Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to sacrifice comfort or spend a lot to keep your house at the right temperature during warm days.

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

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

Recommended Thermostat Settings for Summer

Most people find setting the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a big difference between your indoor and outdoor temps, your AC expenses will be bigger.

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

While at home: 78 degrees. While that appears too high, there are ways you can keep your residence pleasant without having the air conditioner running all the time.

Keeping windows and blinds closed during the day keeps cold air where it should be—within your home. Some window treatments, like honeycomb shades or plantation shutters, are designed to provide extra insulation and better energy savings.

If you have ceiling fans in your house, the DOE says you can raise thermostat temps about 4 degrees higher without giving up comfort. That’s because they freshen by a windchill effect. Because they cool people, not areas, shut them off when you leave a room.

If 78 degrees still seems too uncomfortable on the surface, try running an experiment for a week or so. Begin by upping your setting to 78 degrees while you’re home. Then, steadily turn it down while adhering to the ideas above. You may be surprised at how comfortable you feel at a higher temperature setting.

While away: 88 degrees. There’s no rationale for keeping the AC working all day while your house is empty. Switching the temperature 7¬¬–10 degrees warmer can save you as much as 5–15% on your electrical costs, according to the DOE.

When you arrive home, don’t be tempted to set your thermostat below 78 to cool your home faster. This isn’t useful and typically produces a more expensive air conditioner expense.

A programmable thermostat is a helpful approach to keep your settings in check, but you need to set programs. If you don’t utilize programs, you run the risk of forgetting to change the set temperature when you take off.

If you need a convenient fix, think about installing a smart thermostat. This thermostat works with with your phone, so it is aware when you’re at home and when you’re away. Then it instinctively adjusts temperature settings for the best savings. How much exactly? An estimated $180 each year on heating and cooling, according to ENERGY STAR.

Another perk of having a smart thermostat? You can use your phone to keep an eye on and change temperature settings from nearly anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR recommends 82 degrees, that could be unpleasant for many families. Many 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 cool, due to your clothing and blanket preference.

We advise running a comparable test over a week, putting your thermostat higher and gradually turning it down to determine the ideal temperature for your residence. On mild nights, you may learn keeping windows open at night and using a ceiling fan is a superior idea than operating the air conditioning.

More Approaches to Conserve Energy This Summer

There are extra ways you can spend less money on cooling bills throughout warm weather.

  1. Install an energy-efficient cooling system. Central air conditioners only work for about 12–15 years and become less efficient as they get older. An updated air conditioner can keep your house comfier while keeping cooling
  2. bills small.
  3. Set regular air conditioning service. Regular air conditioner maintenance keeps your system running properly and might help it run at better efficiency. It can also help extend its life span, since it helps professionals to discover seemingly insignificant issues before they lead to an expensive meltdown.
  4. Replace air filters frequently. Read manufacturer instructions for changing your air filter. A clogged filter can result in your system short cycling, or switch on and off too frequently, and increase your electrical
  5. bills.
  6. Check attic insulation levels. Almost 90% of houses in the USA don’t have enough insulation, according to the Insulation Institute. The majority of 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 the years can seep cold air into your attic, walls or crawl space. This can lead to major comfort issues in your home, including hot and cold spots.
  8. Seal holes, doors and windows. Keep warm air in its place by closing openings. You can also caulk or weather strip doors to trap more conditioned air indoors.
