Whats the Most Energy-Efficient AC Setting?

You shouldn’t have to compromise on comfort or drain your wallet to keep your home at a refreshing temp during the summer.

But what is the best temperature, exactly? We review advice from energy professionals so you can determine the best temp for your family.

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

Recommended Thermostat Settings for Summer

Most households find using the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a big difference between your indoor and outdoor temperatures, your electrical costs will be greater.

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

While at home: 78 degrees. While that sounds warm, there are approaches you can keep your house cool without having the air conditioner running frequently.

Keeping windows and curtains shut during the day keeps cool air where it should be—indoors. Some window treatments, like honeycomb shades or plantation shutters, are made to offer more insulation and better energy efficiency.

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

If 78 degrees still seems too warm initially, try doing an experiment for about a week. Begin by raising your thermostat to 78 degrees while you’re at your residence. Then, gradually lower it while adhering to the tips above. You might be shocked at how comfortable you feel at a warmer temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioner working all day while your residence is empty. Turning the temperature 7¬¬–10 degrees warmer can save you an estimated 5–15% on your electricity bills, according to the DOE.

When you get home, don’t be tempted to switch your thermostat under 78 to cool your residence more quickly. This isn’t effective and usually leads to a more expensive AC cost.

A programmable thermostat is a useful way to keep your settings controlled, but you need to set programs. If you don’t utilize programs, you risk forgetting to raise the set temperature when you leave.

If you want a convenient solution, think over installing a smart thermostat. This thermostat links with your phone, so it realizes when you’re at your residence and when you’re away. Then it intuitively modifies temperature settings for the best savings. How much exactly? Usually $180 annually on heating and cooling, according to ENERGY STAR.

Another advantage of using 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 recommends 82 degrees, that might be too uncomfortable for many families. Most people sleep better when their sleeping space is chilly, so that’s why the National Sleep Foundation advises 60–67 degrees. But that might be too cold, based on your clothing and blanket preference.

We advise following a comparable test over a week, setting your temp higher and slowly turning it down to choose the right setting for your family. On pleasant nights, you may find keeping windows open at night and using a ceiling fan is a better option than running the air conditioner.

More Methods to Conserve Energy During Hot Weather

There are extra methods you can save money on energy bills throughout hot weather.

  1. Get an energy-efficient AC system. Central air conditioners only last about 12–15 years and become less efficient as they age. A new air conditioner can keep your home cooler while keeping electrical
  2. bills low.
  3. Set yearly air conditioning service. Annual air conditioner maintenance keeps your equipment operating smoothly and might help it operate more efficiently. It can also help prolong its life cycle, since it allows technicians to find seemingly insignificant problems before they cause a big meltdown.
  4. Replace air filters often. Follow manufacturer instructions for changing your air filter. A dusty filter can cause your system to short cycle, or switch on and off too often, and raise your electricity
  5. costs.
  6. Inspect attic insulation levels. Nearly 90% of residences in the USA don’t have proper insulation, according to the Insulation Institute. The majority of southern climates should have 13–14” of attic insulation, while northern climates require 16–18”.
  7. Have your ductwork examined. Ductwork that has separated over the years can let cold air into your attic, walls or crawl space. This can result in huge comfort troubles in your residence, such as hot and cold spots.
  8. Seal openings, doors and windows. Keep humid air where it should be by plugging cracks. You can also caulk or weather strip doors to keep more conditioned air within your home.
