Whats the Most Energy-Efficient AC Setting?

You shouldn’t have to give up comfort or spend a lot to keep your house at a pleasant temperature during the summer.

But what is the ideal setting, exactly? We discuss recommendations from energy specialists so you can determine the best temperature for your residence.

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

Recommended Thermostat Settings for Summer

Most people find placing the thermostat at 72-73 degrees is ideal. However, if there’s a huge difference between your inside and outside temperatures, your cooling costs will be larger.

These are our suggestions based on the U.S. Department of Energy (DOE) and ENERGY STAR®.

While at home: 78 degrees. While that sounds too high, there are ways you can keep your home cool without having the air conditioner going constantly.

Keeping windows and curtains closed during the day keeps chilled air where it belongs—indoors. Some window coverings, including honeycomb shades or plantation shutters, are designed to give added insulation and improved energy conservation.

If you have ceiling fans in your residence, the DOE says you can move thermostat temps about 4 degrees warmer without giving up comfort. That’s since they cool by a windchill effect. Because they cool people, not spaces, turn them off when you move from a room.

If 78 degrees still feels too warm on the surface, try conducting a test for a week or so. Begin by upping your thermostat to 78 degrees while you’re at your residence. Then, gradually turn it down while following the advice above. You could be surprised at how cool you feel at a higher temperature setting.

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

When you get home, don’t be tempted to put your thermostat colder than 78 to cool your house more quickly. This isn’t useful and often produces a more expensive AC cost.

A programmable thermostat is a helpful method to keep your temp under control, but you have to set programs. If you don’t set programs, you risk forgetting to raise the set temperature when you leave.

If you want a handy solution, think over installing a smart thermostat. This thermostat links with your phone, so it realizes when you’re at home 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 perk of having 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 suggests 82 degrees, that might be unbearable for many families. The majority of people sleep better when their sleeping space is cold, so that’s why the National Sleep Foundation suggests 60–67 degrees. But that could be too cold, depending on your pajama and blanket preference.

We advise using an equivalent test over a week, setting your thermostat higher and gradually decreasing it to choose the ideal temperature for your residence. On cool nights, you could find keeping windows open at night and using a ceiling fan is a better solution than using the air conditioner.

More Approaches to Save Energy During Warm Weather

There are additional ways you can conserve money on energy bills throughout warm weather.

  1. Install an energy-efficient cooling system. Central air conditioners only are effective for about 12–15 years and lose efficiency as they age. An upgraded air conditioner can keep your residence cooler while keeping energy
  2. bills low.
  3. Schedule regular air conditioner maintenance. Routine air conditioner maintenance keeps your system running like it should and may help it work at better efficiency. It may also help prolong its life cycle, since it helps professionals to uncover little issues before they create an expensive meltdown.
  4. Switch air filters often. Use manufacturer instructions for changing your air filter. A dirty filter can result in your system short cycling, or turn on and off too frequently, and drive up your cooling
  5. costs.
  6. Check attic insulation levels. Almost 90% of residences in the USA don’t have proper insulation, according to the Insulation Institute. Many southern climates need 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork inspected. Ductwork that has come apart over time can leak conditioned air into your attic, walls or crawl space. This can lead to major comfort issues in your home, like hot and cold spots.
  8. Seal openings, doors and windows. Keep humid air in its place by plugging openings. You can also caulk or weather strip doors to trap more cold air indoors.
