Whats the Most Energy-Efficient AC Setting?

You shouldn’t have to give up comfort or drain your wallet to keep your home at a refreshing temp during hot days.

But what is the best setting, exactly? We discuss ideas from energy pros so you can choose the best setting for your residence.

Here’s what we recommend for the most energy-efficient setting for air conditioning in Opelika.

Recommended Thermostat Settings for Summer

Most people find setting the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a big difference between your inside and outside temps, your utility bills will be greater.

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

While at home: 78 degrees. While that seems warm, there are approaches you can keep your residence pleasant without having the air conditioner on all the time.

Keeping windows and curtains closed during the day keeps cold air where it should be—inside. Some window coverings, such as honeycomb shades or plantation shutters, are created to offer added insulation and better energy savings.

If you have ceiling fans in your residence, the DOE says you can increase thermostat settings about 4 degrees warmer without sacrificing comfort. That’s since they cool through a windchill effect. As they cool people, not areas, switch them off when you move from a room.

If 78 degrees still seems too uncomfortable on the surface, try doing an experiment for approximately a week. Get started by raising your setting to 78 degrees while you’re at your house. Then, gradually turn it down while using the tips above. You could be surprised at how cool you feel at a hotter temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioning running all day while your home is vacant. Moving the temperature 7¬¬–10 degrees hotter can save you as much as 5–15% on your AC costs, according to the DOE.

When you come home, don’t be tempted to set your thermostat under 78 to cool your house faster. This isn’t productive and typically leads to a more expensive cooling expense.

A programmable thermostat is a good approach to keep your settings under control, but you need to set programs. If you don’t use programs, you risk forgetting to raise the set temperature when you take off.

If you need a handy solution, consider installing a smart thermostat. This thermostat connects with your phone, so it knows when you’re at home and when you’re away. Then it instinctively adjusts temperature settings for maximum savings. How much exactly? Typically $180 yearly on heating and cooling, according to ENERGY STAR.

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

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

We suggest trying an equivalent test over a week, putting your thermostat higher and gradually decreasing it to locate the best temp for your house. On mild nights, you may discover keeping windows open at night and running a ceiling fan is a superior option than using the air conditioner.

More Ways to Save Energy During Hot Weather

There are added methods you can conserve money on air conditioning bills throughout hot weather.

  1. Buy an energy-efficient AC system. Central air conditioners only last about 12–15 years and get less efficient as they become older. An upgraded air conditioner can keep your house comfier while keeping electricity
  2. bills low.
  3. Set regular AC tune-ups. Annual air conditioner maintenance keeps your unit operating smoothly and could help it work at better efficiency. It can also help prolong its life span, since it enables technicians to pinpoint small problems before they create a big meltdown.
  4. Put in new air filters regularly. Use manufacturer instructions for changing your air filter. A clogged filter can cause your system to short cycle, or switch on and off too frequently, and increase your electricity
  5. bills.
  6. Inspect attic insulation levels. Just about 90% of houses in the United States don’t have adequate insulation, according to the Insulation Institute. Most southern climates should have 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork examined. Ductwork that has come apart over time can seep cool air into your attic, walls or crawl space. This can lead to big comfort problems in your residence, like hot and cold spots.
  8. Seal cracks, doors and windows. Keep humid air where it belongs by plugging holes. You can also caulk or weather strip doors to keep more cool air indoors.
