Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to give up comfort or empty your wallet to keep your house at a refreshing temp during warm days.

But what is the ideal temp, exactly? We review recommendations from energy pros so you can select the best setting for your house.

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

Recommended Thermostat Settings for Summer

Most families find setting the thermostat at 72-73 degrees is most comfortable. However, if there’s a huge difference between your inside and outdoor temperatures, your cooling costs will be higher.

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 methods you can keep your home pleasant without having the AC going all the time.

Keeping windows and curtains down during the day keeps chilled air where it belongs—within your home. Some window treatments, like honeycomb shades or plantation shutters, are created to provide extra insulation and improved energy conservation.

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

If 78 degrees still feels too warm on the surface, try running a test for about a week. Begin by increasing your thermostat to 78 degrees while you’re at your house. Then, steadily decrease it while using the tips above. You may be shocked at how cool you feel at a higher temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioner working all day while your home is vacant. Switching the setting 7¬¬–10 degrees warmer can save you an estimated 5–15% on your cooling expenses, according to the DOE.

When you come home, don’t be tempted to put your thermostat colder than 78 to cool your house faster. This isn’t effective and often produces a more expensive electrical expense.

A programmable thermostat is a helpful method to keep your settings controlled, but you need to set programs. If you don’t use programs, you run the risk of forgetting to increase the set temperature when you go.

If you’re looking for a convenient resolution, think over buying a smart thermostat. This thermostat links with your phone, so it knows when you’re at home and when you’re out. Then it automatically changes temperature settings for the biggest savings. How much exactly? About $180 annually on heating and cooling, according to ENERGY STAR.

Another perk of using a smart thermostat? You can use your phone to watch and adjust temperature settings from nearly anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR recommends 82 degrees, that might be unbearable for many families. Most people sleep better when their sleeping area is chilly, so that’s why the National Sleep Foundation suggests 60–67 degrees. But that might be too cold, due to your PJ and blanket preference.

We recommend using a comparable test over a week, setting your temp higher and gradually turning it down to pinpoint the best setting for your family. On pleasant nights, you might find keeping windows open at night and using a ceiling fan is a preferable option than running the air conditioning.

More Approaches to Use Less Energy During Warm Weather

There are extra methods you can conserve money on energy bills throughout warm weather.

  1. Get an energy-efficient AC system. Central air conditioners only work for about 12–15 years and lose efficiency as they age. A new air conditioner can keep your home comfier while keeping AC
  2. expenses low.
  3. Book regular air conditioner tune-ups. Routine air conditioner maintenance keeps your equipment working smoothly and may help it work at better efficiency. It could also help extend its life expectancy, since it helps professionals to uncover little problems before they create an expensive meltdown.
  4. Replace air filters regularly. Read manufacturer instructions for changing your air filter. A dirty filter can lead to your system short cycling, or run too frequently, and raise your electrical
  5. bills.
  6. Inspect attic insulation levels. Nearly 90% of residences 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 should have 16–18”.
  7. Have your ductwork inspected. Ductwork that has separated over time can let conditioned air into your attic, walls or crawl space. This can result in big comfort issues in your home, such as hot and cold spots.
  8. Seal cracks, doors and windows. Keep humid air where it should be by sealing cracks. You can also caulk or weather strip doors to keep more conditioned air inside.
