Whats the Most Energy-Efficient AC Setting?

June 04, 2020

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

But what is the best setting, exactly? We review suggestions from energy professionals so you can choose the best setting for your residence.

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

Recommended Thermostat Settings for Summer

Most families find using the thermostat at 72-73 degrees is most comfortable. However, if there’s a huge difference between your interior and outside temperatures, your cooling bills will be larger.

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

While at home: 78 degrees. While that appears warm, there are ways you can keep your residence pleasant without having the AC going constantly.

Keeping windows and window treatments down during the day keeps cold air where it belongs—inside. Some window solutions, including honeycomb shades or plantation shutters, are created to provide added insulation and better energy efficiency.

If you have ceiling fans in your home, the DOE says you can increase thermostat temperatures about 4 degrees warmer without giving up comfort. That’s since they cool by a windchill effect. Since they cool people, not spaces, switch them off when you move from a room.

If 78 degrees still seems too warm on the surface, try conducting a test for a week or so. Get started by increasing your temperature to 78 degrees while you’re at your house. Then, progressively lower it while using the tips above. You may be shocked at how refreshed you feel at a hotter temperature setting.

While away: 88 degrees. There’s no reason to keep the AC going all day while your residence is vacant. Moving the setting 7¬¬–10 degrees warmer can save you an estimated 5–15% on your electricity bills, according to the DOE.

When you arrive home, don’t be tempted to put your thermostat under 78 to cool your residence more quickly. This isn’t useful and usually results in a more expensive cooling bills.

A programmable thermostat is a useful way to keep your settings in check, but you need to set programs. If you don’t utilize programs, you might forget to change the set temperature when you take off.

If you need a convenient resolution, consider buying a smart thermostat. This thermostat connects with your phone, so it realizes when you’re at your residence and when you’re out. Then it instinctively adjusts temperature settings for the biggest savings. How much exactly? An estimated $180 each year on heating and cooling, according to ENERGY STAR.

Another benefit of having a smart thermostat? You can use your phone to watch and adjust temperature settings from nearly anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR advises 82 degrees, that may be unpleasant for the majority of 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 cool, depending on your pajama and blanket preference.

We recommend running a similar test over a week, moving your thermostat higher and progressively lowering it to pinpoint the ideal temp for your house. On cool nights, you might learn keeping windows open at night and using a ceiling fan is a preferable idea than operating the air conditioner.

More Methods to Use Less Energy This Summer

There are added methods you can spend less money on air conditioning bills throughout hot weather.

  1. Install an energy-efficient cooling system. Central air conditioners only work for about 12–15 years and lose efficiency as they become older. An upgraded air conditioner can keep your residence more comfortable while keeping utility
  2. costs small.
  3. Book annual air conditioner maintenance. Annual air conditioner maintenance keeps your unit working like it should and might help it work at better efficiency. It can also help extend its life expectancy, since it enables techs to spot small issues before they lead to an expensive meltdown.
  4. Change air filters regularly. Read manufacturer instructions for changing your air filter. A dirty filter can lead to your system short cycling, or run too often, and increase your energy
  5. bills.
  6. Inspect attic insulation levels. Just about 90% of houses in the USA don’t have enough insulation, according to the Insulation Institute. The majority of southern climates require 13–14” of attic insulation, while northern climates require 16–18”.
  7. Have your ductwork inspected. Ductwork that has loosened as it’s aged can let conditioned air into your attic, walls or crawl space. This can create big comfort issues in your house, such as hot and cold spots.
  8. Seal cracks, doors and windows. Keep muggy air where it belongs by closing cracks. You can also caulk or weather strip doors to seal more cool air indoors.
