Whats the Most Energy-Efficient AC Setting?

You shouldn’t have to sacrifice comfort or empty your wallet to keep your residence at a refreshing temp during the summer.

But what is the best temp, exactly? We discuss suggestions from energy pros so you can select the best setting for your family.

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

Recommended Thermostat Settings for Summer

Most families find placing the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a big difference between your indoor and outdoor warmth, your cooling bills will be higher.

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

While at home: 78 degrees. While that seems too high, there are approaches you can keep your house refreshing without having the AC running constantly.

Keeping windows and blinds shut during the day keeps cold air where it should be—indoors. Some window coverings, like honeycomb shades or plantation shutters, are created to offer extra insulation and better energy conservation.

If you have ceiling fans in your residence, the DOE says you can increase thermostat temperatures about 4 degrees higher without giving up comfort. That’s because they freshen by a windchill effect. As they cool people, not rooms, turn them off when you exit a room.

If 78 degrees still feels too uncomfortable initially, try running a trial for about a week. Start by upping your temperature to 78 degrees while you’re at your residence. Then, gradually decrease it while adhering to the tips above. You may be surprised at how comfortable you feel at a hotter temperature setting.

While away: 88 degrees. There’s no need to keep the air conditioning on all day while your home is empty. Switching the temp 7¬¬–10 degrees hotter can save you an estimated 5–15% on your electrical expenses, according to the DOE.

When you get home, don’t be tempted to switch your thermostat below 78 to cool your home faster. This isn’t useful and typically leads to a more expensive AC cost.

A programmable thermostat is a helpful approach to keep your settings in check, but you have to set programs. If you don’t use programs, you run the risk of forgetting to move the set temperature when you go.

If you need a handy solution, think about getting a smart thermostat. This thermostat works with with your phone, so it is aware when you’re at home and when you’re out. Then it instinctively adjusts temperature settings for maximum savings. How much exactly? About $180 yearly on heating and cooling, according to ENERGY STAR.

Another perk of getting a smart thermostat? You can use your phone to monitor and adjust temperature settings from almost anywhere.

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

We advise trying a similar test over a week, putting your temperature higher and gradually decreasing it to find the ideal setting for your family. On mild nights, you might learn keeping windows open at night and relying on a ceiling fan is a preferable option than operating the air conditioning.

More Ways to Use Less Energy During Warm Weather

There are additional ways you can save money on cooling bills throughout the summer.

  1. Buy an energy-efficient air conditioning system. Central air conditioners only work for about 12–15 years and lose efficiency as they get older. An updated air conditioner can keep your house more comfortable while keeping energy
  2. costs down.
  3. Set yearly AC service. Regular air conditioner maintenance keeps your unit working properly and might help it work at greater efficiency. It can also help lengthen its life expectancy, since it enables techs to uncover seemingly insignificant problems before they lead to a big meltdown.
  4. Switch air filters regularly. Follow manufacturer instructions for switching your air filter. A dusty filter can lead to your system short cycling, or turn on and off too often, and drive up your energy
  5. bills.
  6. Check attic insulation levels. Nearly 90% of residences in the United States don’t have enough insulation, according to the Insulation Institute. Most southern climates need 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork inspected. Ductwork that has loosened over the years can leak cold air into your attic, walls or crawl space. This can result in huge comfort issues in your house, like hot and cold spots.
  8. Seal holes, doors and windows. Keep muggy air where it belongs by sealing cracks. You can also caulk or weather strip doors to keep more cold air within your home.
