Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to sacrifice comfort or empty your wallet to keep your house at a refreshing setting during hot days.

But what is the best setting, exactly? We review suggestions from energy specialists so you can find the best temp for your home.

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

Recommended Thermostat Settings for Summer

Most people find placing the thermostat at 72-73 degrees is most comfortable. However, if there’s a sizeable difference between your indoor and exterior temperatures, your electrical bills 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 seems too high, there are approaches you can keep your house pleasant without having the AC going constantly.

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

If you have ceiling fans in your home, the DOE says you can move thermostat settings about 4 degrees warmer without giving up comfort. That’s due to the fact they refresh with a windchill effect. As they cool people, not spaces, switch them off when you move from a room.

If 78 degrees still appears too uncomfortable at first glance, try conducting an experiment for a week or so. Start by raising your setting to 78 degrees while you’re at your house. Then, steadily decrease it while following the suggestions above. You might be surprised at how comfortable you feel at a hotter temperature setting.

While away: 88 degrees. There’s no reason to keep the AC running all day while your house is empty. Switching the temperature 7¬¬–10 degrees hotter can save you as much as 5–15% on your cooling bills, according to the DOE.

When you get home, don’t be tempted to set your thermostat under 78 to cool your residence more rapidly. This isn’t productive and typically produces a more expensive AC bills.

A programmable thermostat is a useful method to keep your temp under control, 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 take off.

If you want a hassle-free fix, think about getting a smart thermostat. This thermostat works with with your phone, so it knows when you’re at your residence and when you’re out. Then it instinctively modifies temperature settings for the best savings. How much exactly? Usually $180 each year on heating and cooling, according to ENERGY STAR.

Another plus of using a smart thermostat? You can use your phone to monitor and regulate temperature settings from nearly anywhere.

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

We suggest running a comparable test over a week, putting your temperature higher and steadily decreasing it to select the best temp for your family. On mild nights, you might find keeping windows open at night and relying on a ceiling fan is a better solution than operating the air conditioning.

More Methods to Save Energy During Warm Weather

There are added ways you can conserve money on utility bills throughout the summer.

  1. Buy an energy-efficient AC system. Central air conditioners only last about 12–15 years and get less efficient as they become older. An upgraded air conditioner can keep your house cooler while keeping cooling
  2. bills small.
  3. Schedule regular air conditioner service. Regular air conditioner maintenance keeps your unit operating smoothly and may help it operate at greater efficiency. It can also help prolong its life span, since it helps techs to pinpoint seemingly insignificant problems before they cause a major meltdown.
  4. Change air filters frequently. Use manufacturer instructions for switching your air filter. A dirty filter can lead to your system short cycling, or turn on and off too much, and drive up your utility
  5. bills.
  6. Check attic insulation levels. Almost 90% of residences in the U.S. don’t have proper 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 checked. Ductwork that has loosened over time can leak conditioned air into your attic, walls or crawl space. This can create big comfort problems in your residence, including hot and cold spots.
  8. Seal cracks, doors and windows. Keep humid air where it belongs by sealing holes. You can also caulk or weather strip doors to seal more cold air indoors.
