A programmable thermostat is a good method to keep your settings in check, but you need to set programs. If you don’t use programs, you run the risk of forgetting to raise the set temperature when you leave.

If you need a hassle-free solution, think about getting a smart thermostat. This thermostat links with your phone, so it is aware when you’re at your residence and when you’re gone. Then it automatically changes temperature settings for the best savings. How much exactly? Typically $180 annually on heating and cooling, according to ENERGY STAR.

Another benefit of having a smart thermostat? You can use your phone to monitor and regulate temperature settings from just about anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR advises 82 degrees, that may be unbearable for most families. Most people sleep better when their sleeping space is cold, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that could be too cool, depending on your PJ and blanket preference.

We advise using a comparable test over a week, moving your temperature higher and gradually decreasing it to pinpoint the right temp for your house. On pleasant nights, you may discover keeping windows open at night and using a ceiling fan is a preferable solution than running the air conditioner.

More Methods to Use Less Energy During Hot Weather

There are other ways you can spend less money on AC bills throughout warm weather.

  1. Install an energy-efficient air conditioning system. Central air conditioners only work for about 12–15 years and become less efficient as they age. A new air conditioner can keep your residence cooler while keeping cooling
  2. bills down.
  3. Book regular AC tune-ups. Routine air conditioner maintenance keeps your system operating like it should and might help it operate more efficiently. It might also help prolong its life expectancy, since it allows techs to discover small issues before they cause a big meltdown.
  4. Change air filters frequently. Use manufacturer instructions for replacing your air filter. A dirty filter can result in your system short cycling, or turn on and off too often, and drive up your cooling
  5. expenses.
  6. Inspect attic insulation levels. Nearly 90% of homes in the U.S. don’t have adequate insulation, according to the Insulation Institute. The majority of southern climates should have 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork checked. Ductwork that has separated over the years can seep cold air into your attic, walls or crawl space. This can result in major comfort troubles in your house, like hot and cold spots.
  8. Seal holes, doors and windows. Keep hot air where it belongs by plugging holes. You can also caulk or weather strip doors to trap more conditioned air within your home.
