Whats the Most Energy-Efficient AC Setting?

You shouldn’t be forced to compromise on comfort or empty your wallet to keep your house at the right temp during muggy weather.

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

Here’s what we advise 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 approaches you can keep your residence cool without having the AC going all the time.

Keeping windows and window treatments shut during the day keeps cold air where it should be—indoors. Some window treatments, like honeycomb shades or plantation shutters, are made 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 compromising comfort. That’s because they cool with a windchill effect. Since they cool people, not rooms, switch them off when you exit a room.

If 78 degrees still appears too uncomfortable at first glance, try conducting a trial for approximately a week. Get started by raising your temperature to 78 degrees while you’re at your residence. Then, progressively turn it down while following the ideas above. You might be surprised at how refreshed you feel at a higher temperature setting.

While away: 88 degrees. There’s no need to keep the AC working all day while your home is vacant. Switching the temp 7¬¬–10 degrees warmer can save you as much as 5–15% on your electricity expenses, according to the DOE.

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

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

If you want a hassle-free solution, think over buying 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 biggest savings. How much exactly? Typically $180 annually on heating and cooling, according to ENERGY STAR.

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

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

We suggest running an equivalent test over a week, putting your temperature higher and progressively lowering it to pinpoint the best temp for your residence. On cool nights, you may learn keeping windows open at night and using a ceiling fan is a superior solution than running the air conditioner.

More Approaches to Conserve Energy During Warm 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 get less efficient as they age. A new air conditioner can keep your house comfier while keeping utility
  2. bills down.
  3. Set yearly AC tune-ups. Routine air conditioner maintenance keeps your system working like it should and could 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 major meltdown.
  4. Change air filters frequently. Read manufacturer instructions for replacing your air filter. A dirty filter can lead to your system short cycling, or switch on and off too often, and drive up your utility
  5. expenses.
  6. Inspect attic insulation levels. Nearly 90% of homes in the U.S. don’t have proper insulation, according to the Insulation Institute. The majority of southern climates require 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 conditioned air into your attic, walls or crawl space. This can create major comfort issues in your residence, like hot and cold spots.
  8. Seal holes, doors and windows. Keep hot air where it belongs by plugging openings. You can also caulk or weather strip doors to seal more conditioned air inside.
