Whats the Most Energy-Efficient AC Setting?

You shouldn’t have to give up comfort or drain your wallet to keep your house at a pleasant setting during the summer.

But what is the best temp, exactly? We review ideas from energy pros so you can determine the best temp for your house.

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

Recommended Thermostat Settings for Summer

Most households find placing the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a sizeable difference between your interior and exterior temperatures, your AC bills will be bigger.

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

While at home: 78 degrees. While that appears warm, there are ways you can keep your home refreshing without having the air conditioning running frequently.

Keeping windows and blinds closed during the day keeps cool air where it should be—indoors. Some window treatments, including honeycomb shades or plantation shutters, are designed to deliver extra insulation and improved energy savings.

If you have ceiling fans in your residence, the DOE says you can move thermostat temperatures about 4 degrees hotter without compromising comfort. That’s due to the fact they cool by a windchill effect. Since they cool people, not spaces, turn them off when you leave a room.

If 78 degrees still seems too warm on the surface, try conducting an experiment for approximately a week. Start by increasing your thermostat to 78 degrees while you’re at your house. Then, gradually turn it down while using the advice above. You could be shocked at how comfortable you feel at a warmer temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioner running all day while your house is vacant. Switching the temperature 7¬¬–10 degrees hotter can save you an estimated 5–15% on your air conditioning bills, according to the DOE.

When you get home, don’t be tempted to switch your thermostat below 78 to cool your house more rapidly. This isn’t effective and typically results in a more expensive cooling expense.

A programmable thermostat is a good method to keep your temp controlled, but you have to set programs. If you don’t use programs, you might forget to increase the set temperature when you go.

If you need a handy solution, think over installing a smart thermostat. This thermostat works with with your phone, so it knows when you’re at your residence and when you’re gone. Then it instinctively adjusts temperature settings for the biggest savings. How much exactly? Typically $180 each year on heating and cooling, according to ENERGY STAR.

Another advantage of having a smart thermostat? You can use your phone to keep an eye on and change temperature settings from almost anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR advises 82 degrees, that may be too uncomfortable for many families. The majority of people sleep better when their sleeping space is chilly, so that’s why the National Sleep Foundation advises 60–67 degrees. But that might be too cool, due to your pajama and blanket preference.

We suggest using a similar test over a week, putting your thermostat higher and progressively decreasing it to choose the right temperature for your house. On cool nights, you could learn keeping windows open at night and running a ceiling fan is a preferable option than using the AC.

More Ways to Use Less Energy During Hot Weather

There are other ways you can conserve money on air conditioning bills throughout the summer.

  1. Install an energy-efficient air conditioning system. Central air conditioners only last about 12–15 years and become less efficient as they become older. An updated air conditioner can keep your house cooler while keeping cooling
  2. bills down.
  3. Book regular air conditioning tune-ups. Routine air conditioner maintenance keeps your equipment running properly and may help it operate at better efficiency. It might also help lengthen its life expectancy, since it helps techs to discover small problems before they lead to a big meltdown.
  4. Switch air filters often. Read manufacturer instructions for switching your air filter. A dirty filter can cause your system to short cycle, or turn on and off too often, and drive up your utility
  5. costs.
  6. Inspect attic insulation levels. Just about 90% of houses in the USA don’t have enough insulation, according to the Insulation Institute. Most southern climates should have 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork examined. Ductwork that has come apart over time can seep cold air into your attic, walls or crawl space. This can result in major comfort troubles in your home, like hot and cold spots.
  8. Seal openings, doors and windows. Keep humid air in its place by sealing openings. You can also caulk or weather strip doors to trap more cool air inside.
