Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t need to compromise on comfort or spend a lot to keep your home at a pleasant temperature during warm days.

But what is the best temperature, exactly? We review recommendations from energy specialists so you can choose the best temp for your residence.

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

Recommended Thermostat Settings for Summer

Most people find using the thermostat at 72-73 degrees is ideal. However, if there’s a major difference between your interior and outside warmth, your cooling costs will be higher.

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

While at home: 78 degrees. While that sounds too high, there are approaches you can keep your residence pleasant without having the AC on frequently.

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

If you have ceiling fans in your home, the DOE says you can move thermostat temps about 4 degrees higher without compromising comfort. That’s because they cool through a windchill effect. Because they cool people, not areas, turn them off when you exit a room.

If 78 degrees still seems too warm at first glance, try running an experiment for approximately a week. Get started by increasing your temperature to 78 degrees while you’re at your house. Then, steadily turn it down while using the ideas above. You may be amazed at how refreshed you feel at a warmer temperature setting.

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

When you arrive home, don’t be tempted to put your thermostat colder than 78 to cool your home more quickly. This isn’t productive and usually leads to a bigger cooling bills.

A programmable thermostat is a good approach to keep your settings controlled, but it requires setting programs. If you don’t set programs, you risk forgetting to raise the set temperature when you leave.

If you want a handy fix, think over buying a smart thermostat. This thermostat connects with your phone, so it realizes when you’re at your residence and when you’re gone. Then it intuitively adjusts temperature settings for the biggest savings. How much exactly? Typically $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 regulate temperature settings from almost anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR advises 82 degrees, that might be unpleasant for many families. Most people sleep better when their sleeping space is cold, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that may be too cold, depending on your pajama and blanket preference.

We recommend running a similar test over a week, setting your temperature higher and progressively turning it down to find the right temp for your family. On cool nights, you may learn keeping windows open at night and relying on a ceiling fan is a superior solution than running the AC.

More Approaches to Use Less Energy During Hot Weather

There are added approaches you can conserve money on energy bills throughout warm weather.

  1. Install an energy-efficient cooling system. Central air conditioners only work for about 12–15 years and get less efficient as they age. A new air conditioner can keep your home more comfortable while keeping AC
  2. bills down.
  3. Set yearly air conditioner maintenance. Regular air conditioner maintenance keeps your equipment working properly and might help it work more efficiently. It could also help prolong its life cycle, since it enables pros to find little problems before they lead to a big meltdown.
  4. Change air filters often. Read manufacturer instructions for changing your air filter. A dusty filter can lead to your system short cycling, or switch on and off too much, and drive up your energy
  5. bills.
  6. Check attic insulation levels. Almost 90% of houses in the USA don’t have proper insulation, according to the Insulation Institute. Many southern climates require 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 leak cold air into your attic, walls or crawl space. This can create huge comfort issues in your residence, including hot and cold spots.
  8. Seal holes, doors and windows. Keep humid air where it should be by closing holes. You can also caulk or weather strip doors to seal more cool air indoors.
